S7014 ACDGB/P4A Bearing Product Overview & Core Advantages
The S7014 ACDGB/P4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. As a single bearing with Universal Matchable (SU) designation, it can be paired with other identical bearings in sets to achieve optimal preload and stiffness. Its P4A tolerance class ensures ultra-precise dimensional control, making it ideal for high-speed spindles and precision machinery. The bearing is capable of supporting combined loads (radial and axial) simultaneously, with a 25° contact angle providing excellent axial load capacity. Pre-lubricated with grease and featuring a sealed design, it offers long-term, maintenance-free operation.

S7014 ACDGB/P4A Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, ensuring exceptional running accuracy and minimal vibration.
Optimized Load Capacity: The 25° contact angle provides superior axial load capacity while maintaining good radial load performance (Radial dynamic load rating: 10980 lbf).
High-Speed Capability: Featuring a phenolic cage and precision-ground chrome steel components, the bearing achieves a limiting speed of 22,000 rpm, making it suitable for high-speed applications.
Universal Matching Design: As a Universal Matchable (SU) bearing, it can be mounted in back-to-back (DB), face-to-face (DF), or tandem (DT) arrangements without performance degradation.
Maintenance-Free Operation: Factory-sealed and pre-lubricated with grease, providing protection against contamination and ensuring long service life without relubrication.
