7001 CDGC/P4A Bearing Product Overview & Core Advantages
The 7001 CDGC/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring superior rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing delivers exceptional dimensional stability and running accuracy. Its 15° contact angle provides optimal performance for combined loads, particularly excelling in handling thrust loads in one direction while accommodating radial loads. The phenolic resin cage ensures smooth operation at high speeds, while the universal matching (SU) designation allows for precise preload configuration when mounted in pairs. This bearing comes pre-lubricated for immediate installation and reliable performance.

7001 CDGC/P4A Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4A tolerance standards with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring exceptional running accuracy and minimal vibration in precision applications.
Optimized Load Capacity: The 15° contact angle design provides excellent performance for combined loads, with a dynamic load rating of 1010 lbf and static load rating of 428 lbf, making it suitable for applications requiring both radial and axial load support.
High-Speed Capability: The phenolic resin cage combined with optimized internal geometry enables operation at limiting speeds up to 100,000 rpm, while maintaining stability and reducing friction at high rotational velocities.
Universal Matching Design: As a universal matchable bearing (SU), the 7001 CDGC/P4A can be precisely paired with another identical bearing to achieve specific preload conditions (Moderate / Class C), enhancing system rigidity and positioning accuracy.
Premium Material Selection: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and durability, while operating effectively within a temperature range of -30°C to 110°C.
