Super Precision Angular Contact Ball Bearings 7011 ACD/P4ADGB

Super Precision Angular Contact Ball Bearings 7011 ACD/P4ADGB

The 7011 ACD/P4ADGB is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from high-quality chrome steel. It features a 25° contact angle and comes in a universal matching set of two bearings.

This model handles radial loads up to 13612 lbf and reaches speeds of 34000 RPM, thanks to its phenolic cage and lubricated design. Its P4A tolerance class ensures exceptional accuracy for demanding applications.

The open seal allows for easy maintenance, while the universal matching enables flexible arrangements (back-to-back, face-to-face, or tandem). Ideal for high-speed spindles or precision machinery where tight tolerances are crucial.

Weighing 0.76kg, it operates smoothly in temperatures from -30°C to 110°C. Compatible with SKF bearings, it’s a reliable choice for replacements or upgrades in precision engineering setups.
