7013 ACD/P4AQBCDGMM Bearing Product Overview & Core Advantages
The 7013 ACD/P4AQBCDGMM is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing, it can be paired with another identical bearing in various configurations to optimize preload and system performance. Its key advantages include the ability to handle combined loads (radial and axial), high limiting speed capabilities, and superior running accuracy due to its P4A tolerance class. This makes it an ideal solution for high-precision, high-reliability machinery.

7013 ACD/P4AQBCDGMM Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The optimized internal geometry and 25° contact angle enable the bearing to support significant combined loads. The universal matchable (SU) design allows for precise preload control when mounted in pairs, further enhancing system stiffness.
High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, contributing to the high limiting speed of 31,000 rpm. This makes it suitable for high-speed applications.
Precision & Longevity: Manufactured to a P4A tolerance class, this bearing ensures minimal runout and vibration for superior positional accuracy. The chrome steel rings and balls provide excellent wear resistance and long service life.
Pre-Lubrication: The bearing is pre-lubricated with grease, suitable for a temperature range of -30°C to 110°C, ensuring immediate operation and protection during the run-in period.
