Super Precision Angular Contact Ball Bearings 7013 CD/HCP4ADT

Super Precision Angular Contact Ball Bearings 7013 CD/HCP4ADT

The 7013 CD/HCP4ADT is a super precision angular contact ball bearing with a 65mm bore and 100mm outer diameter, crafted from chrome steel and ceramic balls for durability. It handles radial loads up to 15210 lbf and reaches speeds of 31000 RPM, making it suitable for high-performance applications.

Its 15° contact angle and matched arrangement of two bearings ensure smooth operation under angular loads. The phenolic cage adds strength while keeping the weight manageable at 0.72kg.

This bearing comes pre-lubricated and operates efficiently in temperatures from -30°C to 110°C. Ideal for precision machinery like spindles or CNC equipment where accuracy and speed are crucial.

Interchangeable with SKF bearings, it meets P4A tolerance standards for reliable performance. The open design allows for easy maintenance and inspection.
