Super Precision Angular Contact Ball Bearings 7003 CD/P4AQBCD

Super Precision Angular Contact Ball Bearings 7003 CD/P4AQBCD

The 7003 CD/P4AQBCD is a super precision angular contact ball bearing with a 17mm bore and 35mm outer diameter, crafted from durable chrome steel. It features a 15° contact angle and comes in a matched set of four bearings for heavy preload applications.

This bearing handles radial loads up to 4005 lbf and can spin at speeds up to 121,000 RPM, making it suitable for high-performance machinery. Its open design allows for easy lubrication, while the phenolic cage ensures smooth operation.

Designed for angular contact loads, it excels in applications requiring precise alignment and stability. The P4A tolerance class guarantees high accuracy, ideal for CNC spindles or precision tools.

With a temperature range of -30°C to 110°C, it performs reliably in various environments. Weighing just 0.15kg, it’s lightweight yet robust for its size, and is interchangeable with SKF bearings for easy replacement.
