S7013 CDGB/P4A Bearing Product Overview & Core Advantages
The S7013 CDGB/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. Manufactured to P4A tolerance class, this bearing delivers superior dimensional stability and running precision. Its 15° contact angle and universal matching (SU) capability enable it to handle combined radial and axial loads efficiently. The phenolic cage and factory-applied grease lubrication contribute to its high-speed capabilities with a limiting speed of 36,000 rpm, making it ideal for precision spindles and high-rotation equipment requiring minimal vibration and maximum reliability.
