Product Overview: The 21322 Spherical Roller Bearing
The 21322 Spherical Roller Bearing is a high-capacity component engineered for the most demanding industrial applications. With core dimensions of 110mm Bore Diameter, 240mm Outer Diameter, and 50mm Thickness, this bearing is part of our robust 21300 Series within the Spherical Roller Bearings category. Its design features two rows of symmetrical barrel rollers and a common sphered raceway in the outer ring. This unique construction allows the bearing to tolerate significant angular misalignment of the shaft relative to the housing, making it indispensable in machinery where shaft deflection or mounting errors are a concern.
Built to handle very heavy radial and axial loads in both directions, the 21322 bearing provides exceptional reliability and a long service life even under harsh operating conditions. It is a fundamental component in heavy machinery, ensuring smooth and efficient operation where strength and adaptability are paramount.
Key Features of the 21322 Bearing
- Excellent Misalignment Compensation: The internal design automatically compensates for angular misalignment and shaft deflection, reducing stress on the application.
- High Load-Carrying Capacity: Engineered to support extremely high radial loads and significant axial loads in both directions, making it ideal for heavy-duty use.
- Robust Construction: Manufactured from high-quality, ultra-clean steel to maximize service life and resist wear in contaminated environments.
- Two Rows of Symmetrical Rollers: The double-row design provides superior load distribution and operational stability.
- Optimized for Performance: Designed for low friction and minimal heat generation, contributing to operational efficiency and longevity.
- Versatile Mounting Options: Available with a cylindrical bore for standard press fits or a tapered bore for mounting with adapter or withdrawal sleeves like the H 322.
