Super Precision Angular Contact Ball Bearings 71907 CE/HCP4ADGA

Super Precision Angular Contact Ball Bearings 71907 CE/HCP4ADGA

The 71907 CE/HCP4ADGA is a super precision angular contact ball bearing measuring 35mm by 55mm by 20mm, crafted from chrome steel with ceramic balls for smooth operation. It handles radial loads up to 2812 lbf and spins at speeds up to 56,000 RPM, making it suitable for high-performance applications.

Its phenolic cage and open design ensure durability and easy maintenance, while the 15° contact angle provides stability under angular loads. The bearing comes pre-lubricated and operates efficiently in temperatures from -30°C to 110°C.

This model is part of a matched set of two bearings, allowing for universal matching in back-to-back, face-to-face, or tandem arrangements. Ideal for precision machinery like spindles or CNC equipment where accuracy is key.

Weighing just 0.13kg, it’s lightweight yet robust, meeting P4A tolerance standards for exceptional precision. Interchangeable with SKF bearings for easy replacement.
