Super Precision Angular Contact Ball Bearings 71810 CD/P4DBA

Super Precision Angular Contact Ball Bearings 71810 CD/P4DBA

The 71810 CD/P4DBA is a super precision angular contact ball bearing with a 50mm bore and 65mm outer diameter, crafted from high-quality chrome steel. It features a 15° contact angle and comes in a matched set of two bearings for balanced performance.

This model handles radial loads up to 2722 lbf and can spin at speeds up to 46,000 RPM, making it suitable for high-speed applications. The phenolic cage ensures smooth operation and durability under stress.

Its open design allows for easy lubrication, while the extra-light preload (Class A) ensures minimal friction. The bearing operates efficiently in temperatures ranging from -30°C to 110°C.

Ideal for precision machinery like CNC spindles or high-speed motors, where accuracy and reliability are key. Weighing just 0.1kg, it’s lightweight yet robust for its size. Interchangeable with SKF bearings for easy replacement.
