Key Design & Performance Features
- E-Type Optimized Internal GeometryThe E-type design incorporates a reinforced inner ring, precision-machined roller profiles, and a streamlined pressed steel cage. This configuration minimizes internal friction and heat generation, while boosting the bearing’s capacity to withstand extreme radial loads and moderate bidirectional axial loads over an extended service life.
- C3 Increased Radial ClearanceRated with C3 radial internal clearance, this bearing is specifically tailored for applications with high operating temperatures or significant thermal expansion of shafts and housings. The enhanced clearance prevents premature seizure and ensures smooth rotation even under fluctuating thermal conditions.
- Superior Self-Aligning CapabilityA core advantage of spherical roller bearings, the 22222E/C3 can compensate for angular misalignment of up to 2° between the shaft and housing. This feature reduces stress on the bearing and adjacent components, minimizing wear and lowering long-term maintenance costs.
- High-Quality Material & DurabilityManufactured from SKF’s high-purity vacuum-degassed bearing steel, the 22222E/C3 undergoes advanced heat treatment processes. This results in exceptional wear resistance, fatigue strength, and impact resistance, even in harsh, contaminated industrial environments.
- Versatile Lubrication CompatibilityThe bearing is compatible with both grease and oil lubrication systems, making it adaptable to a wide range of operating conditions—from low-speed, heavy-load applications to high-speed, continuous-duty operations.
Typical Applications
The SKF 22222E/C3 is widely used across key industrial sectors where heavy loads and reliable performance are critical:
