Product Overview: The 21315 Spherical Roller Bearing
The 21315 bearing is a high-performance component designed to excel in challenging industrial applications, forming an integral part of our robust 21300 Series Spherical Roller Bearings. With precise dimensions of 75mm Bore Diameter, 160mm Outer Diameter, and 37mm Thickness, this bearing is engineered to accommodate heavy radial loads, as well as significant axial loads in both directions. Its inherent self-aligning capability makes it particularly suitable for applications where misalignment between the shaft and housing may occur due to manufacturing errors, shaft deflection, or structural deformation.
At our core, we are dedicated to supplying industrial-grade bearings that ensure optimal machinery performance and longevity. The 21315 bearing features two rows of symmetrical rollers and a common spherical outer ring raceway, allowing it to adapt to angular deviations without compromising performance. This design principle is critical for maintaining operational stability and extending the service life of equipment in demanding environments.
