2/11/2019· by Duane Ausherman. This page is about the BMW motorcycle models R26, R27, R50, R60, R69, R50/2, R60/2, R50S, R69S. Earles forks, often called leading link suspension, were introduced on BMWs in 1955. They were specifically designed for use on a bike with a sidecar. They are known for providing a soft ride and being extremely robust.
TIMKEN tapered roller bearing mounting, fitting and setting - Nodes bearing
As a result, TIMKEN tapered roller bearings are normally adjusted against a second bearing. They can be mounted in either a direct or indirect mounting arrangement shown as follows. For appliions where a direct mounting arrangement is used and the outer ring is used to adjust the bearing setting, the outer ring is usually set in position by an outer-ring follower or mounted in …
