V7012 CEGA/P4A Bearing Product Overview & Core Advantages
The V7012 CEGA/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional running accuracy and rigidity. Manufactured to P4A tolerance class with an extra light preload (Class A), this bearing delivers superior rotational precision and minimal deflection under load. Its 15° contact angle optimizes performance for combined loads, effectively handling both radial and significant axial loads in one direction. The phenolic cage and universal matching capability (SU) make it ideal for precision spindle arrangements requiring high-speed operation and thermal stability.

V7012 CEGA/P4A Bearing Structural Features & Performance Benefits
High Precision Construction: The V7012 CEGA/P4A features chrome steel rings and balls with P4A tolerance classification, ensuring exceptional dimensional stability and running accuracy. The phenolic resin cage provides excellent dimensional stability at high speeds while reducing friction and weight.
Optimized Load Capacity: With a 15° contact angle and precision-ground raceways, this bearing efficiently handles combined radial and axial loads. The radial dynamic load rating of 3870 lbf and static load rating of 2902 lbf demonstrate its robust load-carrying capability in compact dimensions.
High-Speed Performance: The phenolic cage and optimized internal geometry enable operation at limiting speeds up to 31,000 rpm, making it suitable for high-speed spindle applications. The universal matching capability (SU) allows for precise preload control in multi-bearing arrangements.
Precision Engineering: Tight dimensional tolerances (bore: -0.004mm to 0, OD: -0.004mm to 0) ensure consistent performance and easy installation in precision machinery.
