Radialbearing

In power generation applications, cylinder roller bearings are used in turbines and generators to support the rotating components. These bearings are designed to handle high radial loads and can operate at high speeds, making them ideal for power generation applications.

Paper Machines Cylindrical roller bearings are used in paper machines to support the rollers and handle radial loads. They are particularly useful in applications where high speeds and heavy loads are involved.

iii) Direct force method: As the purpose of bearing adjustment is to obtain a specific preload, it would seem sensible to use a method either to produce or to measure the force directly. However, in practice, the indirect methods of adjustment by axial displacement or frictional moment are preferred, because they are simple and can be achieved easily and more cost-effectively.

ii) Frictional moment method: This method is common in large series production because it is fast and can be automated. Since there is a relationship between bearing preload and the frictional moment in the bearings, it is possible to stop adjustment when a frictional moment corresponding to the desired preload has been reached. This can be done if the frictional moment is continuously monitored while setting preload. However, the frictional moment can vary from bearing to bearing, and it also depends on the preservative, the lubricant, and the sealing method.

Different bearing capacity: the contact surface of spherical rolling element and cylindrical rolling element is different. The spherical contact surface is a point, while the cylindrical contact surface is a line. Therefore, under the same size, the radial bearing capacity of cylindrical roller bearings is greater than that of deep groove ball bearings.

The outer raceway is the outer ring of the bearing that holds and guides the rollers. It is typically made of steel and features a smooth surface to minimize friction.

Cylinder roller bearings, also known as cylindrical roller bearings, are widely used in a variety of applications due to their ability to provide support and reduce friction. They are designed with cylindrical rollers that are closely spaced and arranged parallel to the axis of the bearing. This design allows for high radial load capacity and can handle moderate axial loads as well.

Roller and raceway are in linear contact or curved contact after modification, with large radial bearing capacity, suitable for bearing heavy loads and impact loads.

Cylinder roller bearings are used in wind turbine gearboxes to support the rotor and reduce friction. Wind turbines operate in harsh environmental conditions, including high winds and extreme temperatures, which can cause significant wear on the bearings. Cylinder roller bearings are designed to handle these conditions and provide reliable support for the rotating components.

Rollers are cylindrical-shaped rolling elements that support the radial load of the bearing. They are typically made of high-grade steel and are precision-ground to ensure a high level of accuracy and consistency.

This method of adjustment is frequently used when the components of a bearing arrangement are preassembled. The required preload, which is expressed as a negative distance, requires measuring total axial positive displacement (end play) of the shaft relative to a fixed surface. This is typically done with a dial indicator. Shims, intermediate rings or spacers can then be used to adjust axial displacement to the correct negative distance. The width of the shims, intermediate rings or spacers is determined by:

Cylinder roller bearings are used in medical devices such as CT scanners and X-ray machines. These bearings provide precise motion and help reduce vibration and noise, making them ideal for medical applications where accuracy and reliability are crucial.

In the aerospace industry, cylinder roller bearings are used in aircraft engines, landing gear, and other critical components. These bearings are designed to handle high radial loads and can operate at high speeds, making them ideal for aircraft applications. They are also used in satellite systems and other space applications where reliability is crucial.

Different speeds: Because the contact surfaces of the rolling elements of the two bearings are different, their speeds are also different. The larger the contact surface is, the slower the relative speed is. Therefore, deep groove ball bearings with spherical rolling elements have an advantage in speed.

Components of Cylindrical Roller Bearings Cylindrical roller bearings are composed of several key components, including the outer raceway, inner raceway, rollers, cage, and lubrication.

THB Bearings is a professional cylindrical roller bearing types supplier with its own cylinder roller bearing factory. We can produce different types of cylindrical roller bearings according to customers' needs. Cylindrical rollers and raceways are linear contact bearings. With huge load capacity, cylindrical roller bearing mainly bears radial load. The friction between the rolling element and the retaining edge of the ring is small, which is suitable for high-speed rotation. According to whether the ring has ribs, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU and NN. Cylindrical roller bearing has a separable structure with inner ring and outer ring.

Railway Applications Cylindrical roller bearings are used in railway applications to support the wheels and handle radial loads. They are preferred over other types of bearings because they can handle high speeds and heavy loads.

