Super Precision Angular Contact Ball Bearings 71805 ACDGC/P4

Super Precision Angular Contact Ball Bearings 71805 ACDGC/P4

The 71805 ACDGC/P4 is a super precision angular contact ball bearing with a 25mm bore and 37mm outer diameter, designed for high-speed applications. Its 25° contact angle efficiently handles combined radial and axial loads up to 878 lbf.

The chrome steel construction ensures durability, while the phenolic cage reduces friction for smoother rotation at speeds up to 103,000 RPM. The open design allows easy lubrication and maintenance.

With a P4 tolerance class, this bearing offers excellent precision for demanding machinery. It’s suitable for spindle drives or high-performance tools where accuracy and speed are crucial.

Weighing just 0.021kg, it’s lightweight yet robust. The bearing can be matched in sets of three for back-to-back, face-to-face, or tandem arrangements, providing flexibility in various installations.
