Product Overview: The 22212 Spherical Roller Bearing
The 22212 is a high-capacity spherical roller bearing, meticulously engineered to perform in the most demanding industrial environments. As a key component in our 22200 Series of Spherical Roller Bearings, it features a robust design with two rows of symmetrical barrel rollers. This construction, combined with a common sphered outer ring raceway, allows the bearing to accommodate significant shaft misalignment and deflection without compromising performance. Its dimensions of 60mm bore diameter, 110mm outer diameter, and 28mm thickness make it suitable for a wide range of heavy-duty applications requiring exceptional load-carrying capabilities.
Built to industry-standard specifications, the 22212 bearing is designed to handle very heavy radial loads and moderate axial loads in both directions. The internal design ensures optimal roller guidance and load distribution, minimizing friction and heat generation, which contributes to a longer service life. This bearing is an essential solution for industries where reliability and durability are paramount.
Key Features of the 22212 Bearing
- Self-Aligning Capability: Automatically compensates for angular misalignment between the shaft and housing, reducing stress on the bearing and machinery.
- High Load Capacity: Engineered with two rows of rollers to support extremely high radial loads and substantial axial loads.
- Robust Construction: Manufactured from high-quality, clean bearing steel for maximum durability and resistance to wear and fatigue.
- Optimized Internal Design: Ensures superior load distribution and roller guidance for smooth, low-friction operation.
- Lubrication Features: Typically designed with a lubrication groove and holes in the outer ring to facilitate effective relubrication and extend service life.
- Dimensional Stability: Heat-treated to operate reliably across a wide range of temperatures without significant dimensional changes.
Common Applications
- Mining and Construction: Ideal for crushers, vibrating screens, conveyor systems, and heavy earth-moving equipment.
