Super Precision Angular Contact Ball Bearings S71908 ACB/HCP4ADT

Super Precision Angular Contact Ball Bearings S71908 ACB/HCP4ADT

The S71908 ACB/HCP4ADT is a super precision angular contact ball bearing with a 40mm bore and 62mm outer diameter, measuring 24mm wide. Made from chrome steel and ceramic balls, it offers high durability and smooth operation.

This bearing handles radial loads up to 1843 lbf and spins at speeds up to 41,000 RPM, thanks to its phenolic cage and grease lubrication. Its 25° contact angle and matched arrangement (2 bearings << DT) ensure stable performance under angular loads. The sealed design keeps contaminants out, while the P4A tolerance class guarantees precision. Ideal for high-speed applications like machine tool spindles or precision instruments. Weighing just 0.24kg, it’s lightweight yet robust, and operates in temperatures from -30°C to 110°C. A reliable choice for engineers needing accuracy and speed.
