Super Precision Angular Contact Ball Bearings 71818 CD/P4DBAVT105

Super Precision Angular Contact Ball Bearings 71818 CD/P4DBAVT105

The 71818 CD/P4DBAVT105 is a super precision angular contact ball bearing with a 90mm bore and 115mm outer diameter, crafted from durable chrome steel. Its compact 26mm width makes it suitable for space-conscious applications.

This bearing handles radial loads up to 8055 lbf and reaches speeds of 15000 RPM, thanks to its phenolic cage and 15° contact angle. It comes preloaded in an extra-light class for smooth operation.

The open design allows easy relubrication, while the matched pair (DB arrangement) ensures balanced performance. It operates reliably in temperatures from -30°C to 110°C.

Ideal for high-precision machinery like spindles or CNC equipment where accuracy is crucial. Weighing 0.56kg, it offers robust performance without adding bulk. Compliant with standard tolerance class N specifications.
