Super Precision Angular Contact Ball Bearings 7011 CD/P4ADBC

Super Precision Angular Contact Ball Bearings 7011 CD/P4ADBC

The 7011 CD/P4ADBC is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 14332 lbf and reaches speeds of 34000 RPM, making it suitable for high-performance applications.

Its 15° contact angle and matched arrangement (2 bearings DB) provide stability under combined loads. The phenolic cage ensures smooth operation and reduces friction, even at high speeds.

This bearing is lubricated for long service life and operates in temperatures from -30°C to 110°C. Its P4A tolerance class guarantees precision, ideal for machine tools or spindle systems.

Weighing 0.76kg, it’s robust yet manageable for its size. Interchangeable with SKF bearings, it’s a reliable choice for replacements or upgrades in demanding settings.