Thrustbearing

The method used depends on, among other things, the application design and the number of bearings to be mounted. Individual adjustment can accommodate enough tolerance stack-up so that if individual components are produced to normal tolerances, the desired preload can be achieved with a relatively high degree of accuracy.

Cylindrical roller bearings produced by THB Bearings, a cylindrical roller bearing types supplier owning its own cylinder roller bearing factory, have many designs, series, and sizes. The main design difference between the cylindrical roller bearing types is as follows.

Gearboxes Cylindrical roller bearings are often used in gearboxes to support the gears and handle radial loads. They are particularly useful in applications where space is limited, as they can support heavy loads without taking up too much space.

Cylindrical roller bearings without ribs on the inner ring or outer ring, the inner ring and outer ring can move relative to the axial direction, so it can be used as a free end bearing. Cylindrical roller bearings with double ribs on one side of the inner ring and outer ring and a single rib on the other side of the ring, can bear a certain degree of axial load in one direction. Generally, stamping steel cages or solid cages made of copper alloy cars are used.

i) Axial displacement method: The axial displacement method is based on the relationship between the preload force and the elastic deformations within the bearing arrangement. The requisite preload can be determined from the preload force/axial displacement diagram below.

The automotive industry is one of the primary applications of cylinder roller bearings. These bearings are used in various parts of a car, including the engine, transmission, and wheel hubs. In the engine, cylinder roller bearings provide support for the crankshaft and camshaft, reducing friction and allowing for smooth operation. In the transmission, they are used to support the gears and reduce friction during shifting. In the wheel hubs, they provide support for the wheel and axle, allowing for smooth and efficient rotation.

Cylindrical roller bearings are separable bearings, which are very convenient for installation and disassembly. Cylindrical roller bearings can withstand larger radial loads and are suitable for use in high-speed running situations.

The main difference between the two types of bearings lies in rolling elements, one is spherical rolling element, the other is cylindrical rolling element. It is precisely because the following differences between them have occurred.

a. Single, universally matchable bearings: Universally matchable bearings are specifically manufactured so that, when mounted in random order but immediately adjacent to each other, preload within a predetermined range and effective load sharing will result without the use of shims or similar devices.The preload classes areGA, GB and GC.

Lubrication is essential to ensure the proper function of cylindrical roller bearings. Grease or oil is used to reduce friction and heat generated by the bearing, prolonging its lifespan and improving its overall performance.

Machine Tools Cylindrical roller bearings are used in machine tools such as lathes and milling machines to support the spindle and handle radial loads. They are preferred over other types of bearings because they can handle heavier loads and provide greater stiffness and accuracy.

Compared with ball bearings, cylindrical roller bearings have higher radial load capacity. The design of cylindrical rolling elements also allows such bearings to accept relatively faster speeds than other forms of roller bearings.

Cylindrical roller bearings are suitable for rigid double-supported short shafts, shafts that cause axial displacement due to thermal elongation, and machine parts that need to be separated for installation and disassembly. Different types of cylindrical roller bearings created by THB Bearings, a professional cylinder roller bearing manufacturer, can meet various demands from customers all over the world. Cylindrical roller bearings are mainly applied in the following industries: large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, steel rolling mills, and vibrating screens, lifting and transportation machinery.

Adjustment means setting the internal clearance or preload in an adjusted bearing arrangement during assembly. In operation, a certain clearance/preload ⁠—or only preload ⁠—range then arises. Axial preload in an adjusted bearing arrangement with single-row, angular, contact ball bearings, tapered roller bearings and deep-groove ball bearings is produced by displacing one bearing ring axially, relative to the other, by an amount corresponding to the desired preload force. There are basically two principal methods to adjust preload: individual adjustment and collective adjustment.

The simplest method of applying preload is to use a wave spring. The spring acts on the outer ring of one of the two bearings. This outer ring must be able to be axially displaced. In the diagram below, the bearing arrangement comprises a preloaded, single-row, deep groove ball bearing at each end of the shaft.

The processing requirements for the shaft or the seat hole are high, and the relative deflection of the outer ring axis after the cylindrical roller bearing is installed must be strictly controlled to avoid contact stress concentration.

