Super Precision Angular Contact Ball Bearings 71804 ACD/P4DFBVT162

Super Precision Angular Contact Ball Bearings 71804 ACD/P4DFBVT162

The 71804 ACD/P4DFBVT162 is a super precision angular contact ball bearing with a 20mm bore and 32mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 1332 lbf and spins smoothly at speeds up to 121,000 RPM.

With a 25° contact angle and light preload, it offers excellent stability for high-speed applications. The phenolic cage ensures quiet operation and long service life.

This matched set of two bearings (DF arrangement) is ideal for precision machinery like spindles or CNC tools. It operates reliably in temperatures from -30°C to 110°C.

Weighing just 0.036kg, it’s lightweight yet robust. The open design allows easy greasing, and it’s interchangeable with SKF bearings for convenient replacements.
