Super Precision Angular Contact Ball Bearings S7006 ACEGA/HCP4A

Super Precision Angular Contact Ball Bearings S7006 ACEGA/HCP4A

The S7006 ACEGA/HCP4A is a super precision angular contact ball bearing with a 30mm bore and 55mm outer diameter, crafted from chrome steel for durability. It handles radial loads up to 1989 lbf and spins at speeds up to 71,500 RPM, thanks to its ceramic balls and phenolic cage.

Its sealed design keeps grease in place, reducing maintenance needs, while the 25° contact angle ensures smooth operation under angular loads. The bearing operates reliably in temperatures from -30°C to 110°C.

This model is interchangeable with SKF bearings and comes in a set of two, suitable for universal matching in back-to-back, face-to-face, or tandem arrangements. Ideal for high-speed applications like machine tool spindles or precision instruments.

Weighing just 0.11kg, it’s lightweight yet robust, meeting P4A tolerance standards for exceptional accuracy.
