Super Precision Angular Contact Ball Bearings 71906 CE/HCPA9ADGA

Super Precision Angular Contact Ball Bearings 71906 CE/HCPA9ADGA

The 71906 is a super precision angular contact ball bearing measuring 30mm by 47mm by 18mm, crafted from chrome steel with ceramic balls for smooth operation. It handles radial loads up to 2077 lbf and spins at speeds over 100,000 RPM, making it ideal for high-performance applications.

Its 15° contact angle and phenolic cage ensure stability under angular loads, while the extra-light preload reduces friction. The open design allows easy lubrication, extending its lifespan in demanding conditions.

This bearing comes in a matched set of two, suitable for universal arrangements like back-to-back or face-to-face mounting. Perfect for precision machinery, spindles, or high-speed tools where accuracy is key.

Weighing just 0.09kg, it’s lightweight yet robust, operating smoothly from -30°C to 110°C. Compatible with SKF models for easy replacement.
