230xx Spherical roller bearings
Description
The 23000 series self-aligning cylindrical roller bearings are the self-aligning version of the 32000 series tapered roller bearings. We use them when the bearing has to bear a large axial and radial load, and the angular deviation in the drive must also be corrected. The bearing consists of a five-digit identification number, of which the first three digits are "230". The last pair of digits can range from 00 (in theory) to 99 and shows the nominal diameter (shaft size) of the bearing's inner ring. The 23000 series barrel roller bearings can also be made with a tapered (1:12) inner ring.
Other features of the 23000 series bearings are identified by prefixes or suffixes. The most common pre/postmarks for 23000 series bearings are: SS=stainless material, MB=machined bronze basket, CC=pressed steel basket, K=tapered (1:12) inner ring, W33=lubrication groove and holes on the outer ring.
