Product Overview: The 21305 Spherical Roller Bearing
The 21305 bearing is a high-performance component, part of our robust 21300 Series Spherical Roller Bearings. Engineered to withstand heavy radial and axial loads, this bearing is designed to accommodate significant angular misalignment of the shaft relative to the housing. Its robust design features two rows of rollers with a common spherical raceway in the outer ring, allowing for excellent self-aligning capabilities.
As a leading supplier of industrial bearings and mechanical parts, we ensure that our 21305 bearings meet stringent industry standards, providing reliable performance and exceptional longevity in the most demanding industrial environments. The 21305 bearing, with its precise dimensions of 25mm bore, 62mm outer diameter, and 25.5mm thickness, is a critical component for machinery requiring robust rotational support under conditions of heavy loads, shocks, and potential shaft deflection. Explore our comprehensive range of spherical roller bearings to find the ideal solution for your industrial applications.
