Super Precision Angular Contact Ball Bearings 71915 CEGA/HCP4A

Super Precision Angular Contact Ball Bearings 71915 CEGA/HCP4A

The 71915 CEGA/HCP4A is a super precision angular contact ball bearing with a 75mm bore and 105mm outer diameter, crafted from chrome steel for durability. It features a 15° contact angle and ceramic balls for smooth operation.

This bearing handles radial loads up to 5062 lbf and spins at speeds up to 36,000 RPM, making it suitable for high-performance applications. Its phenolic cage ensures stability and reduces friction.

Designed for angular contact loads, it comes with an extra light preload (Class A) for precise movement. The open seal allows easy lubrication, and it works in temperatures from -30°C to 110°C.

Ideal for machine tools or high-speed spindles, this bearing is interchangeable with SKF models. Weighing 0.29kg, it’s lightweight yet robust. It can be paired in back-to-back, face-to-face, or tandem arrangements for versatile use.
