FAG Spherical Roller Bearings Guide

Product Description

The 249/950-B-K30-MB FAG spherical roller bearing consists of an inner ring, outer ring, two rows of spherical rollers, and a solid brass cage. Its self-aligning design accommodates angular misalignment and shaft deflection while supporting very high radial loads and axial loads in both directions. The K30 tapered bore has a 1:30 taper, while the MB machined brass cage provides robust support under heavy-duty operating conditions.

The 249/950-B-K30-MB bearing is suitable for steel and metallurgy, mining and cement, power generation, paper machinery, material handling, and heavy industrial equipment. Its high radial load capacity and self-aligning capability make it suitable for heavy loads, shaft deflection, and alignment deviations. FAG application documentation shows large spherical roller bearings with K30 and MB designs in heavy power-generation applications, while FAG also specifies large MB spherical roller bearings for demanding paper-industry bearing positions.
