Product features:

Thrust ball bearing JB4 is usually guided by the two ribs of one bearing ring. Cage, roller and guiding ring form an assembly. This bearing is usually separable bearing. The installation and disassembly of this kind of bearing is convenient. Especially when the inner and outer rings as well as the shaft and housing are required to have interference fit, its advantage is more obvious. This kind of bearing is usually only used to bear radial load. Only the single row bearing, of which the inner and outer rings both have ribs, can bear smaller axial load or larger intermittent axial load. Compared with deep groove ball bearing of the same shape and size, this bearing has larger radial load ability. As for the structure, this bearing is also applicable to high speed rotation.
The roller and ball track of E&K cylindrical roller bearing are designed with convexity modification, which can eliminate the edge stress and improve the service life of bearing.
The ribs of E&K cylindrical roller bearing are designed with inclination angle, which makes it able to bear larger axial load than that of the regular design.
