Super Precision Angular Contact Ball Bearings 71914 CEGA/HCP4AL

Super Precision Angular Contact Ball Bearings 71914 CEGA/HCP4AL

The 71914 CEGA/HCP4AL is a super precision angular contact ball bearing with a 70mm bore and 100mm outer diameter, crafted from high-quality chrome steel. Its compact 16mm width makes it suitable for tight spaces while maintaining robust performance.

With a 15° contact angle, it handles both radial and thrust loads efficiently, supporting up to 4972 lbf dynamically. The ceramic balls and phenolic cage allow it to spin smoothly at speeds up to 28,000 RPM.

Its open design and extra-light preload ensure minimal friction and easy lubrication. The bearing operates reliably in temperatures from -30°C to 110°C.

Ideal for high-precision applications like machine tool spindles or aerospace components. Weighing just 0.27kg, it’s lightweight yet durable. Compliant with P4A tolerance class for exceptional accuracy.

This bearing can be matched in sets of three for back-to-back, face-to-face, or tandem arrangements, offering flexibility in complex setups. Interchangeable with SKF models for easy replacement.
