Super Precision Angular Contact Ball Bearings 71920 CE/HCP4AQBCA

Super Precision Angular Contact Ball Bearings 71920 CE/HCP4AQBCA

The 71920 CE/HCP4AQBCA is a super precision angular contact ball bearing with a 100mm bore and 140mm outer diameter, crafted from chrome steel for durability. It features a 15° contact angle and comes in a matched set of four bearings for balanced performance.

This bearing handles radial loads up to 23400 lbf and spins smoothly at speeds up to 16000 RPM, thanks to its ceramic balls and phenolic cage. The extra-light preload ensures minimal friction during operation.

Its open design allows for easy lubrication, while the P4A tolerance class guarantees high precision. Ideal for applications like machine tool spindles or high-speed robotics where accuracy is key.

Weighing 2.6kg, it’s robust yet manageable for its size. The temperature range of -30°C to 110°C makes it suitable for various industrial environments. Interchangeable with SKF bearings for convenient replacements.
