Super Precision Angular Contact Ball Bearings 71806 ACDGB/P4

Super Precision Angular Contact Ball Bearings 71806 ACDGB/P4

The 71806 ACDGB/P4 is a super precision angular contact ball bearing with a 30mm bore and 42mm outer diameter, measuring just 7mm wide. Made from chrome steel, it’s designed for high-speed applications, handling radial loads up to 936 lbf.

With a 25° contact angle and light preload, it offers smooth rotation at speeds up to 100,500 RPM. The phenolic cage ensures durability while keeping the bearing lightweight at only 0.026kg.

Its open design allows easy lubrication, and it operates reliably in temperatures from -30°C to 110°C. This bearing is interchangeable with SKF models, making it a versatile choice for replacements.

Ideal for precision machinery like spindles or CNC tools, it can be paired in back-to-back, face-to-face, or tandem arrangements for added flexibility. The P4 tolerance class ensures consistent performance in demanding applications.
