Super Precision Angular Contact Ball Bearings 7011 ACD/P4ATBTD

Super Precision Angular Contact Ball Bearings 7011 ACD/P4ATBTD

The 7011 ACD/P4ATBTD is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from high-quality chrome steel. It handles heavy 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 excellent stability under heavy preload conditions. The phenolic cage ensures durability and reduces friction.

This bearing is ideal for high-precision applications like machine tool spindles or high-speed robotics. It works reliably in temperatures from -30°C to 110°C and comes pre-lubricated for immediate use.

Weighing 1.13kg, it’s a robust choice for demanding environments. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacement.
