7011 ACEGA/P4AH1 Bearing Product Overview & Core Advantages
The 7011 ACEGA/P4AH1 is a single-row angular contact ball bearing designed for applications requiring high precision and superior performance under combined loads. Manufactured to P4A tolerance class, this bearing delivers exceptional dimensional accuracy and running precision. Its 25° contact angle provides optimal capacity for handling both radial and axial loads simultaneously. The bearing comes pre-lubricated and features an open seal type with phenolic cage construction, making it suitable for high-speed operation up to 34,000 rpm while maintaining dimensional stability across a wide temperature range (-30°C to 110°C).

Structural Features & Performance Advantages
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring exceptional running accuracy and minimal vibration.
High-Speed Capability: The phenolic cage and optimized internal geometry enable stable operation at limiting speeds of 34,000 rpm, while the 25° contact angle provides balanced load distribution.
Superior Load Capacity: With radial dynamic load rating of 3,578 lbf and static load rating of 2,610 lbf, this bearing handles significant combined loads efficiently through its precision-ground raceways and 24 chrome steel balls.
Thermal Stability: The phenolic cage material and chrome steel construction maintain dimensional integrity across the operating temperature range of -30°C to 110°C.
Universal Matching: Designated as Universal Matchable (SU), these bearings can be directly paired in duplex sets without selective matching, simplifying installation and maintenance.
