Tapered roller bearings are mainly suitable for bearing radial and axial combined loads, while large tapered angle tapered roller bearings can be used to bear radial and axial combined loads. The bearing is a separate type bearing, and its inner ring (including tapered roller and cage) and outer ring can be installed separately. In the process of installation and use, the longitudinal and axial clearance of bearings can be adjusted, and the roller of rear axle hub, a spindle of large machine tool, high power reducer, axle bearing box and conveyor can be pre-interference mounted.

The deep groove ball bearing has a simple structure and is easy to use, and is a type of bearing with the largest production batch and the widest application range. It is mainly used to withstand radial loads and also to withstand certain axial loads. When the radial clearance of the bearing is increased, the function of the angular contact bearing can withstand large axial loads. Used in automobiles, tractors, machine tools, motors, pumps, agricultural machinery, textile machinery, etc.

Tire Wear and Tear. What about your tires? We all know the importance of rotating your tires to promote even wear, but did you know a broken wheel bearing can lead to uneven tire wear too? The looseness of the wheel and the vibration that reverberates through the wheel cause your tires to wear unevenly, meaning you are more likely to have to invest in new tires sooner.

The outer spherical ball bearing with seat consists of two outer spherical ball bearings with a seal on both sides and a cast (or stamped) bearing seat. The inner structure of the outer spherical ball bearing is the same as that of the deep groove ball bearing, but the inner ring of the bearing is wider than the outer ring. The outer ring has a truncated spherical outer surface, which matches with the concave spherical surface of the bearing seat and can adjust automatically. Usually, there is a gap between the inner hole of the bearing and the shaft. The inner ring of the bearing is fixed on the shaft with the top wire, eccentric sleeve or fastening sleeve, and rotates with the shaft. Bearing with seat has a compact structure, convenient loading, and unloading, perfect sealing, and is suitable for simple support. It is often used in mining, metallurgy, agriculture, chemical industry, textile, printing, and dying, conveying machinery, etc.

A rolling bearing is a precision mechanical component that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. The rolling bearing is generally composed of an inner ring, an outer ring, a rolling body, and a cage. The inner ring is matched with the shaft and rotates together with the shaft; the outer ring acts to cooperate with the bearing seat to support the rolling body; The rolling element is evenly distributed between the inner ring and the outer ring, and its shape and quantity directly affect the service performance and life of the rolling bearing; the cage can evenly distribute the rolling elements, prevent the rolling elements from falling off, and guide the rolling elements Rotate for lubrication.

Needle roller bearings are equipped with thin and long rollers (the length of the roller is 3 to 10 times the diameter and the diameter is generally not more than 5 mm), so the radial structure is compact, and the inner diameter and load capacity are the same as those of other types of bearings. The smallest diameter, especially suitable for support structures with limited radial mounting dimensions. Depending on the application, bearings or needle roller and cage assemblies without inner ring can be used. The journal surface and the housing hole surface that match the bearing directly serve as the inner and outer rolling surfaces of the bearing to maintain load capacity and running performance. As with ferrule bearings, the hardness of the raceway surface of the shaft or housing bore. The machining accuracy and surface and surface quality should be similar to the raceway of the bearing ring. This type of bearing can only withstand radial loads. For example universal joint shafts, hydraulic pumps, sheet mills, rock drills, machine tool gearboxes, automotive and tractor gearboxes, etc.

Car Feels Loose. Does your car feel loose? When you hear professional drivers talk about a “loose” car, you may not know what that means. It often refers to the steering of the vehicle, which can include wheel bearings. Wheel looseness, or also called wheel play, is another common symptom of a bad wheel bearing. As the bearing begins to wear down, they become loose inside the wheel hub and spindle, which makes your vehicle feel loose while steering.

When wheel bearings wear out, they can have a significant impact on vehicle performance, leading to increased friction and resistance within the wheel assembly. This extra friction forces the engine to work harder to maintain the same speed, resulting in decreased fuel efficiency. Additionally, worn bearings can cause uneven tire wear, as the compromised alignment and stability of the wheels lead to irregular contact with the road surface. Hitting a pothole or other road hazard can exacerbate bearing damage, potentially causing sudden bearing failure and loss of vehicle control. The deterioration of wheel bearings also affects the proper transfer of torque from the engine to the wheels, further compromising handling and increasing braking distance.

Chances are when you start hearing a loud noise from under the hood of your car as you’re driving, you automatically think it’s an exhaust leak or your car is going to break at any moment. But have you thought about the possibility of a broken — or nearly broken — wheel bearing causing that noise?

