Super Precision Angular Contact Ball Bearings S71909 CDGA/HCP4A

Super Precision Angular Contact Ball Bearings S71909 CDGA/HCP4A

The S71909 CDGA/HCP4A is a super precision angular contact ball bearing with a 45mm bore and 68mm outer diameter, crafted from chrome steel for durability. It features a 15° contact angle and ceramic balls for smooth operation.

This bearing handles dynamic radial loads up to 2925 lbf and spins at speeds up to 46,000 RPM, thanks to its phenolic cage and grease lubrication. Its sealed design keeps contaminants out, reducing maintenance needs.

With an extra-light preload (Class A) and P4A tolerance, it offers high accuracy for demanding applications. The bearing works in temperatures from -30°C to 110°C and weighs just 0.12kg.

Ideal for precision machinery like spindles or CNC tools, it can be paired in back-to-back, face-to-face, or tandem arrangements. Interchangeable with SKF bearings, it’s a versatile choice for high-performance setups.
