Super Precision Angular Contact Ball Bearings 7012 ACEGA/HCP4A

Super Precision Angular Contact Ball Bearings 7012 ACEGA/HCP4A

The 7012 ACEGA/HCP4A is a super precision angular contact ball bearing with a 60mm bore and 95mm outer diameter, crafted from high-quality chrome steel. It features a 25° contact angle and ceramic balls for smooth operation.

With a dynamic radial load capacity of 3668 lbf, it handles high speeds up to 33,000 RPM. The phenolic cage ensures durability, while the extra-light preload (Class A) enhances precision.

Its open design allows for easy lubrication, and it operates efficiently in temperatures from -30°C to 110°C. The bearing is interchangeable with SKF models, offering flexibility in replacements.

Ideal for precision machinery like spindles or CNC equipment, this bearing comes in a matched set of two for versatile mounting options (back-to-back, face-to-face, or tandem). Weighing 0.39kg, it balances lightweight design with robust performance.
