RKB spherical roller bearings are double-row, self-aligning units that handle radial loads and axial loads in both directions, even when the shaft and housing are not perfectly aligned. They suit heavy equipment where shaft deflection or mounting errors call for self-aligning capability. MR Industrial Accessories supplies this line and helps you select the right part number for your application.

The series designation is based on its main number: examples run from 230/500 to 230/750. The 230 prefix identifies the medium-section spherical roller series, while the digits after the slash give the bore diameter in millimeters. So a 230/500 has a 500 mm bore, a 230/530 has 530 mm, and the remaining sizes follow the same logic. This naming convention makes it easy to spot the size and order the exact replacement.

Typical applications include cement plants, steel mills, crushing plants, mills, high-capacity conveyors, industrial fans and paper machines. In Latin American mining and aggregate operations, these bearings appear in heavy drives where the shaft flexes or the housing is not perfectly aligned. Their self-aligning design lowers the risk of premature failure and simplifies mounting on welded or cast structures.

When selecting a bearing, consider radial and axial load, rotation speed and environmental conditions. Check that the housing and shaft meet the recommended tolerances for self-aligning bearings. Sealing matters: in dusty, wet or particle-laden areas, choose sealed or shielded variants. Lubrication must match temperature and speed—high-viscosity grease or circulating oil as needed. During mounting, align carefully and avoid direct impacts on the rollers.

When replacing a spherical roller bearing, you may find equivalent part numbers from other brands. The 230, 231, 232 and 240 series share standardized dimensions, so a bearing with the same designation from another manufacturer is often interchangeable. Still, verify suffixes for cage, heat treatment or special tolerance, as these can differ between makers. If you are unsure, MR Industrial Accessories can suggest a compatible alternative for your equipment.
