Super Precision Angular Contact Ball Bearings 7011 ACD/P4ADBA

Super Precision Angular Contact Ball Bearings 7011 ACD/P4ADBA

The 7011 ACD/P4ADBA is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from high-quality chrome steel. It handles radial loads up to 13612 lbf and operates smoothly at speeds up to 34000 RPM.

Its 25° contact angle and matched arrangement of two bearings (DB) provide excellent stability for angular loads. The phenolic cage ensures durability and quiet operation, even at high speeds.

Designed for extra light preload (Class A), this bearing is ideal for precision applications like machine tool spindles or high-speed robotics. It works reliably in temperatures from -30°C to 110°C.

Weighing 0.76kg, it’s a robust yet manageable size for its performance. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacements.
