Super Precision Angular Contact Ball Bearings 71920 FE/HCP4ALDT

Super Precision Angular Contact Ball Bearings 71920 FE/HCP4ALDT

The 71920 FE/HCP4ALDT is a super precision angular contact ball bearing with a 100mm bore and 140mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 14040 lbf and spins smoothly at speeds up to 16000 RPM.

Its 18° contact angle and matched arrangement (2 bearings << DT) provide excellent stability, while the phenolic cage ensures quiet operation. The open design allows for easy lubrication and maintenance. This bearing is ideal for high-precision applications like machine tool spindles or high-speed robotics, operating in temperatures from -30°C to 110°C. Compliant with P4A tolerance class for exceptional accuracy. Weighing 1.3kg, it's a robust yet lightweight solution for demanding environments. Interchangeable with SKF bearings for convenient replacements.
