Super Precision Angular Contact Ball Bearings 71900 ACE/HCP4ADGA

Super Precision Angular Contact Ball Bearings 71900 ACE/HCP4ADGA

The 71900 ACE/HCP4ADGA is a super precision angular contact ball bearing with a compact 10mm bore and 22mm outer diameter, crafted from high-quality chrome steel. Its 25° contact angle and ceramic balls ensure smooth operation under angular loads.

This bearing handles dynamic radial loads up to 702 lbf and spins remarkably fast, reaching speeds of 165,000 RPM. The phenolic cage and lubricated design contribute to its quiet performance and long service life.

With universal matching capability, it can be arranged back-to-back, face-to-face, or tandem. The extra light preload (Class A) makes it ideal for precision applications requiring minimal friction.

Perfect for high-speed spindles or precision instruments, this P4A-class bearing operates in temperatures from -30°C to 110°C. The matched set of two bearings weighs just 0.016kg, offering excellent performance in a lightweight package.
