Super Precision Angular Contact Ball Bearings 71804 CD/P2DBB

Super Precision Angular Contact Ball Bearings 71804 CD/P2DBB

The 71804 CD/P2DBB is a super precision angular contact ball bearing with a 20mm bore and 32mm outer diameter, crafted from high-quality chrome steel. It features a 15° contact angle and comes in a matched pair (DB arrangement) for balanced performance.

This bearing handles radial loads up to 1404 lbf and reaches speeds of 100,500 RPM, thanks to its phenolic cage and lubricated design. Its P2 tolerance class ensures exceptional accuracy for precision applications.

The open seal type allows for easy maintenance, while the light preload (Class B) reduces vibration. Ideal for high-speed spindles or precision machinery where tight tolerances are crucial.

Weighing just 0.036kg per bearing, this set operates smoothly between -30°C to 110°C. It’s interchangeable with SKF bearings, offering a reliable alternative for demanding setups.
