Super Precision Angular Contact Ball Bearings S71908 CE/HCP4ADBA

Super Precision Angular Contact Ball Bearings S71908 CE/HCP4ADBA

The S71908 CE/HCP4ADBA is a super precision angular contact ball bearing, measuring 40mm by 62mm by 24mm, crafted from chrome steel for durability. It features a 15° contact angle and comes sealed for protection, with two bearings arranged back-to-back for stability.

Designed for angular contact loads, it handles dynamic radial loads up to 3578 lbf and spins smoothly at speeds up to 41,000 RPM. The ceramic balls and phenolic cage reduce friction, enhancing performance.

Its extra-light preload ensures quiet operation, ideal for high-precision applications like machine tools or spindles. The grease lubrication simplifies maintenance, while the P4A tolerance class guarantees accuracy.

Weighing just 0.19kg, this bearing is lightweight yet robust, suitable for temperatures from -30°C to 110°C. It’s interchangeable with SKF bearings, making replacements straightforward.
