Product Overview: The 22334 Spherical Roller Bearing
The 22334 bearing is a high-capacity, double-row spherical roller bearing engineered to excel in the most demanding industrial environments. With its principal dimensions of 170mm bore diameter, 360mm outer diameter, and 120mm width, this bearing is part of the robust 22300 Series. It is specifically designed to handle very heavy radial loads and significant axial loads in both directions. The key feature of Spherical Roller Bearings is their ability to accommodate severe misalignment between the shaft and housing, making them indispensable in applications where shaft deflection or mounting errors are a concern.
Manufactured from premium-grade steel, the 22334 bearing ensures exceptional durability and a long service life. Its internal design, featuring two rows of symmetrical barrel rollers, allows for smooth operation and optimal load distribution, even under conditions of high shock and vibration. This makes it a reliable choice for heavy machinery across various sectors.
Key Features of the 22334 Bearing
- Superior Load Capacity: Engineered with two rows of rollers to support extremely high radial and substantial axial loads.
- Self-Aligning Capability: The spherical raceway in the outer ring allows the bearing to compensate for angular misalignment and shaft deflection.
- Heavy-Duty Construction: Made from high-purity, hardened bearing steel for maximum wear resistance and toughness in harsh conditions.
- Robust Roller Design: Symmetrical barrel rollers provide optimal load distribution along the roller length, reducing stress and extending operational life.
- Enhanced Durability: Designed to perform reliably under heavy shock loads, vibration, and challenging operating speeds.
- Versatile Mounting Options: Typically available with a cylindrical or tapered bore (K suffix) to be used with adapter sleeves like the H 2334 for easy mounting.
Common Applications
- Mining and Quarrying: Widely used in rock crushers, vibrating screens, conveyor systems, and grinding mills.
- Steel and Metal Processing: Essential for continuous casters, rolling mill stands, and gearbox applications.
- Pulp and Paper Industry: Found in paper machine rollers, calenders, and pulp processing equipment.
- Construction Machinery: Critical component in heavy earth-moving equipment, cranes, and large gearboxes.
- Wind Energy: Used in wind turbine main shafts and gearboxes where reliability under heavy, fluctuating loads is vital.
- Marine and Offshore: Applied in propulsion systems, winches, and rudder stocks.
- Industrial Fans and Blowers: Provides robust support for large-scale ventilation systems operating under demanding conditions.
Benefits of Using the 22334 Bearing
