S71914 CE/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Design: The use of ceramic balls significantly reduces centrifugal forces, lowers operating temperature, and provides excellent electrical insulation, contributing to superior high-speed capability and extended service life.
- High Rigidity & Precision: The 15° contact angle and applied preload ensure high system stiffness and minimal axial/radial runout, which is critical for maintaining precision in machining and positioning applications.
- Optimized High-Speed Performance: The lightweight phenolic resin cage offers high strength and excellent sliding properties, enabling stable operation at the limiting speed of 22,000 rpm.
- Superior Load Capacity: With a dynamic load rating of 4972 lbf and a static load rating of 3600 lbf, this bearing reliably handles significant combined loads.
- Sealed & Lubricated: The bearing is supplied sealed and pre-lubricated, protecting against contamination and providing maintenance-free operation within its specified temperature range.
S71914 CE/HCP4A Bearing Typical Application Areas
