Double row tapered roller bearing
RKB Europe
Suitable for combined radial and axial loads, they locate axially the shaft in both directions with the stated axial end play (also defined as BEP - Bench End Play) or given preload.
The basic styles are two-row converging TDI configuration and two-row diverging TDO configuration.
Rings and rollers are made of high chrome through hardening steels or case hardened carburizing alloy steels depending on the application.
Cages for RKB double row taper roller bearings are stamped pressed steel. A steel pin-type cage, which allows a larger complement of rollers for higher capacity, is also available.
This style of bearing set simplifies design and reduces the danger of bearing clearance changes due to axial shaft expansion.
It is important the definition of the proper internal play related to the application.
