Product Overview: The 22330 Spherical Roller Bearing
The 22330 Spherical Roller Bearing is a high-capacity, robust component engineered for the most demanding industrial applications. As a key part of our 22300 Series of Spherical Roller Bearings, this bearing features a 150mm bore diameter, 320mm outer diameter, and 108mm thickness. Its design includes two rows of symmetrical barrel-shaped rollers that rotate within a common sphered outer ring raceway. This configuration allows the bearing to accommodate significant angular misalignment of the shaft relative to the housing, making it indispensable in machinery where shaft deflection or mounting errors are a concern.
Manufactured to stringent industry standards, the 22330 bearing is designed to handle very heavy radial loads and moderate axial loads in both directions. Its internal design ensures low friction and optimal roller guidance, contributing to a long service life even under harsh operating conditions. This makes it a reliable choice for heavy industries seeking to minimize downtime and enhance machine performance.
Key Features of the 22330 Bearing
- Superior Load Capacity: Engineered with two rows of rollers to support extremely high radial and moderate bidirectional axial loads.
- Self-Aligning Capability: The spherical outer raceway allows for compensation of both static and dynamic angular misalignment.
- Robust Construction: Made from high-purity, through-hardened bearing steel for exceptional durability and wear resistance.
- Optimized Internal Design: Ensures low friction during operation, reducing heat generation and extending bearing life.
- High Dimensional Stability: Precision manufacturing guarantees consistent performance and interchangeability.
- Versatile Mounting: Available with a cylindrical bore for direct shaft mounting or a tapered bore for use with adapter sleeves like the H 2330.
Common Applications
- Mining and Construction: Widely used in rock crushers, vibrating screens, conveyors, and heavy earth-moving equipment.
- Pulp and Paper Industry: Essential for rollers in paper machines, calenders, and pulp processing equipment.
