Super Precision Angular Contact Ball Bearings 71913 CEGA/HCP4A

Super Precision Angular Contact Ball Bearings 71913 CEGA/HCP4A

The 71913 CEGA/HCP4A is a super precision angular contact ball bearing with a 65mm bore and 90mm outer diameter, made from high-quality chrome steel. It features ceramic balls and a phenolic cage for smooth operation at high speeds.

With a 15° contact angle, it handles both radial and thrust loads efficiently, supporting up to 3712 lbf dynamically. Its extra-light preload ensures minimal friction, making it ideal for high-speed applications up to 32,500 RPM.

The open design allows easy lubrication, while the P4A tolerance class guarantees precise performance. Suitable for temperatures from -30°C to 110°C, it works well in demanding environments.

This bearing is interchangeable with SKF models and can be paired in back-to-back, face-to-face, or tandem arrangements. Perfect for machine tools or precision equipment where accuracy and speed are crucial. Weighing just 0.17kg, it’s lightweight yet durable.
