Super Precision Angular Contact Ball Bearings S71908 CB/HCP4ADGA

Super Precision Angular Contact Ball Bearings S71908 CB/HCP4ADGA

The S71908 CB/HCP4ADGA is a super precision angular contact ball bearing, measuring 40mm by 62mm by 24mm. Made from chrome steel with ceramic balls, it offers smooth operation and durability. Its sealed design keeps grease in and contaminants out.

With a 15° contact angle, it handles both radial and axial loads efficiently. It can spin up to 41,000 RPM and works in temperatures from -30°C to 110°C. The phenolic cage ensures stability at high speeds.

This bearing comes in a matched set of two, allowing universal mounting options (back-to-back, face-to-face, or tandem). Ideal for high-precision applications like machine tools or spindle drives.

Weighing just 0.24kg, it’s lightweight yet robust. Compliant with P4A tolerance class for exceptional accuracy. Interchangeable with SKF bearings for easy replacement.
