China supplier NSK bearings Japanese Split Spherical roller bearing with brass(steel)cage 23030CA 23030

Description

1) The spherical roller bearing has two rows of rollers, a common sphered raceway in the outer ring, and two inner ring raceways inclined at an angle to the bearing axis.

2) The bearings are inherently self aligning and robust, which makes the bearings insensitive to misalignment of the shaft relative to the housing and to shaft deflection or bending.

3) The two rows of rollers make the bearings able to carry high axial loads acting in both directions.

4) There are many sizes and designs for this type bearings, depending on bearing the arrangement of the floating guide and the design of the inner ring and/or cages.

Types of spherical roller bearing:
C: Stamped steel retainer and strengthened symmetric rollers for considerably higher load ratings;
CA: one piece brass retainer and strengthened symmetric rollers;
exchange with C design, especially for large size.
MB: Two-piece precision-machined brass retainer and strengthened symmetric rollers;
equivalent to C design in load capacity.
CC: steel cage, replace traditionalbrass cage.
E: Third generation design to improve stress distribution for much longer service life
