Timken Spherical Roller Bearings Guide
Product Description
The 231/670 YMB Timken spherical roller bearing consists of an inner ring, an outer ring, two rows of spherical rollers, and a one-piece, inner-ring-piloted, machined-brass cage. This configuration provides high radial load capacity, bidirectional axial load support, and self-aligning capability to accommodate shaft deflection and misalignment. The high-performance machined-brass cage guided by the inner ring provides excellent strength, wear resistance, and reliable roller guidance, helping maintain stable operation under heavy loads, shock conditions, and demanding operating environments.
The 231/670 YMB bearing is widely used in mining equipment, crushers, conveyors, industrial gearboxes, rolling mills, and heavy-duty machinery. It is particularly suitable for applications requiring high load capacity, misalignment compensation, reliable roller control, and long service life under continuous or severe operating conditions.
