Super Precision Angular Contact Ball Bearings 707 CE/P4ADBA

Super Precision Angular Contact Ball Bearings 707 CE/P4ADBA

The 707 CE/P4ADBA is a super precision angular contact ball bearing with a compact 7mm bore and 19mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 702 lbf and spins smoothly at speeds up to 230,000 RPM.

Its 15° contact angle and extra-light preload ensure precise performance, while the phenolic cage offers quiet operation. The open design allows easy lubrication, extending its service life.

This matched set of two bearings (DB arrangement) is ideal for high-precision applications like machine tool spindles or dental equipment. It operates reliably in temperatures from -30°C to 110°C.

Weighing just 0.014kg, it’s lightweight yet robust for its size. Compliant with P4A tolerance class, it’s interchangeable with SKF bearings for easy replacement.
