Product Overview: The 21312 Spherical Roller Bearing
The 21312 bearing is a robust and high-performance component within our 21300 Series of Spherical Roller Bearings. Engineered to excel in demanding industrial applications, this bearing features a bore diameter of 60 mm, an outer diameter of 130 mm, and a thickness of 46 mm. Its design incorporates two rows of rollers, with a common spherical raceway in the outer ring and two inner ring raceways inclined at an angle to the bearing axis. This unique configuration allows the 21312 bearing to accommodate significant angular misalignment of the shaft relative to the housing, as well as handle heavy radial and axial loads in both directions.
As a key product for reliable power transmission and machinery operation, the 21312 spherical roller bearing is manufactured to stringent industry standards. It is particularly well-suited for environments where heavy shock loads, vibrations, and shaft deflections are common. Our commitment to providing high-quality industrial bearings ensures that the 21312 delivers exceptional performance, extended service life, and contributes to the overall efficiency and stability of your machinery. Explore our full range of spherical roller bearings to find the optimal solution for your heavy-duty applications.
