Super Precision Angular Contact Ball Bearings S71910 CD/HCP4ADBC

Super Precision Angular Contact Ball Bearings S71910 CD/HCP4ADBC

The S71910 CD/HCP4ADBC is a super precision angular contact ball bearing with a 50mm bore and 72mm outer diameter, measuring 24mm in width. Made from chrome steel and ceramic balls, it offers smooth operation and durability.

This bearing handles radial loads up to 4972 lbf and can spin at speeds up to 34,000 RPM, thanks to its phenolic cage and grease lubrication. Its 15° contact angle ensures stable performance under angular loads.

The sealed design keeps contaminants out, while the moderate preload (Class C) reduces vibration. It comes as a matched set of two bearings (DB arrangement) for balanced performance.

Ideal for high-speed applications like machine tool spindles or precision equipment. Works in temperatures from -30°C to 110°C and weighs just 0.24kg. Compliant with P4A tolerance class for accuracy.

Interchangeable with SKF bearings, making replacements straightforward. A reliable choice for demanding industrial or technical uses.
