7210 CD/P4ADGC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with 15° contact angle provides excellent resistance to combined loads, while the moderate preload (Class C) ensures stable operation under varying load conditions. With a dynamic load rating of 16,380 lbf and static load rating of 15,300 lbf, this bearing offers reliable performance in demanding applications.
Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional tolerances (bore: -0.004mm to 0, OD: -0.004mm to 0), this bearing delivers exceptional running accuracy and minimal vibration. The phenolic cage provides excellent strength-to-weight ratio and smooth operation at high speeds.
High-Speed Performance: Capable of operating at 41,000 rpm limiting speed, the bearing features optimized internal geometry and 15 chrome steel balls (12.7mm diameter) for balanced rotational characteristics. The open design allows for efficient lubrication management in high-speed applications.
Universal Matching Capability: As a Universal Matchable (SU) bearing, two units can be paired in various configurations (back-to-back, face-to-face, or tandem) to create optimized bearing arrangements for specific application requirements.
