Super Precision Angular Contact Ball Bearings 71901 CE/HCP4ADGA

Super Precision Angular Contact Ball Bearings 71901 CE/HCP4ADGA

The 71901 CE/HCP4ADGA is a super precision angular contact ball bearing with a compact 12mm bore and 24mm outer diameter, crafted from chrome steel for durability. Its 15° contact angle and ceramic balls ensure smooth operation under radial loads up to 776 lbf.

With a phenolic cage and open design, it supports speeds up to 220,000 RPM while maintaining stability. The extra light preload (Class A) reduces friction, making it ideal for high-speed applications.

This bearing comes in a matched set of two, allowing universal mounting in back-to-back, face-to-face, or tandem configurations. Perfect for precision tools, spindles, or small machinery where accuracy and speed matter.

Weighing just 0.018kg, it’s lightweight yet robust, operating reliably between -30°C and 110°C. Compliant with P4A tolerance standards for consistent performance.
