S7009 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: Manufactured to a P4 tolerance class with a 15° contact angle and preload, this bearing provides exceptional shaft positioning accuracy and system stiffness, minimizing deflection under load.
- Superior Load Capacity: The angular contact design efficiently handles combined radial and axial loads simultaneously. With a dynamic load rating of 2925 lbf and a static load rating of 1912 lbf, it offers reliable performance in demanding applications.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 27,000 rpm. The sealed design helps retain lubrication and exclude contaminants.
- Ready-to-Use & Durable: The bearing comes pre-lubricated and is constructed from chrome steel for both rings and balls, ensuring high durability and a long service life within its specified temperature range of -30°C to 110°C.
