Product Overview: The 22217 Spherical Roller Bearing
The 22217 is a high-performance Spherical Roller Bearing, an essential component in our 22200 Series. With principal dimensions of 85mm Bore Diameter, 150mm Outer Diameter, and 36mm Thickness, this bearing is engineered to excel in the most demanding industrial environments. Its core design feature is the ability to handle severe misalignment between the shaft and housing, making it indispensable for applications with shaft deflection or mounting errors. The bearing contains two rows of symmetrical barrel-shaped rollers that align themselves freely within a common sphered raceway in the outer ring, ensuring optimal performance under heavy radial and moderate axial loads in both directions. As a key part of our Spherical Roller Bearings catalog, the 22217 offers unparalleled reliability and service life.
Features of the 22217 Bearing
- Self-Aligning Capability: Automatically compensates for angular misalignment, reducing stress on the shaft and extending the bearing's operational life.
- High Load Capacity: Designed with two rows of rollers to support very heavy radial loads and significant axial loads from either direction.
- Robust Construction: Manufactured from high-quality bearing steel for superior durability, wear resistance, and performance in harsh conditions.
- Symmetrical Barrel Rollers: The roller geometry ensures optimal load distribution and minimizes friction, even under misalignment.
- Versatile Bore Options: Typically available with a cylindrical bore for standard mounting or a tapered bore for use with adapter sleeves like the H 317.
- Optimized for Heavy Industry: Engineered to withstand shock loads, vibrations, and challenging operational environments.
