Super Precision Angular Contact Ball Bearings S71903 CD/P4ADGA

Super Precision Angular Contact Ball Bearings S71903 CD/P4ADGA

The S71903 CD/P4ADGA is a super precision angular contact ball bearing with a compact 17mm bore and 30mm outer diameter, crafted from high-grade chrome steel. Its 15° contact angle and sealed design ensure smooth operation under angular loads.

With a dynamic radial load capacity of 1521 lbf and speeds up to 85,000 RPM, it performs reliably in high-speed applications. The phenolic cage and grease lubrication reduce friction for quieter running.

This bearing comes in a universal matched set of two, allowing flexible arrangements like back-to-back or face-to-face mounting. Ideal for precision machinery, spindles, or tools requiring tight tolerances.

Weighing just 0.034kg, it meets P4A tolerance standards and operates between -30°C to 110°C. Interchangeable with SKF bearings for easy replacement.
