Super Precision Angular Contact Ball Bearings 7022 ACDGA/HCP4A

Super Precision Angular Contact Ball Bearings 7022 ACDGA/HCP4A

The 7022 ACDGA/HCP4A is a super precision angular contact ball bearing with a 110mm bore and 170mm outer diameter, crafted from chrome steel for durability. It handles radial loads up to 23400 lbf and operates smoothly at speeds up to 16250 RPM.

Its 25° contact angle and ceramic balls reduce friction, while the phenolic cage ensures quiet performance. The bearing comes pre-lubricated and works in temperatures from -30°C to 110°C.

Designed for precision applications, it fits universal matching sets for back-to-back or face-to-face arrangements. Ideal for high-speed machinery like spindles or CNC tools where accuracy is key.

Weighing 1.63kg, it meets P4A tolerance standards for reliable performance. Compatible with SKF bearings for easy replacements.
