Super Precision Angular Contact Ball Bearings 7007 CDGA/HCP4A

Super Precision Angular Contact Ball Bearings 7007 CDGA/HCP4A

The 7007 CDGA/HCP4A is a super precision angular contact ball bearing with a 35mm bore and 62mm outer diameter, designed for high-speed applications. It features a 15° contact angle and is made from durable chrome steel with ceramic balls for smooth operation.

This bearing handles radial loads up to 3510 lbf and spins at impressive speeds up to 56,000 RPM. Its phenolic cage ensures stability, while the extra light preload (Class A) reduces friction for efficient performance.

The open design allows easy lubrication, and it operates well in temperatures from -30°C to 110°C. Weighing just 0.13kg, it’s lightweight yet robust for precision machinery.

Ideal for applications like CNC spindles or high-speed motors where accuracy and speed are crucial. It can be arranged back-to-back, face-to-face, or tandem, offering flexibility in design.
