Pillow block bearing unit consists of a set of bearings and bearing seats. Most people say that the housing bearing unit is the same as the pillow block bearing, but in fact there are many designs of bearing units, and the pillow block bearing is the most widely used type of bearing unit on the market. According to the bearing type, there are ball bearing units, roller bearing units, and aligning ball bearing units; roller bearing units include spherical roller bearing units, tapered roller bearing units, needle roller bearing units; and sleeve bearing units. . According to different applications, there are different designs, such as high-temperature bearing units, stainless steel bearing units, high-speed bearing units, maintenance-free bearing units, ceramic bearing units, corrosion-resistant bearing units, etc.; bearing seat (pillar or vertical bearing seat) Includes designs for cast iron, ductile iron, heat-resistant plastics, stainless steel, ceramics and other diverse materials. The color of the bearing seat can be made into black, blue and green. There are several types of pillow block bearings available, each suitable for different applications. The most common types include:

Pillow block bearings are usually used in harsh working environments such as mud, dust, moisture and high temperatures. The grease inside the bearing will deteriorate in a short period of time. Therefore, it is necessary to grease and re-lubricate the seated spherical ball bearings at appropriate intervals, and replace the deteriorated grease with fresh grease. FS cast iron outer spherical ball bearings are equipped with oil nozzles and can be re-lubricated, ensuring perfect performance and long service life in any working environment. Grease can be selected from normal temperature, low temperature and high temperature grease according to the ambient temperature of use. There is an oil groove on the outer ring of the bearing, which can better ensure that the grease can be smoothly injected into the bearing from the oil nozzle.

The bearings and bearing seats are precision machined, and the bearings and bearing seats are completely interchangeable, making it easy to replace the bearings at any time.

Despite their reliability, pillow block bearings can still experience certain problems. Here are some common questions and troubleshooting tips:

Cast iron is made primarily of iron and contains important trace amounts of carbon and silicon. Cast iron is a natural composite material whose properties are determined by its microstructure, i.e. the stable and metastable phases formed during solidification or subsequent heat treatment. The main microstructural components of cast iron are: the chemical and morphological forms that carbon takes, and the continuous metallic matrix in which carbon and/or carbides are dispersed. Cast iron is the most common material for pillow block bearing seats.

The outer diameter of the pillow block bearing and the inner diameter of the bearing seat adopt a spherical matching method, with automatic alignment function, which can effectively compensate for errors such as axis misalignment and installation bottom surface deformation caused by installation.

Pillow block bearings are suitable for various industrial and mechanical fields, including general machinery, motors, automobiles, metallurgy, mining and other industries. It is especially suitable for occasions with heavy load, impact, vibration load and fast rotation speed. Bearing seats are widely used in various transmission mechanisms and bearing supports, such as motors, hydraulic machinery, textile machinery, machine tools, etc. Although pillow block bearings and bearing seats are both important components of mechanical parts, their functions and positioning are slightly different. Pillow block bearing mainly carries the bearing load, orientation and stability; while the bearing seat is set on the shaft to support the bearing and position the axis center.

Consider the rotational speed of the shaft. Different bearings have specific speed limits and exceeding these limits can cause overheating and damage. Select bearings that can operate within the required speed range.

Before tightening the bolts, align the bearing unit with your hand or a rubber mallet to determine the final mounting position.

Excessive noise may indicate misalignment, insufficient lubrication, or worn components. Check bearing alignment, lubrication and condition for any abnormalities.

Pillow block bearing is one of the most common bearings in mechanical equipment. It consists of an inner ring, an outer ring, rollers, a cage and a seat. Among them, the inner and outer diameters of the inner ring and outer ring are different in size, which can bear axial load and radial load at the same time. Pillow block bearing is widely used in automobiles, mechanical equipment and other fields. Its main function is to support and reduce friction. Aubearing will use this blog to introduce the basics of pillow block bearing. Provide constructive suggestions to help you choose the right bearings.

Both sides of the pillow block bearing are equipped with heat-resistant and oil-proof rubber sealing rings and steel plate dust covers for combined sealing. The dust cover is assembled on the outer diameter of the inner ring of the bearing and rotates together with the inner ring. It can effectively prevent external foreign matter from entering the inside of the bearing and protect the bearing against external pressure. This combined seal consisting of a sealing ring and a dust cover can prevent Mud, dust, and moisture enter the inside of the bearing, and at the same time, it prevents the grease inside the bearing from leaking out. This enables the bearings to maintain perfect working performance even in harsh working environments.

Plastics refer to a number of organic, synthetic or processed materials, mostly high molecular weight thermoplastic or thermoset polymers, that can be made into objects, films or filaments. Common plastic materials include acetal, nylon/polyamide, and PTFE/Teflon.

Like all bearings, pillow block bearings require proper lubrication to reduce wear and friction. There are three types of commercial lubricants: grease, oil, and solid film. Lubrication options include manual and self-lubricating. Manual lubrication requires a housing-mounted pump or fitting to deliver oil or grease to the friction points of the bearing. Self-lubricating bearings are made of materials such as oil-impregnated bronze or graphite/metal alloys and require no external lubrication.

