In Reply to: Help Me Understand...Bearing Pre-load posted by Erik in WI on July 20, 2006 at 17:11:31:
Tapered roller bearings run with axial load applied all the time. This load is a combination of the loads applied from the shaft they are controlling, and pre-load. Pre-load is applied by rotating adjusters, Crushing a special sleeve, removing or adding shims, or shim gaskets. The result is to put a partial load on the rollers even when there is no load on the shaft. Tapered roller bearings need as much as 2-to-5% of their rated max load used as pre-load to keep them aligned and the shaft located. The system load is measured in several ways some times with nut tightness on a shaft, sometimes by rotational force on the assembly, and sometimes by measurment and mathmatics. The only way a seperate preload could be involved is if the case was distorted by the loading of the first shaft. Not a best design situation, and not applicable to two axles on the tractor (my opinion) JimN
