Product Overview: The 21310 Spherical Roller Bearing
The 21310 Spherical Roller Bearing is a high-capacity, self-aligning component engineered for the most demanding industrial applications. With dimensions of 50mm bore diameter, 110mm outer diameter, and 27mm thickness, this bearing is part of the robust 21300 Series within our extensive range of Spherical Roller Bearings. Its design features two rows of symmetrical barrel-shaped rollers in a common sphered outer ring raceway, which allows it to accommodate significant shaft misalignment and heavy radial and axial loads in both directions. This inherent self-alignment capability makes the 21310 an indispensable solution for machinery where shaft deflection or mounting errors are a concern.
Key Features of the 21310 Bearing
- Self-Aligning Capability: Automatically compensates for angular misalignment between the shaft and housing, reducing stress on the bearing and extending machine life.
- High Load Capacity: Engineered to support very heavy radial loads and significant axial loads in both directions, making it ideal for heavy-duty machinery.
- Robust Construction: Manufactured from high-quality bearing steel for exceptional durability, wear resistance, and performance in harsh operating conditions.
- Two-Row Roller Design: Features two rows of symmetrical barrel rollers for optimal load distribution and enhanced operational stability.
- Low Friction Operation: Precision-engineered internal geometry minimizes friction and heat generation, ensuring efficient performance and longevity.
- Cylindrical Bore: Designed for straightforward mounting on a cylindrical shaft seat.
