Super Precision Angular Contact Ball Bearings 7011 ACD/P4ATBTC

Super Precision Angular Contact Ball Bearings 7011 ACD/P4ATBTC

The 7011 ACD/P4ATBTC 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 18135 lbf and operates smoothly at speeds up to 34000 RPM.

Its 25° contact angle and matched set of three bearings (arranged TBT) provide stability for angular loads, while the phenolic cage ensures quiet performance. The moderate preload (Class C) offers balanced stiffness and smooth rotation.

This open-design bearing comes pre-lubricated and works in temperatures from -30°C to 110°C. Ideal for high-precision applications like machine tool spindles or high-speed robotics.

Weighing 1.13kg, it meets P4A tolerance standards for exceptional accuracy. Interchangeable with SKF bearings, making it a practical choice for replacements or upgrades.
