Super Precision Angular Contact Ball Bearings S7008 ACD/P4AQBTC

Super Precision Angular Contact Ball Bearings S7008 ACD/P4AQBTC

The S7008 ACD/P4AQBTC is a super precision angular contact ball bearing with a 40mm bore and 68mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 9518 lbf and spins smoothly at speeds up to 41,000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet operation. The 25° contact angle and moderate preload make it ideal for high-precision applications.

This bearing comes in a matched set of four, optimised for stability under angular loads. Perfect for machine tools or spindle drives where accuracy and speed are key.

Weighing 0.77kg, it operates reliably in temperatures from -30°C to 110°C. Compliant with P4A tolerance standards for consistent performance.
