Timken Spherical Roller Bearings Guide
Product Description
The 21310 EJ Timken spherical roller bearing consists of an inner ring, an outer ring, two rows of spherical rollers, and stamped nitrided steel cages. This configuration provides high radial load capacity, bidirectional axial load support, and self-aligning capability to accommodate shaft deflection and misalignment. The high-performance stamped nitrided steel cages provide excellent wear resistance and reliable roller guidance, helping maintain stable operation under heavy loads, shock conditions, and demanding operating environments.
The 21310 EJ bearing is widely used in mining equipment, crushers, vibrating screens, conveyors, gear drives, paper machinery, fans, and other industrial equipment. It is particularly suitable for applications requiring high load capacity, misalignment accommodation, shock resistance, and reliable operation under continuous or severe working conditions.
