Super Precision Angular Contact Ball Bearings S71926 CD/P4ADGA

Super Precision Angular Contact Ball Bearings S71926 CD/P4ADGA

The S71926 CD/P4ADGA is a super precision angular contact ball bearing with a 130mm bore and 180mm outer diameter, crafted from durable chrome steel. Its compact 48mm width and sealed design make it suitable for high-precision applications.

With a 15° contact angle, it handles radial loads up to 33,300 lbf and spins smoothly at 11,000 RPM. The phenolic cage and grease lubrication ensure quiet operation and long service life.

This bearing comes in a matched set of two, allowing universal mounting (back-to-back, face-to-face, or tandem). Ideal for machine tools or spindles where precision and reliability are key.

Weighing 3.16kg, it operates in temperatures from -30°C to 110°C, meeting P4A tolerance standards for exceptional accuracy.
