Super Precision Angular Contact Ball Bearings 7005 CD/P4ADBD

Super Precision Angular Contact Ball Bearings 7005 CD/P4ADBD

The 7005 CD/P4ADBD is a super precision angular contact ball bearing with a 25mm bore and 47mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 3510 lbf and operates smoothly at speeds up to 103,000 RPM.

Its 15° contact angle and heavy preload (Class D) ensure stable performance under angular loads. The phenolic cage offers quiet operation and long service life, even in temperatures from -30°C to 110°C.

This matched set of two bearings (DB arrangement) is ideal for high-precision applications like machine tool spindles or robotics. Weighing just 0.16kg, it’s lightweight yet robust for its size.

Interchangeable with SKF bearings, it’s a reliable choice for replacements or upgrades in demanding industrial settings.
