Tapered roller bearings are usually detachable, that is, tapered inner ring assemblies with rollers and cage assemblies may be mounted separately from the tapered outer ring (outer ring).
About Bearing:
Spherical roller thrust bearings have specially designed raceways
and accommodate a large number of asymmetrical rollers. The rollers have an optimum conformity with the washer raceways to
optimize load distribution along the roller length. Therefore, they
can accommodate relatively high speeds, heavy axial loads in one
direction and heavy radial loads. The load is transmitted between
the raceways at an angle to the bearing axis. Spherical roller
thrust bearings are self-aligning and insensitive to static
misalignment of the shaft relative to the housing.
The metric tapered roller bearings are designed according to the
European International Standard ISO 492 and are divided into
subfamilies based on their outer diameter and height.
This typology is the standard kind, which allows them to be used in
many applications, thanks to the combined load distribution
and high performance at optimum speeds.
