Super Precision Angular Contact Ball Bearings 7012 ACE/HCP4ADBA

Super Precision Angular Contact Ball Bearings 7012 ACE/HCP4ADBA

The 7012 ACE/HCP4ADBA is a super precision angular contact ball bearing with a 60mm bore and 95mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 5850 lbf and spins smoothly at speeds up to 35,000 RPM.

Its 25° contact angle and matched DB arrangement provide excellent stability for angular loads, while the phenolic cage ensures quiet operation. The extra-light preload (Class A) enhances precision in demanding applications.

This bearing is ideal for high-speed machinery like spindles or CNC tools, where accuracy and low friction are crucial. It operates reliably in temperatures from -30°C to 110°C.

Weighing 0.78kg, this set includes two bearings for balanced performance. Compliant with P4A tolerance standards, it’s interchangeable with SKF equivalents for easy replacement.
