Product Overview: The 22311 Spherical Roller Bearing
The 22311 Spherical Roller Bearing is a high-capacity, self-aligning bearing designed for the most demanding industrial applications. With dimensions of 55x120x43mm, this robust component is a key part of our 22300 Series and the broader Spherical Roller Bearings collection. Its unique internal design, featuring two rows of symmetrical barrel-shaped rollers in a common sphered outer ring raceway, allows it to accommodate significant shaft misalignment and deflection. This makes the 22311 bearing exceptionally reliable in machinery where perfect alignment is difficult to achieve or maintain.
Engineered to handle very heavy radial and substantial axial loads in both directions, the 22311 is manufactured from high-purity, hardened bearing steel to ensure superior durability and an extended service life. It is the go-to solution for heavy-duty machinery operating in harsh environments, providing smooth, low-friction performance and minimizing maintenance requirements. Explore our comprehensive range to find the perfect bearing solution for your heavy industrial needs.
Key Features of the 22311 Bearing
- Excellent Misalignment Compensation: The spherical raceway design allows the bearing to self-align, compensating for angular errors between the shaft and housing.
- High Load-Carrying Capacity: Engineered with two rows of rollers to support extremely high radial loads and significant axial loads from either direction.
- Robust Construction: Manufactured from premium-grade, through-hardened steel for maximum toughness, wear resistance, and operational longevity.
- Low-Friction Operation: The roller geometry is optimized to reduce friction and heat generation, ensuring efficient performance even at high speeds.
- Dimensional Stability: Precision-engineered to strict industry standards, ensuring consistent fit and reliable performance under heavy loads.
- Versatile Mounting Options: Available with a cylindrical bore for standard press fits or a tapered bore for mounting with an adapter sleeve on a plain shaft.
Common Applications
- Mining and Construction: Widely used in rock crushers, vibrating screens, conveyor systems, and heavy earth-moving equipment.
- Pulp and Paper Mills: Essential for rollers in press sections, calendars, and other high-load machinery.
- Industrial Gearboxes: Provides reliable support for gears and shafts in large-scale power transmission systems.
