7215 CDGC/P4A Bearing Product Overview & Core Advantages
The 7215 CDGC/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. As a single bearing with moderate preload (Class C), it delivers optimized performance for combination loads while maintaining precise shaft positioning. Manufactured to P4A tolerance class, this bearing ensures superior running accuracy and is universally matchable (SU), allowing for flexible arrangement in sets to achieve specific preload and stiffness requirements. Its 15° contact angle provides an excellent balance between radial and axial load capacity.

7215 CDGC/P4A Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with moderate preload provides superior stiffness, effectively resisting combination loads (simultaneous radial and axial forces). With a dynamic load rating of 16,088 lbf and static load rating of 13,950 lbf, it delivers reliable performance under significant operational stresses.
Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring minimal runout and vibration for high-precision applications.
Optimized High-Speed Performance: The phenolic cage provides excellent strength-to-weight ratio, contributing to lower inertial forces and enabling limiting speeds up to 22,000 rpm. The 15° contact angle further enhances high-speed capability.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, delivering high hardness, wear resistance, and dimensional stability across the operating temperature range of -30°C to 110°C.
