Super Precision Angular Contact Ball Bearings 71813 ACD/P4DGB

Super Precision Angular Contact Ball Bearings 71813 ACD/P4DGB

The 71813 ACD/P4DGB is a super precision angular contact ball bearing with a 65mm bore and 85mm outer diameter, crafted from high-quality chrome steel. Its 25° contact angle and open design ensure smooth operation under radial loads up to 4680 lbf.

This bearing spins efficiently at speeds up to 36,000 RPM and works in temperatures from -30°C to 110°C. The phenolic cage reduces friction, while the universal matching design allows flexible arrangements like back-to-back or face-to-face.

With a lightweight build at just 0.25kg, it’s ideal for high-precision applications like machine tool spindles or robotics. Compliant with P4 tolerance standards, it’s a reliable choice for demanding environments.
