7011 FEGA/P4A Bearing Product Overview & Core Advantages
The 7011 FEGA/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing delivers superior running accuracy and is universally matchable (SU), allowing for precise preload control when mounted in pairs. Its optimized 18° contact angle provides excellent performance under combined radial and axial loads. The bearing comes pre-lubricated and features an open design for high-speed operation up to 34,000 rpm, making it ideal for demanding machine tool and precision engineering applications.

7011 FEGA/P4A Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4A tolerance standards with tight dimensional control (bore and OD tolerance: -0.004mm to 0) ensuring exceptional running accuracy and minimal vibration.
Optimized Load Capacity: The 18° contact angle configuration enables efficient handling of combined radial and axial loads, with dynamic load rating of 3712 lbf and static load rating of 2700 lbf.
High-Speed Performance: The phenolic resin cage provides excellent strength-to-weight ratio and lubrication retention, supporting limiting speeds of 34,000 rpm while maintaining stability.
Universal Matching Capability: Designed as Universal Matchable (SU), these bearings can be paired in any combination to achieve precise preload settings without selective matching.
Premium Material Selection: Constructed from chrome steel for both rings and balls, ensuring high hardness, wear resistance, and long service life in demanding applications.
