Product Overview: The 22216 Spherical Roller Bearing
The 22216 bearing is a high-capacity, double-row, self-aligning roller bearing designed for the most demanding industrial applications. With key dimensions of 80mm bore diameter, 140mm outer diameter, and 33mm thickness, this bearing is a crucial component in our 22200 Series of Spherical Roller Bearings. Its design features two rows of symmetrical barrel rollers and a common sphered raceway in the outer ring. This unique construction allows the bearing to tolerate significant angular misalignment of the shaft relative to the housing, as well as shaft deflection during operation, without compromising performance.
Engineered to accommodate heavy radial loads and moderate axial loads in both directions, the 22216 is the ideal choice for machinery operating in harsh environments where shock loads and vibrations are prevalent. As a leading supplier of industrial components, we ensure our spherical roller bearings meet stringent quality standards for reliability and long service life.
Key Features of the 22216 Bearing
- Self-Aligning Capability: The spherical outer raceway allows for compensation of dynamic and static misalignment, reducing stress on the bearing and extending machine life.
- High Load Capacity: The double-row roller design provides excellent capacity for carrying heavy radial and bi-directional axial loads.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and resistance to wear and fatigue.
- Optimized Internal Design: Engineered for low friction and reduced operating temperatures, enhancing efficiency and service life.
- Versatile Mounting: Typically available with a cylindrical bore for straightforward press-fitting onto a shaft.
- Dimensional Stability: Precision manufacturing ensures consistent dimensions for easy interchangeability and reliable fitting.
Common Applications
- Mining and Construction: Widely used in crushers, vibrating screens, conveyor systems, and heavy-duty gearboxes.
- Pulp and Paper Industry: Essential for paper machine rollers, calenders, and press sections.
- Industrial Gearboxes: Provides reliable support for gears and shafts in large industrial transmissions.
- Wind Turbines: Used in main shafts and gearboxes to handle the immense and variable loads.
