Super Precision Angular Contact Ball Bearings S71920 CDGD/P4A

Super Precision Angular Contact Ball Bearings S71920 CDGD/P4A

The S71920 CDGD/P4A is a super precision angular contact ball bearing with a 100mm bore and 140mm outer diameter, crafted from durable chrome steel. It handles heavy radial loads up to 13612 lbf and operates smoothly at speeds up to 16250 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The bearing works reliably in temperatures from -30°C to 110°C.

With a 15° contact angle and heavy preload, it’s ideal for high-precision applications like machine tool spindles or robotics. The bearing can be paired in back-to-back, face-to-face, or tandem arrangements for added versatility.

Weighing 0.81kg, it’s a robust choice for demanding environments. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacement.
