Super Precision Angular Contact Ball Bearings 708 CE/HCP4ADGA

Super Precision Angular Contact Ball Bearings 708 CE/HCP4ADGA

The 708 CE/HCP4ADGA is a super precision angular contact ball bearing with an 8mm bore and 22mm outer diameter, crafted from chrome steel for durability. It handles radial loads up to 848 lbf and spins smoothly at speeds up to 110,000 RPM.

Its 15° contact angle and ceramic balls reduce friction, while the phenolic cage ensures quiet operation. The open design allows easy lubrication, and it works in temperatures from -30°C to 110°C.

This bearing comes in a matched set of two, suitable for universal mounting (back-to-back, face-to-face, or tandem). Ideal for high-speed applications like machine tool spindles or precision instruments.

Weighing just 0.022kg, it’s lightweight yet robust, with a P4A tolerance class for exceptional accuracy. Interchangeable with SKF bearings for easy replacement.
