Super Precision Angular Contact Ball Bearings 71910 CE/P4ADBA

Super Precision Angular Contact Ball Bearings 71910 CE/P4ADBA

The 71910 CE/P4ADBA is a super precision angular contact ball bearing, measuring 50mm by 72mm by 24mm. Made from chrome steel, it features a 15° contact angle and comes in a matched pair for extra stability.

This bearing handles radial loads up to 4680 lbf and spins smoothly at speeds up to 46,000 RPM. Its open design allows easy lubrication, while the phenolic cage ensures quiet operation.

The extra light preload (Class A) reduces friction, making it ideal for high-precision applications. It works well in temperatures from -30°C to 110°C.

Perfect for machine tools or spindle systems where accuracy and speed are key. Weighing just 0.26kg, it’s lightweight yet durable. Interchangeable with SKF bearings for easy replacement.
