S7012 CD/P4ADGB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with 15° contact angle enables the bearing to simultaneously handle substantial radial loads and axial loads in both directions. The universal matched pair arrangement provides optimal load distribution and enhanced system stiffness.
Precision Performance: Manufactured to P4A tolerance class with tight dimensional tolerances (bore: -0.004mm to 0, OD: -0.004mm to 0), ensuring exceptional running accuracy and minimal vibration for precision applications.
High-Speed Capability: The phenolic cage contributes to reduced friction and higher limiting speeds (31,000 rpm), while the optimized grease lubrication ensures stable performance at elevated rotational speeds.
Maintenance-Free Operation: The sealed design with factory-applied grease provides long-term lubrication, protecting against contamination and extending service life without requiring re-lubrication.
