S7007 CDGA/P4A Bearing Product Overview & Core Advantages
The S7007 CDGA/P4A is a precision angular contact ball bearing designed for high-performance applications requiring exceptional rotational accuracy and rigidity. As a single bearing with Universal Matchable (SU) designation, it can be paired with identical bearings in various arrangements to achieve optimal preload and system stiffness. Its P4A tolerance class ensures superior dimensional and running accuracy, making it ideal for high-speed operation and applications demanding minimal runout. The combination of a 15° contact angle and extra light preload (Class A) provides excellent performance for combined radial and axial loads.

S7007 CDGA/P4A Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4A tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring minimal vibration and exceptional running accuracy for precision applications.
Optimized Load Capacity: The 15° contact angle enables efficient handling of combined radial and axial loads, with dynamic load rating of 3510 lbf and static load rating of 2138 lbf.
High-Speed Performance: The phenolic resin cage provides excellent strength-to-weight ratio, contributing to the high limiting speed of 56,000 rpm while reducing centrifugal forces.
Premium Material Selection: Constructed from chrome steel for both rings and balls, offering high hardness, wear resistance, and dimensional stability under varying operating conditions.
Universal Matching Capability: As a Universal Matchable (SU) bearing, it can be supplied in sets of 3 for precise preload control in back-to-back, face-to-face, or tandem arrangements.
