7017 ACDGC/P4A Bearing Product Overview & Core Advantages
The 7017 ACDGC/P4A is a single-row angular contact ball bearing engineered for applications demanding high precision and superior rotational accuracy. Manufactured to P4A tolerance class, this bearing delivers exceptional dimensional stability and running accuracy. Its 25° contact angle is optimized to support significant combined loads, handling both radial and axial loads simultaneously. The phenolic cage and factory-applied lubrication contribute to its high-speed capability and reliable performance in demanding operational conditions.

7017 ACDGC/P4A Bearing Structural Features & Performance Benefits
Precision Engineering: The P4A tolerance class ensures minimal runout and vibration, making it ideal for high-precision applications. The tight dimensional tolerances (-0.004mm to 0 on bore and OD) guarantee consistent performance.
Optimized Load Capacity: With a 25° contact angle, this bearing effectively handles combined radial and axial loads. The radial dynamic load rating of 14,332 lbf and static load rating of 13,950 lbf provide robust performance under demanding conditions.
High-Speed Performance: The phenolic cage material offers excellent strength-to-weight ratio, contributing to the bearing's limiting speed of 17,000 rpm. This makes it suitable for high-speed spindle applications requiring minimal centrifugal forces.
Universal Matching Capability: Designed as Universal Matchable (SU), these bearings can be arranged in back-to-back, face-to-face, or tandem configurations without selective matching, simplifying installation and maintenance.
