23024 Spherical Roller Bearings , 120mm Plain Spherical Bearing 23124

Features

Spherical roller bearings are bearings with spherical rollers assembled between an inner ring with two raceways and an outer ring with spherical raceway. The bearings possess two rows of rollers, mainly withstanding radial load, and at the same time withstanding any of an axial load direction. With high radial load capacity, it is especially suitable for working under heavy load or vibration load. The bearing can also withstand the axial load in both directions, but it cannot bear pure axial load. The outer ring raceway of the spherical roller bearing is spherical, so its self-aligning performance is good and it can compensate the coaxiality error. Generally speaking, the allowable working speed for spherical roller bearings is low.

C-type bearings: there are two steel stamping cages, two rows of spherical roller between which there is an active retaining ring. C-type is the design of second generation, characterized by the use of steel stamping cage, reinforced symmetric rollers, its optimal design with higher rated load than traditional products, wider range of applications, and longer life. When the bearing bear the axial load, it can adjust the load and speed of two rows of rollers, which could balance the load, and avoid stress concentration and single-row rollers be forced.

CA-type bearings: a cage and two rows of spherical roller. The CA model is a second generation design which features of applying precision machined brass cage and reinforced symmetrical rollers, with the same rated load as the C type. It is designed for universal use with the C-type design, especially for large sized model. When the bearing is loaded axially, it can adjust the load of two rows of rollers,so as to balance load, to avoid stress concentration and single-row roller force.

MB-type: a spherical roller bering with fixed ribs on boths sides of inner ring. There is a fixed centre rib and two cages in the middle, spherical symmetry rollers. The centre rib cannot move axially but guide roller well in operation. The load of two rows of bearings cannot be adjusted when the bering is in axial load, it is easy to be force by single row bearing or stress concentration.
Although there is a trend that C, CA-type bearing will replace this structure, but it still has advantages in specific applications, such as large vibration load application.
