Super Precision Angular Contact Ball Bearings S71908 CB/HCP4ADBC

Super Precision Angular Contact Ball Bearings S71908 CB/HCP4ADBC

The S71908 CB/HCP4ADBC is a super precision angular contact ball bearing with a 40mm bore and 62mm outer diameter, designed for high-speed applications. Its compact 24mm width and matched pair setup (DB arrangement) provide stability under moderate preload.

Made from chrome steel with ceramic balls and a phenolic cage, it handles radial loads up to 1960 lbf and spins smoothly at 41,000 RPM. The sealed design keeps grease in and contaminants out, reducing maintenance needs.

With a 15° contact angle and P4A tolerance class, it offers precise performance for demanding tasks. Ideal for machine tool spindles or high-speed robotics where accuracy and speed matter.

Weighing 0.24kg, it operates in temperatures from -30°C to 110°C. This model is interchangeable with SKF bearings, making replacements straightforward.