Cylinder roller bearings are commonly used in heavy machinery such as cranes, excavators, and construction equipment. These bearings provide support for the rotating components and help reduce friction, allowing for smoother and more efficient operation. They are also used in conveyor systems, printing presses, and other industrial equipment that requires precise and reliable motion.

The preload force remains practically constant, even when there is axial displacement of the bearing as a result of thermal elongation. The requisite preload force can be estimated using:

Four-row cylindrical roller bearings are usually separated type, with heavy load capacity, mainly bear radial load, and are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.

Single-row cylindrical roller bearings are usually only subjected to radial force. Compared with ball bearings of the same size, its radial bearing capacity is increased by 1.5-3 times, with good rigidity and impact resistance. Single row cylindrical roller bearings with unidirectional or bidirectional axial force structures can also be chosen to meet your needs.

Axial bearing

The noise is different: When the speed of the bearing of the same size is the same, the noise of the cylindrical roller bearing is greater than that of the deep groove ball bearing. This is also because the friction caused by the different contact surfaces of the rolling elements of the two bearings is different. The greater the friction surface, the greater the noise.

b. Matched bearing sets: Bearings can be supplied as a complete bearing set consisting of two, three or more bearings. The bearings are matched to each other during production so that when mounted immediately adjacent to each other and in the specified order, preload within a predetermined range and effective load sharing result without the use of shims or similar devices. The preload classes areGA, GB, and GC.

b. Collective adjustment: This method can also be referred to as “random statistical adjustment.” Using this method, the bearings, shaft, housing and any other components are manufactured to normal tolerances. The components, which are considered fully interchangeable, are assembled randomly. For tapered roller bearings, this interchangeability also extends to the inner ring assemblies and outer rings. To avoid high machining costs and the use of precision bearings, it is assumed that, given the limiting values of the tolerances, it is statistically improbable that the extremes of the tolerance stack-up occurs. If, however, accurate preload is to be obtained with as little scatter as possible, manufacturing tolerances must be narrowed. The advantage of collective adjustment is that no inspection is necessary and no extra equipment is needed when mounting the bearings.

Cylindrical roller bearings can be divided into single-row, double-row and multi-row cylindrical roller bearings according to the number of rows of rolling elements. Bearings of different structures are also shown in the design of the position of the ribs. Among them, the commonly used cylindrical roller bearings have the following forms.

In conclusion, cylinder roller bearings are used in a wide range of applications where high precision and reliability are required. They are designed to handle high radial loads, operate at high speeds, and provide smooth and efficient motion. From the automotive industry to aerospace and medical equipment, cylinder roller bearings play a critical role in many essential applications.

Electric Motors Cylindrical roller bearings are commonly used in electric motors to support the rotor and handle radial loads. They are often used in motors with high radial loads, such as those used in industrial applications.

a. Individual adjustment: With individual adjustment, each bearing arrangement is adjusted separately using nuts, shims, spacer sleeves, crush sleeves, etc. Measuring and inspection procedures are used to ensure that the established nominal preload is obtained with the least possible deviation. There are various methods to obtain the required preload:

Cylindrical roller bearings are an essential component of many industrial applications, offering high radial load capacity and moderate thrust load capacity. These bearings are widely used in various fields, from electric motors and gearboxes to machine tools and paper machines.

The railroad industry is another common application for cylinder roller bearings. These bearings are used in locomotives, freight cars, and passenger trains to provide support and reduce friction. They are designed to handle heavy loads and operate in harsh environmental conditions.

Spring loading is also a common method of applying preload to angular contact ball bearings in high-speed grinding spindles. The method is not suitable for bearing applications where a high degree of stiffness is required, where the direction of axial load changes or where indeterminate peak loads can occur.

This type of bearing allows a very small angular error (inclination) between the axis of the inner ring and the axis of the outer ring, only 2'～4'. Therefore, the machining accuracy of the shaft and the bearing seat is relatively high. Otherwise, uneven load or stress concentration is likely to occur in the contact part of the raceway. But after correcting the roller or raceway contact bus bar, the occurrence of stress concentration can be reduced.

For small electric motors, values of between 0,005 and 0,01 are used for the factor k. If preload is used primarily to protect the bearing from the damage caused by external vibrations when stationary, then greater preload is required and k = 0,02 should be used.

The friction coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing.
