Super Precision Angular Contact Ball Bearings 71908 FEGA/HCP4A

Super Precision Angular Contact Ball Bearings 71908 FEGA/HCP4A

The 71908 FEGA/HCP4A is a super precision angular contact ball bearing with a 40mm bore and 62mm outer diameter, crafted from chrome steel for durability. It features ceramic balls and a phenolic cage, ensuring smooth operation at high speeds up to 41,000 RPM.

With an 18° contact angle, it handles both dynamic and static radial loads efficiently, up to 2194 lbf and 1350 lbf respectively. Its extra-light preload (Class A) enhances precision in demanding applications.

The open design allows for easy lubrication, while the P4A tolerance class guarantees exceptional accuracy. Ideal for high-speed spindles or precision machinery where minimal friction is crucial.

Weighing just 0.088kg, it’s lightweight yet robust. Compatible with SKF bearings and suitable for universal matching in back-to-back, face-to-face, or tandem arrangements. Works reliably in temperatures from -30°C to 110°C.
