Super Precision Angular Contact Ball Bearings 71914 CEGA/HCP4A

Super Precision Angular Contact Ball Bearings 71914 CEGA/HCP4A

The 71914 CEGA/HCP4A is a super precision angular contact ball bearing with a 70mm bore and 100mm outer diameter, crafted from durable chrome steel. Its 15° contact angle and ceramic balls ensure smooth operation under radial loads up to 4972 lbf.

This bearing spins at speeds up to 28,000 RPM, thanks to its phenolic cage and extra-light preload design. It performs reliably in temperatures ranging from -30°C to 110°C.

Its open seal allows for easy lubrication, while the P4A tolerance class guarantees high precision. The bearing can be used in matched sets for back-to-back, face-to-face, or tandem arrangements.

Weighing just 0.27kg, it’s ideal for high-speed applications like machine tool spindles or precision instruments. Interchangeable with SKF bearings, it offers a practical replacement option.
