Super Precision Angular Contact Ball Bearings S7011 ACEGB/P4A

Super Precision Angular Contact Ball Bearings S7011 ACEGB/P4A

The S7011 ACEGB/P4A 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 sealed for protection, with a phenolic cage for durability.

This bearing handles dynamic radial loads up to 3578 lbf and spins smoothly at speeds up to 34,000 RPM. Its light preload (Class B) ensures quiet operation and reduced friction.

The sealed design keeps grease in and contaminants out, making it low-maintenance. It operates reliably in temperatures from -30°C to 110°C.

Ideal for high-precision applications like machine tool spindles or robotics, where accuracy and speed are key. Weighing 0.4kg, it’s part of a universal matching set for flexible configurations.
