The 22200, 22300, and 21300 Series Spherical Roller Bearings are versatile and high-capacity bearings designed to handle heavy radial and axial loads in demanding industrial environments. With a self-aligning design, these bearings efficiently compensate for misalignment, ensuring smooth operation in applications such as heavy machinery, mining, and power generation.
Features:
- Spherical Roller Design: Dual-row configuration offers superior load distribution for heavy-duty applications.
- Self-Aligning Capability: Automatically compensates for shaft misalignment and deflection.
- High Load Capacity: Handles significant radial loads and moderate axial loads in both directions.
- Durable Materials: Made from premium-grade steel for wear resistance and extended lifespan.
- Low Friction Operation: Optimized cage design reduces heat and friction for efficient performance.
- Lubrication-Friendly: Compatible with grease and oil; raceways facilitate smooth lubricant flow.
- Versatile Applications: Suitable for both fixed and floating bearing arrangements.
- Robust Design: Thick outer ring and precise rollers enhance reliability under dynamic conditions.
Applications:
- Steel Mills: Used in rolling mills, continuous casting machines, and gearboxes.
- Mining and Quarrying: Reliable in crushers, conveyors, and other heavy-duty equipment.
- Power Generation: Ideal for turbines, generators, and large mechanical systems.
- Construction Equipment: Found in cranes, excavators, and heavy machinery.
- Pulp and Paper Industry: Supports high loads in drying cylinders and rollers.
