Key Design & Performance Features
- E-Type Optimized Internal GeometryThe E-type design features a reinforced inner ring, optimized roller profiles, and a streamlined cage structure. This reduces internal friction and heat generation, while enhancing the bearing’s ability to withstand high radial loads and moderate bidirectional axial loads over extended service life.
- C3 Increased Radial ClearanceRated with C3 radial internal clearance, this bearing is specifically designed for applications with high operating temperatures or significant thermal expansion of shafts/housings. The increased clearance prevents premature seizure and ensures smooth rotation even under extreme thermal conditions.
- Excellent Self-Aligning CapabilityA core advantage of spherical roller bearings, the 22220E/C3 can compensate for angular misalignment (up to 2°) between the shaft and housing. This feature minimizes stress on the bearing and adjacent components, reducing wear and lowering long-term maintenance costs.
- High-Quality Material & DurabilityManufactured from SKF’s high-purity bearing steel, the bearing undergoes advanced heat treatment processes to deliver superior wear resistance, fatigue strength, and impact resistance—even in harsh, contaminated environments.
- Versatile Lubrication CompatibilityCompatible with both grease and oil lubrication systems, it adapts to diverse operating environments, from low-speed heavy-load applications to high-speed continuous operations.
