Super Precision Angular Contact Ball Bearings S71910 ACEGB/HCP4A

Super Precision Angular Contact Ball Bearings S71910 ACEGB/HCP4A

The S71910 ACEGB/HCP4A is a super precision angular contact ball bearing with a 50mm bore and 72mm outer diameter, crafted from chrome steel for durability. Its 25° contact angle and ceramic balls ensure smooth operation under radial loads up to 2722 lbf.

The sealed design keeps grease in and contaminants out, while the phenolic cage offers lightweight stability. It spins at speeds up to 34,000 RPM, making it suitable for high-performance applications.

This bearing comes in a matched set of two, allowing flexible arrangements like back-to-back or face-to-face mounting. Ideal for precision machinery, spindles, or tools requiring tight tolerances and low friction.

Weighing just 0.11kg, it’s lightweight yet robust, with a temperature range of -30°C to 110°C. Compliant with P4A tolerance class for exceptional accuracy.