Wheel bearings are essential in the operation of your vehicle. More precisely, a wheel bearing is crucial for the proper function of the hub, tire, and wheel assemblies to work together. The wheel bearing allows friction-free movement and rotation of the hub assembly, and thereby provides smooth tire and wheel rotation. Worn-out or damaged wheel bearings can lead to a range of problems that affect vehicle performance and safety, making it essential for drivers to recognize the signs of trouble.

A: Typically, wheel bearings last between 85,000 to 100,000 miles, but this can vary based on driving conditions and maintenance.

The self-aligning ball bearing has two rows of steel balls, the inner ring has two raceways, and the outer ring raceway has an inner spherical shape, which has self-aligning performance. The coaxial error due to the winding of the shaft and the deformation of the casing can be automatically compensated and is suitable for the components in which the support seat hole cannot ensure strict coaxially. The middle bearing is mainly subjected to radial load and can bear a small amount of axial load while being subjected to radial load. It is usually not used to withstand pure axial load, such as bearing a pure axial load, and only one row of steel balls is stressed. Mainly used in agricultural machineries such as combine harvesters, blowers, paper machines, textile machinery, woodworking machinery, bridge cranes and drive shafts.

Thrust roller bearings are used to bear axle loads which are mainly axial loads. Longitudinal combined loads, but the longitudinal loads should not exceed 55% of the axial loads. Compared with other thrust roller bearings, this kind of bearing has a lower friction coefficient, higher speed, and self-aligning ability. The roller of 29000 type bearing is asymmetrical spherical roller, which can reduce the relative sliding of the rod and raceway in work, and the roller is long, big in diameter, large in number and multi-load capacity. Oil lubrication is usually used, and grease lubrication can be used in some low-speed situations. In design selection, priority should be given to selection. Mainly used in hydraulic generators, crane hooks, and so on.

Vehicle Pulling to One Side While Driving. Are you doing the steering, or is the car driving where it wants to? When a wheel bearing corrodes or becomes pitted, the smooth exterior lining is gone and the vibration is transmitted to the tires which may feel like it is “pulling” to one side or the other. As the bearing on one side deteriorates, it puts more pressure on the opposite bearing, leading to uneven wear and increased friction. This uneven wear generates heat, which further accelerates the degradation of the bearing. As a result, the affected wheel may start to wobble or vibrate, robbing the vehicle of its stability and smooth handling, especially when cornering or driving at higher speeds.

A thrust ball bearing is a kind of separated bearing. The bearing ring “seat ring” can be separated from the assembly of the cage steel ball. The shaft ring is a ring matched with the shaft, the seat ring is a ring matched with the bearing seat hole, and there is a gap between the shaft and the ring. Thrust ball bearings can only extract the axial load, one-way thrust ball bearings can only bear the axial load of a room, and two-way thrust ball bearings can bear the axial load of two directions. Thrust ball bearing can not limit the longitudinal displacement of the axis, the limit speed is very low. One-way thrust ball bearings can limit the axial displacement in one direction of shaft and shell, and two-way bearings can limit the axial displacement in two directions. Mainly used in the automobile steering mechanism, machine tool spindle.

Rollers of cylindrical roller bearings are usually guided by two baffles of a bearing ring. The cage, the roller, and the guide ring form a set of components, which can be separated from another bearing ring and belong to separable bearings. This kind of bearing is easy to install and disassemble, especially when it requires interference fit of inner ring, outer ring, and shaft shell. Such bearings are generally only used to withstand radial loads, only single row bearings with inner and outer rings with retaining edges can withstand smaller steady axial loads or larger intermittent axial loads. Mainly used for large motors, machine tool spindles, axle box, diesel engine crankshaft and automobiles, bracket bearing box, etc.

Unusual Noises Coming From the Wheels. Listen carefully. The most common and often most-identifiable symptom associated with a bad wheel bearing is noise coming from the wheel or tire area of the moving vehicle. You may mistake this as engine noise, but when you listen closely you will likely hear grinding or grating that gets louder as the vehicle accelerates. Since wheel bearings are not known for wearing out too frequently, the noise is typically suspected to be something else and the problem gets overlooked.

Spherical roller bearings have two rows of rollers that are primarily used to withstand radial loads and can also withstand axial loads in either direction. This kind of bearing has high radial load capacity, especially suitable for working under heavy load or vibration load, but can not bear pure axial load; good self-aligning performance can compensate the same bearing error. Main uses a paper machine, speed reducer, railway vehicle axle, rolling mill gear box seat, crusher, various industrial speed reducers, etc.

Angular contact ball bearings have a high limit speed and can withstand both longitudinal and axial loads, as well as pure axial loads. The axial load capacity is determined by the contact angle and increases with increasing contact angle. Used for: oil pumps, air compressors, various types of transmissions, fuel injection pumps, printing machinery.
