Super Precision Angular Contact Ball Bearings 7214 ACD/HCP4A

Super Precision Angular Contact Ball Bearings 7214 ACD/HCP4A

The 7214 ACD/HCP4A is a super precision angular contact ball bearing with a 70mm bore and 125mm outer diameter, crafted from chrome steel for durability. It handles radial loads up to 14918 lbf and spins smoothly at speeds up to 19000 RPM.

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

Designed for precision applications, it meets P4 tolerance standards (ABEC-7) for accurate performance. Ideal for high-speed machinery like spindles or CNC equipment where angular contact is needed.

Weighing 0.95kg, it’s robust yet manageable for its size. Compatible with SKF bearings, making replacements straightforward.
