Radial bearing

From RC Helicopter Wiki

A radial bearing is a rolling element bearing designed to take radial loads.

It consists of two ball races separated by ball bearings. The inner race supports the shaft that runs through it, while the outer race is typically press-fit into a bore. The ball bearings may be held in a bearing cage to reduce the number needed and reduce friction in lightly-loaded bearings.

Radial bearing can often be found supporting the main mast and tail shaft, and also in in the main blade grips.
