Product Overview: The 21313 Spherical Roller Bearing
The 21313 bearing is a high-performance component within our 21300 Series Spherical Roller Bearings. With precise dimensions of 65mm bore diameter, 140mm outer diameter, and 33mm thickness, this robust bearing is engineered to withstand extremely heavy radial loads and significant axial loads in both directions. Its design incorporates two rows of barrel-shaped rollers, which are self-aligning, allowing it to accommodate angular misalignment between the shaft and the housing that can arise from shaft deflection, mounting errors, or frame distortions.
As a critical element in heavy industrial machinery, the 21313 spherical roller bearing provides exceptional reliability and durability in the most challenging operating environments. Its inherent self-aligning property ensures even load distribution across the rollers, preventing premature wear and extending service life. We supply this bearing manufactured to stringent industry standards, making it an ideal choice for applications demanding high load capacity and resilience.
