Spherical roller bearings 230/750-K-MB

NOVEMBER 02, 2022

Spherical roller bearings are double row,self-retaining units comprising solid outer rings with a concave raceway,solid inner rings and barrel rollers with cages.The inner rings have cylindrical or tapered bores.

The symmetrical barrel rollers orient themselves freely on the concave outer ring raceway. As a result, shaft flexing and misalignment of the bearing seats are compensated.

Many sizes of spherical roller bearings are of an X-life design. These bearings have improved kinematics and optimised surfaces,are made from higher performance materials and do not have a rigid central rib. As a result,the basic dynamic load rating and, under identical operating conditions,the basic rating life of the bearings is significantly improved.In certain applications, this means that a smaller bearing arrangement can be designed.
X-life spherical roller bearings have the suffix E1 and are indicated in the dimension tables.
