7012 ACE/P4BVG275 Bearing Product Overview & Core Advantages
The 7012 ACE/P4BVG275 is a single-row angular contact ball bearing designed for applications requiring high precision and superior rotational accuracy. Engineered to accommodate primarily axial loads in one direction, this bearing features a 25° contact angle and P4 (ABEC-7) tolerance class for exceptional running accuracy. Its phenolic resin cage and preload availability make it ideal for high-speed applications where rigidity and minimal vibration are critical. The bearing comes pre-lubricated for immediate installation and reliable operation.

| Code Segment | Technical Meaning |
|---|---|
| 7012 | Basic bearing designation (60mm bore, 95mm OD, 18mm width) |
| ACE | 25° contact angle design with optimized internal geometry |
| P4 | High precision tolerance class (equivalent to ABEC-7) |
| BVG275 | Specific internal design code including cage type and lubrication |
7012 ACE/P4BVG275 Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4 tolerance class with bore diameter tolerance of -0.007mm to 0 and outside diameter tolerance of -0.008mm to 0, ensuring exceptional dimensional stability and running accuracy.
Optimized Contact Angle: The 25° contact angle provides excellent axial load capacity while maintaining good radial load performance, making it suitable for combined loading conditions.
High-Speed Capability: The phenolic resin cage offers excellent strength-to-weight ratio, contributing to the high limiting speed of 18,000 rpm. The cage design minimizes friction and allows for efficient lubrication distribution.
Superior Material Quality: Both rings and balls are made from high-grade chrome steel, providing excellent wear resistance and fatigue life. The bearing can operate within a temperature range of -30°C to 110°C.
Preload Availability: The bearing is designed to accommodate preload, enabling higher system stiffness and improved rotational accuracy for demanding applications.
