Super Precision Angular Contact Ball Bearings 71901 CE/HCPA9ADT

Super Precision Angular Contact Ball Bearings 71901 CE/HCPA9ADT

The 71901 CE/HCPA9ADT is a super precision angular contact ball bearing, measuring 12mm by 24mm by 12mm. Made from chrome steel with ceramic balls, it offers smooth operation and durability. Its 15° contact angle and paired arrangement (DT) provide stability under angular loads.

This bearing handles dynamic radial loads up to 776 lbf and spins at speeds up to 165,000 RPM. The phenolic cage ensures quiet performance, while the open design allows for easy lubrication. It operates in temperatures from -30°C to 110°C.

With a PA9A tolerance class, it’s ideal for high-precision applications like machine tools or spindle drives. The matched set of two bearings ensures balanced performance. Weighing just 0.018kg, it’s lightweight yet robust for its size. Interchangeable with SKF bearings for easy replacement.
