Description
SKF 22216 EK/C3 — Spherical Roller Bearing
Overview
The SKF 22216 EK/C3 is a high-performance spherical roller bearing designed for heavy-duty industrial applications. It can accommodate high radial loads and moderate axial loads in both directions, while tolerating misalignment between shaft and housing. Its C3 internal clearance and relubrication features make it ideal for high-temperature and intensive operational environments.
Key Features
-
Type: Spherical roller bearing, two rows of rollers
-
Internal Clearance: C3 (greater than standard for thermal expansion)
-
Cage: Pressed sheet metal for improved roller guidance
