7011 ACE/HCP4ALDGA Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The combination of chrome steel rings and ceramic balls provides superior high-speed performance, reduced friction, and extended service life. Ceramic balls offer excellent dimensional stability and thermal resistance.
Phenolic Resin Cage: The lightweight phenolic cage ensures smooth operation at limiting speeds up to 34,000 rpm, providing excellent strength-to-weight ratio and reduced centrifugal forces.
Universal Matchable Design: As a Universal Matchable (SU) bearing, it can be paired with identical bearings in various configurations to handle combined radial and axial loads efficiently.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control (bore and OD tolerance: -0.004mm to 0), ensuring exceptional running accuracy and minimal vibration.
Optimized Load Capacity: With a 25° contact angle and 24 ceramic balls, this bearing delivers excellent radial dynamic load rating of 5,850 lbf and static load rating of 5,220 lbf.
