Features

Spherical roller bearings consist of an outer ring with spherical roller raceway and a inner ring with a double raceway, one or two cages and a set of spherical rollers. As the raceway center of outer ring is the same with the bearing center of the same bearing, it can be self-aligned, and adjust automatically the tilt or deflection of the shaft, which caused by the angular error between the shaft and housing. It can bear a large radial load with a certain two-way axial load, for heavy load or vibration in particular.

DCM can produce high quality SRB as the customer requests.We are happy to produce further construction methods. Please do not hesitate to contact us for special bearing characters.We can also supply OEM service.

There is no rib for both sides of 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.

There are ribs on both sides of inner rings for 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 is 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.