Acetal polymers are semi-crystalline. They have excellent inherent lubricity, fatigue resistance and chemical resistance. Acetal can have problems with outgassing at high temperatures and can become brittle at low temperatures. Glass filled and added lubrication grades are available, but not flame retardant grades. Brands include Celcon® (Hoechst Celanese), Delrin® (DuPont), Thermocomp® (LNP), Ultraform® (BASF) and Acetron® (DSM Polymers).

How to Choose Pillow Block Bearings Pillow block bearings protect bearings during operation and provide a fixture for bearings in use. Bearing housings can be made from a variety of materials with different properties. The material the bearing is made of has a significant impact on the performance of the bearing unit.

Position the shaft in place by gently securing the housing to the mounting structure. Bridge the housing mounting bolt slots with heavy-duty washers or heavy-duty spring lock washers. This may help prevent loosening.

Roller bearings use cylindrical or tapered rollers instead of balls. They can handle heavier loads and are better suited for applications with higher shock and shock loads.

While chock bearings can handle moderate speeds, they may not be suitable for high-speed applications. Consider alternative bearing types designed for high-speed operation.

The internal structure of the pillow block bearing can be the same as the 6200 and 6300 series of deep groove ball bearings, so the FS seated outer spherical ball bearing can withstand radial load and a certain axial load. And the working noise is low.

Lubricate bearings regularly with recommended grease or oil. Lubrication helps reduce friction and prevent excessive heat build-up.

Choosing the right pillow block bearing for your application is critical to ensuring optimal performance and service life. The environment, load and size of the mounting shaft are major factors in selecting the appropriate pillow block bearing. In environments where contaminants are a concern, a solid bearing housing with some sealing may be the best choice. High capacity loads or harsh environments may require heavy duty pillow block bearings or even plummer housings. For light loads, a standard pillow block with a bore size matching the mounting shaft may be sufficient. Popular for its highly calculated and balanced engineering design which has been successful in the industry for quite some time. Pillow block bearings feature a straightforward design that requires little or no effort to install and provides high performance and durability. Pillow block bearings are mainly used in less industrialized environments. Please consider the following factors when selecting a pillow block bearing:

Evaluate the environmental factors present in the application environment, such as temperature, humidity, and contaminants. Choose bearings with appropriate seals or guards to prevent these conditions.

Determine the magnitude and type of loads the bearing will encounter. This includes radial and axial loads. Make sure the selected bearings can handle the expected loads without premature failure.

Due to its excellent structural characteristics, pillow block bearing is widely used in various mechanical equipment, such as metallurgical equipment, mining equipment, water pumps, fans, machine tools and other fields. At the same time, pillow block bearing can also withstand certain radial and axial loads, so it is also commonly used in automobiles, motors and other industries.

Steel is a commercial iron with a carbon content of up to about 1.7%, making it an important alloying component. Malleable under the right conditions, distinguished from cast iron by its ductility and lower carbon content. Bearings are usually made of high carbon steel such as 52100.

Pillow block bearings are wear-resistant bearings contained within a solid cast iron, ductile iron or cast steel housing unit, also known as pillow block bearing units, which means they are self-contained, lubricated, sealed and can be installed in equipment superior. Mounted bearings are usually bolted to the surface so that the connected shaft is parallel to the surface. There are two types of bearing seats for pillow block bearings: integral bearing seats and split bearing seats. Solid pillow block bearing is a one-piece bearing seat, while split pillow block bearing is a two-piece bearing seat. The connection device can be a set screw, eccentric lock, single or double set ring, concentric lock or tapered adapter. Each type of pillow block bearing has its own advantages and disadvantages. Seals also vary, including gap seals, light contact seals, heavy contact seals and auxiliary seals. Choosing the proper mounting method and seals will extend bearing life. If installed correctly, pillow block bearings can last for many years without needing to be replaced.

The inner ring channel and the parts around it that need to be hardened are normally quenched, and the extended end of the inner ring where the set screw is mounted is partially tempered at high temperature to maintain toughness and impact resistance. After local high-temperature tempering around the screw holes in the inner ring, the bearing obtains better performance, which can prevent the screws from loosening during the operation of the bearing. At the same time, tightening the screws very tightly will not cause the inner ring to burst.

Schedule regular inspections to check for signs of wear, damage or contamination. Promptly replace any worn or damaged parts.

Pillow block bearing is a type of bearing widely used in mechanical equipment. Pillow block bearings can be divided into multiple subcategories according to their load-bearing capacity and structural form, such as deep groove ball bearings, aligning ball bearings, angular contact ball bearings, etc. The structural feature of pillow block bearing is that the inner and outer spherical surfaces are in contact, and the balls are separated by a ball cage, so it has a certain load-bearing capacity and self-centering performance.

Bearing seats are generally cast. Commonly used bearing seats include vertical seat (P), square seat (F), boss square seat (FS), boss round seat (FC), diamond seat (FL), slider seat (T), narrow vertical seat Type seat (PA), high center vertical seat (PH), hanging bearing seat (FB), adjustable diamond seat (FA), etc.
