Super Precision Angular Contact Ball Bearings 71944 CDGC/P4A

Super Precision Angular Contact Ball Bearings 71944 CDGC/P4A

The 71944 CDGC/P4A is a super precision angular contact ball bearing with a 220mm bore and 300mm outer diameter, crafted from high-grade chrome steel. It supports both dynamic and static radial loads up to 49725 lbf and 67500 lbf respectively, with a maximum speed of 7500 RPM.

Its 15° contact angle and moderate preload (Class C) ensure smooth operation under angular loads. The open design and phenolic cage make it durable and easy to maintain, even in temperatures ranging from -30°C to 110°C.

This bearing is part of a universal matching set of four, suitable for back-to-back, face-to-face, or tandem arrangements. Ideal for high-precision applications like machine tool spindles or aerospace components where accuracy is crucial.

Weighing 6.6kg, it’s robust yet manageable for its size. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for reliable replacements.
