Super Precision Angular Contact Ball Bearings 7012 FEGA/HCP4AH1

Super Precision Angular Contact Ball Bearings 7012 FEGA/HCP4AH1

The 7012 FEGA/HCP4AH1 is a super precision angular contact ball bearing with a 60mm bore and 95mm outer diameter, crafted from chrome steel for durability. It features ceramic balls and a phenolic cage, ensuring smooth operation at high speeds up to 35,000 RPM.

With an 18° contact angle, it handles both radial and angular loads effectively, supporting up to 3780 lbf dynamically. The extra light preload (Class A) enhances precision, making it ideal for high-accuracy applications.

Its open design allows for easy lubrication, while the P4A tolerance class guarantees consistent performance. The bearing operates reliably in temperatures from -30°C to 110°C.

Weighing 0.39kg, it’s suitable for paired arrangements (back-to-back, face-to-face, or tandem). Perfect for machine tools, spindles, or other precision machinery where low friction and high-speed performance are key.
