Super Precision Angular Contact Ball Bearings 71906 CE/HCPA9ADT

Super Precision Angular Contact Ball Bearings 71906 CE/HCPA9ADT

The 71906 CE/HCPA9ADT is a super precision angular contact ball bearing, measuring 30mm by 47mm by 18mm, crafted from chrome steel with ceramic balls for enhanced performance. It handles radial loads up to 2077 lbf and spins smoothly at speeds up to 100,500 RPM.

Its 15° contact angle and matched pair design (2 bearings << DT) provide excellent stability under angular loads, while the phenolic cage ensures quiet operation. The open seal allows for easy lubrication and maintenance. Ideal for high-speed applications like machine tool spindles or precision instruments, where accuracy and low friction are key. It operates reliably in temperatures from -30°C to 110°C. Weighing just 0.09kg, this bearing is lightweight yet robust, meeting PA9A tolerance standards for precision engineering. Interchangeable with SKF bearings for convenient replacements.
