Super Precision Angular Contact Ball Bearings 71908 ACEGA/HCP4AL

Super Precision Angular Contact Ball Bearings 71908 ACEGA/HCP4AL

The 71908 ACEGA/HCP4AL is a super precision angular contact ball bearing with a 40mm bore and 62mm outer diameter, crafted from chrome steel for durability. Its 25° contact angle and ceramic balls ensure smooth operation at high speeds, up to 41,000 RPM.

This open-design bearing handles radial loads up to 2106 lbf and comes pre-lubricated for immediate use. The phenolic cage adds strength while keeping weight low at just 0.088kg.

With a P4A tolerance class, it offers excellent precision for demanding applications. Ideal for high-speed spindles or precision machinery where accuracy is key.

The bearing can be paired in back-to-back, face-to-face, or tandem arrangements for versatile use. It operates reliably in temperatures from -30°C to 110°C.
