Product Overview: The 21320 Spherical Roller Bearing
The 21320 bearing is a high-performance component, belonging to our robust 21300 Series Spherical Roller Bearings. With precise dimensions of 100mm bore diameter, 215mm outer diameter, and 47mm thickness, this bearing is engineered to deliver exceptional reliability and longevity in demanding industrial applications. Spherical roller bearings are uniquely designed with two rows of rollers and a common spherical raceway in the outer ring, along with two inner ring raceways inclined at an angle to the bearing axis. This configuration enables the bearing to accommodate not only heavy radial loads but also significant axial loads in both directions. Crucially, the 21320 bearing boasts excellent self-aligning capabilities, making it highly tolerant to angular misalignment of the shaft relative to the housing, a common challenge in many heavy-duty machines.
As a leading supplier of industrial bearings and mechanical parts, we ensure that our 21320 spherical roller bearings are manufactured to rigorous industry standards. Their robust construction and optimized internal geometry provide superior performance, high shock resistance, and extended operational life, even under harsh operating conditions and heavy vibrations. This makes the 21320 an indispensable choice for critical applications where reliability and consistent operation are paramount. Explore our comprehensive selection of spherical roller bearings to find the ideal solution for your specific industrial requirements.
