In RKB spherical roller thrust bearings the load is transmitted from one raceway to the other under an angle of about 50° related to the bearing axis.
They can take over heavy axial loads and simultaneously they can accommodate radial loads with values of up to 55% of the axial load magnitude.
An important feature of spherical roller thrust bearings is their self-aligning capability, thanks to the design of the housing and shaft washer raceways with a large number of asymmetrical rollers and the proper conformity with the paths.
RKB spherical thrust bearings have a machined brass cage guided by a sleeve clamped in the shaft washer bore (suffix EM). The shaft washer and the cage with rollers form a non-separable unit.
The overall dimensions of the spherical roller thrust bearings are in accordance with ISO 104:1979, so that they are interchangeable with different designs, even the earlier ones (suffix B).
Where the cage guiding sleeve also serves as a spacer sleeve, the spacer sleeve needed between the shaft washer and the shaft shoulder has to be checked and, if necessary, remachined when substituted with different bearing designs.
These RKB bearings as standard are manufactured to normal tolerance class as specified in ISO 199:1997. However the tolerance for the total height is tighter than that specified by ISO.
