Azimuth Roller Bearing

A simple teflon friction bearing used by some manufacturers offers a rather stiff motion that makes tracking at high magnifications difficult. This becomes particularly obvious when the telescope is pointed near the zenith so that the lever arm becomes very short. In this position tracking is almost impossible in some Dobsonians!

This modern industrial roller bearing is for a very easy movement. Metal plates above and below the bearing prevent the rollers from sinking into the softer wood of the rocker box, so the movement will remain smooth even after years of use.

Scope of delivery:

-- industrial roller bearing system
-- 2 metal plates
