S7013 CEGA/P4A Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design and precision-ground chrome steel components enable the bearing to support significant combined radial and axial loads simultaneously. The optimized internal geometry ensures high system rigidity.
Superior High-Speed Performance: The lightweight phenolic resin cage minimizes centrifugal forces and friction, enabling a high limiting speed of 36,000 rpm. The 15° contact angle is optimized for high-speed operation with low heat generation.
Precision & Longevity: Manufactured to P4A tolerance class, this bearing guarantees exceptional running accuracy. The sealed design retains factory-applied grease, protecting against contamination and providing a long, maintenance-free service life within its specified temperature range of -30°C to 110°C.
