7024 CD/P4ATBTA Bearing Structural Features & Performance Benefits
High Rigidity & Stability: The triplex back-to-back configuration creates a rigid bearing system that minimizes deflection under load, crucial for maintaining precision in machining operations. The 15° contact angle provides optimal load distribution for combined loading conditions.
Exceptional Precision: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, ensuring minimal runout and vibration for superior rotational accuracy.
Optimized Component Design: Features phenolic resin cage for reduced weight and improved high-speed capability, with 22 chrome steel balls of 19.05mm diameter providing high load capacity. The extra light preload eliminates internal clearance while maintaining low operating torque.
High-Speed Performance: With a limiting speed of 16,000 rpm and optimized internal geometry, this bearing set delivers reliable performance in high-speed spindle applications.
