7013 ACE/P4ADGA Bearing Product Overview & Core Advantages
The 7013 ACE/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Engineered with an Extra light preload (Class A) and manufactured to P4A tolerance class, this bearing delivers superior rotational precision and dimensional stability. Its 25° contact angle is optimized to support combined loads, efficiently handling significant axial loads in one direction alongside radial loads. The Universal Matchable (SU) design allows for flexible mounting in pairs to accommodate bidirectional axial loads, making it a compact and versatile solution for high-performance machinery.

7013 ACE/P4ADGA Bearing Structural Features & Performance Benefits
High Precision & Rigidity: Manufactured to P4A tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring minimal runout and vibration. The Extra light preload (Class A) eliminates internal clearance, providing superior stiffness and positional accuracy.
Optimized Load Capacity: The 25° contact angle and robust construction enable high radial dynamic load rating (7020 lbf) and static load rating (6525 lbf), making it ideal for applications with significant combined loads.
High-Speed Performance: The phenolic cage and precision-ground chrome steel components contribute to a high limiting speed of 31,000 rpm, suitable for demanding high-speed applications.
Universal Matching Capability: As a Universal Matchable (SU) bearing supplied in a matched pair, it can be arranged in back-to-back (DB) or face-to-face (DF) configurations to handle bidirectional axial loads and moments.
