Product Overview: The 21317 Spherical Roller Bearing
The 21317 bearing is a high-capacity Spherical Roller Bearing, part of our comprehensive 21300 Series. Designed with two rows of rollers and a common spherical raceway in the outer ring, this bearing is engineered to accommodate heavy radial loads and axial loads in both directions. Its primary advantage lies in its exceptional ability to compensate for angular misalignment between the shaft and the housing, making it ideal for applications prone to shaft deflection or mounting errors.
With precise dimensions of 85mm bore diameter, 180mm outer diameter, and 41mm thickness, the 21317 bearing provides robust and reliable performance in demanding industrial environments. As a trusted supplier of industrial bearings and mechanical parts, we ensure these bearings meet stringent industry standards for durability and operational efficiency. They are indispensable components in heavy machinery, providing smooth rotation and extended service life even under challenging conditions.
