Do you know the types of rolling bearing ?

Types of rolling bearing---Cylindrical roller bearing

The rollers of cylindrical roller bearings are usually guided by two retaining edges of a bearing ring, and the cage roller and guide ring form a combination that can be separated from another bearing ring, belonging to separable bearings.

This type of bearing is easy to install and disassemble, especially when it requires interference fit between the inner and outer rings and the shaft or housing. This type of bearing is generally only used to withstand radial loads, and only single row bearings with both inner and outer rings equipped with ribs can withstand small steady-state axial loads or large intermittent axial loads.

Types of rolling bearing---Self-aligning roller bearing

This type of bearing is equipped with spherical rollers between the outer ring of the spherical raceway and the inner ring of the double raceway. According to the different internal structures, it is divided into four types: R, RH, RHA, and SR. Due to the fact that the center of the circular arc of the outer raceway is consistent with the center of the bearing, it has centering performance and can automatically adjust the axis misalignment caused by the deflection or non concentricity of the shaft or outer shell, and can withstand radial loads and bidirectional axial loads.

Types of rolling bearing---Thrust self-aligning roller bearing

In this type of bearing, the spherical rollers are arranged in an inclined manner. Due to the spherical raceway surface of the seat ring, it has self-aligning performance, allowing the shaft to tilt slightly. The axial load capacity is very large, and it can withstand several radial loads while bearing axial loads. Oil lubrication is generally used during use.

Types of rolling bearing---Tapered roller bearing

This type of bearing is equipped with conical rollers, which are guided by the inner ring large flange. The design ensures that the vertices of the inner ring raceway surface, outer ring raceway surface, and roller rolling surface intersect at a point on the bearing centerline. Single row bearings can withstand radial loads and unidirectional axial loads, while double row bearings can withstand radial loads and bidirectional axial loads, making them suitable for withstanding heavy loads and impact loads.

Types of rolling bearing---Thrust roller bearing

Thrust roller bearings are used for shafts that mainly bear axial loads, with combined longitudinal loads, but the longitudinal load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this type of bearing has a lower friction coefficient, higher rotational speed, and has self-aligning ability. The rollers of the 29000 type bearing are asymmetric spherical rollers, which can reduce the relative sliding between the stick and the raceway during operation. The rollers are long, have a large diameter, have a large number of rollers, and have a large load capacity. Oil lubrication is usually used, and in some low-speed situations, grease lubrication can be used.

Types of rolling bearing---Thrust cylindrical roller bearing

Composed of washer shaped raceway rings (shaft rings, seat rings), cylindrical rollers, and cage components. Cylindrical rollers are processed with convex surfaces, resulting in uniform pressure distribution between the roller and the raceway surface. They can withstand unidirectional axial loads, have high axial load capacity, and strong axial rigidity.

Types of rolling bearing---Thrust needle bearing

Separable bearings consist of raceway rings, needle rollers, and cage components, which can be combined with thin raceway rings produced by stamping or thick raceway rings produced by cutting. Non separable bearings are integral bearings composed of precision stamped raceway rings, needle rollers, and cage components. They can withstand unidirectional axial loads, occupy small space, and are conducive to compact mechanical design. Most bearings only use needle rollers and cage components, and use the installation surface of the shaft and housing as the raceway surface.

Types of rolling bearing---Thrust tapered roller bearing

This type of bearing is equipped with conical rollers (with a spherical end), which are accurately guided by the retaining edges of the raceway rings (shaft rings, race rings). The design ensures that the apex of the raceway surfaces of the shaft rings and race rings, as well as the conical surfaces of the roller rolling surfaces, intersect at a point on the bearing centerline. Unidirectional bearings can withstand unidirectional axial loads, while bidirectional bearings can withstand bidirectional axial loads.
