Super Precision Angular Contact Ball Bearings 7015 CD/P4ATBTA

Super Precision Angular Contact Ball Bearings 7015 CD/P4ATBTA

The 7015 CD/P4ATBTA is a super precision angular contact ball bearing with a 75mm bore and 115mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 25650 lbf and reaches speeds of 22000 RPM, making it suitable for high-performance applications.

Its 15° contact angle and extra light preload ensure smooth operation with minimal friction. The phenolic cage adds strength while keeping the bearing lightweight at 1.88kg.

Designed as a matched set of three bearings (TBT arrangement), it offers stability for complex loads. Ideal for precision machinery like spindles or CNC equipment where accuracy is key.

The open design allows easy lubrication, and it operates reliably in temperatures from -30°C to 110°C. Interchangeable with SKF bearings for convenient replacements.
