Product Overview: The 22222 Spherical Roller Bearing
The 22222 Spherical Roller Bearing is a high-capacity, self-aligning bearing engineered for the most demanding industrial applications. With principal dimensions of 110mm bore diameter, 200mm outer diameter, and 53mm thickness, this component is a key part of our 22200 Series within the broader Spherical Roller Bearings collection. Its design features two rows of symmetrical barrel-shaped rollers and a common sphered raceway in the outer ring. This configuration allows the bearing to accommodate significant angular misalignment of the shaft relative to the housing, as well as shaft deflection under load, without compromising performance.
Built to withstand extreme conditions, the 22222 bearing excels at handling very high radial loads and moderate axial loads in both directions. It is the preferred choice for heavy machinery where reliability and longevity are critical. As a leading supplier of industrial components, we provide top-quality bearings that meet rigorous industry standards, ensuring your equipment operates smoothly and efficiently.
Key Features of the 22222 Bearing
- Excellent Misalignment Compensation: The spherical internal design allows for self-alignment, reducing stress on the bearing and increasing service life in applications with shaft deflection.
- High Radial Load Capacity: Two rows of barrel rollers provide a large contact area, enabling the bearing to support very heavy radial loads.
- Bidirectional Axial Load Support: Capable of accommodating axial loads in both directions, making it versatile for complex loading scenarios.
- Robust and Durable Construction: Manufactured from high-purity, through-hardened bearing steel for exceptional toughness and wear resistance.
- Optimized for Heavy-Duty Use: Designed to perform reliably in harsh environments characterized by heavy loads, vibration, and contamination.
- Low-Friction Operation: The roller and raceway geometry is optimized to minimize friction and heat generation, enhancing operational efficiency.
Common Applications
- Mining and Construction: Widely used in rock crushers, vibrating screens, conveyors, and other heavy-duty machinery.
- Pulp and Paper Mills: Essential for calendar rolls, press sections, and other equipment operating under high loads and wet conditions.
- Industrial Gearboxes: Provides reliable support for gears and shafts in large industrial transmissions, ensuring smooth power transfer.
- Wind Turbines: Used in the main shafts and gearboxes of wind energy converters to handle immense and fluctuating loads.
