Super Precision Angular Contact Ball Bearings S71912 ACB/HCP4ADT

Super Precision Angular Contact Ball Bearings S71912 ACB/HCP4ADT

The S71912 ACB/HCP4ADT is a super precision angular contact ball bearing with a 60mm bore and 85mm outer diameter, crafted from durable chrome steel. Its 25° contact angle and ceramic balls ensure smooth operation under radial loads up to 3578 lbf.

Sealed for protection and preloaded for stability, this bearing set (two matched units) handles high speeds up to 36,000 RPM. The phenolic cage reduces friction, while grease lubrication simplifies maintenance.

Ideal for precision applications like machine tool spindles or high-speed robotics, it performs reliably between -30°C and 110°C. With a P4A tolerance class, it meets strict accuracy standards for demanding environments.

Weighing 0.38kg, this SKF-interchangeable model balances lightweight design with robust performance. Its matched arrangement ensures consistent load distribution in paired setups.
