Super Precision Angular Contact Ball Bearings 71816 CDGC/P4

Super Precision Angular Contact Ball Bearings 71816 CDGC/P4

The 71816 CDGC/P4 is a super precision angular contact ball bearing with an 80mm bore and 100mm outer diameter, crafted from durable chrome steel. Its compact 10mm width makes it suitable for tight spaces while handling moderate preloads.

With a 15° contact angle, it manages radial loads up to 3285 lbf and spins smoothly at 28,000 RPM. The phenolic cage ensures quiet operation and long service life, even in temperatures from -30°C to 110°C.

This bearing comes lubricated for immediate use and meets P4 tolerance standards for high-precision applications. It’s universally matchable in back-to-back, face-to-face, or tandem arrangements.

Ideal for precision machinery like spindles or CNC equipment where accuracy and speed matter. Weighing just 0.15kg, it offers excellent performance without adding bulk. Interchangeable with SKF bearings for easy replacement.
