Product Overview: The 22240 Spherical Roller Bearing
The 22240 Spherical Roller Bearing is a high-capacity, double-row, self-aligning bearing designed for the most demanding industrial applications. With principal dimensions of 200x360x98mm (Bore x Outer Diameter x Thickness), this robust component is part of our 22200 Series of Spherical Roller Bearings. Its key design feature is the spherical outer ring raceway, which allows the bearing to accommodate significant angular misalignment of the shaft relative to the housing. This makes the 22240 bearing an ideal solution for machinery where shaft deflection or mounting errors are unavoidable.
Manufactured from high-quality bearing steel, the 22240 is engineered to support very high radial loads and moderate axial loads in both directions. It is commonly found in heavy machinery, providing exceptional reliability and a long service life even under severe operating conditions, including heavy loads, shock, and vibration. Explore our complete range of spherical roller bearings to find the optimal solution for your heavy-duty industrial needs.
Key Features of the 22240 Bearing
- Self-Aligning Capability: The spherical raceway in the outer ring compensates for dynamic and static misalignment, reducing stress on the shaft and extending machine life.
- High Radial Load Capacity: Features two rows of symmetrical barrel rollers, providing excellent capacity for heavy radial loads.
- Axial Load Support: Capable of supporting moderate axial loads in both directions, offering versatile application potential.
- Robust Construction: Made from premium-grade bearing steel for superior durability, wear resistance, and performance in harsh environments.
- Optimized Internal Design: Engineered for low friction and efficient roller guidance, minimizing heat generation and ensuring smooth operation.
- Lubrication Features: Typically designed with a lubrication groove and holes in the outer ring to facilitate effective relubrication and prolong service life.
Common Applications
- Mining and Construction: Used in heavy equipment such as rock crushers, vibrating screens, and conveyor systems where high loads and misalignment are common.
- Pulp and Paper Mills: Ideal for machinery like press sections, calenders, and drying cylinders that operate under extreme conditions.
- Steel Manufacturing: Essential for continuous casters, rolling mills, and other high-temperature, high-load applications.
