Super Precision Angular Contact Ball Bearings S71909 CD/P4A

Super Precision Angular Contact Ball Bearings S71909 CD/P4A

The S71909 CD/P4A is a super precision angular contact ball bearing with a 45mm bore and 68mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 2925 lbf and spins smoothly at speeds up to 19,000 RPM.

Its sealed design keeps lubrication in and contaminants out, while the phenolic cage reduces friction for quieter operation. The 15° contact angle makes it ideal for combined radial and axial loads.

This bearing comes preloaded and matched for precision applications, meeting P4 (ABEC-7) tolerance standards. Perfect for high-speed machinery like spindles or CNC equipment where accuracy is key.

Weighing just 0.13kg, it’s lightweight yet robust. It operates reliably in temperatures from -30°C to 110°C and is interchangeable with SKF bearings for easy replacement.
