Super Precision Angular Contact Ball Bearings 71900 CD/P4ADT

Super Precision Angular Contact Ball Bearings 71900 CD/P4ADT

The 71900 CD/P4ADT is a super precision angular contact ball bearing with a compact 10mm bore and 22mm outer diameter. Its 15° contact angle and matched pair design (2 bearings << DT) provide stable performance under angular loads. Made from chrome steel with a phenolic cage, it handles radial loads up to 922 lbf and spins smoothly at speeds up to 165,000 RPM. The open design allows easy lubrication, while the P4A tolerance ensures high precision. This bearing excels in applications requiring tight control, such as machine tool spindles or precision instruments. Its lightweight design (0.018kg per bearing) makes it suitable for compact spaces. Operating between -30°C to 110°C, it's interchangeable with SKF bearings for easy replacement. The preload option adds versatility for different setup requirements.
