Super Precision Angular Contact Ball Bearings 71913 CE/HCPA9ADGA

Super Precision Angular Contact Ball Bearings 71913 CE/HCPA9ADGA

The 71913 CE/HCPA9ADGA is a super precision angular contact ball bearing with a 65mm bore and 90mm outer diameter, crafted from durable chrome steel. It features a 15° contact angle and ceramic balls for smooth operation.

This bearing handles radial loads up to 6075 lbf and spins at speeds up to 31,000 RPM. Its phenolic cage and universal matching design ensure reliable performance in high-speed applications.

The open seal type allows for easy lubrication, while the extra light preload (Class A) minimises friction. It operates efficiently in temperatures from -30°C to 110°C.

Ideal for precision machinery like spindles or CNC tools, this bearing comes in a matched set of two for versatile mounting options (back-to-back, face-to-face, or tandem). Weighing just 0.34kg, it balances lightweight design with robust performance.
