Super Precision Angular Contact Ball Bearings S71913 ACB/HCP4A

Super Precision Angular Contact Ball Bearings S71913 ACB/HCP4A

The S71913 ACB/HCP4A is a super precision angular contact ball bearing with a 65mm bore and 90mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 2239 lbf and spins smoothly at speeds up to 22,000 RPM.

Its sealed design keeps lubrication in place, while the phenolic cage reduces friction for long-lasting performance. The 25° contact angle and P4 tolerance class ensure high accuracy in demanding applications.

This bearing is ideal for precision machinery like CNC spindles or high-speed robotics, where tight tolerances and reliability are key. It’s also available in matched sets for paired mounting.

Weighing just 0.2kg, it’s lightweight yet robust, and operates reliably in temperatures from -30°C to 110°C. Interchangeable with SKF bearings, it’s a versatile choice for replacements or upgrades.
