S7001 CE/P4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double-row angular contact design provides superior radial and axial stiffness, enabling stable performance under combined loading conditions. With a 15° contact angle, the bearing efficiently handles bidirectional axial loads while maintaining excellent rotational precision.
Precision Engineering: Manufactured to P4A tolerance standards with bore diameter tolerance of -0.004mm to 0 and outside diameter tolerance of -0.004mm to 0, ensuring consistent performance in demanding applications. The phenolic cage material offers excellent dimensional stability and reduced weight.
High-Speed Capability: Featuring a limiting speed of 95,000 rpm, the bearing is optimized for high-velocity applications. The combination of precision-ground chrome steel components and optimized internal geometry minimizes friction and heat generation.
Maintenance-Free Operation: The sealed construction with factory-applied grease lubrication provides long-term protection against contamination and ensures reliable performance throughout the bearing's service life within the operating temperature range of -30°C to 110°C.
