Figure 7-16: Precision Rail Vehicle to Rail Orientation
Installing Vehicles with Rails Removed
The bearings on Precision Rail vehicles are pre-set at the factory prior to shipment. The rec-
ommended, and easiest method for installing vehicles on a Precision Rail system is with one
rail removed, or during installation prior to fastening the last rail onto the system. This enables
all vehicles to slide onto the rail system without having to make major adjustments to the
bearings. For proper vehicle orientation, see
1.
Slide the felt tip of the lubricating applicator into the body of the applicator so it can
clear the rail (refer to
Replacing Lubricating Applicators on Vehicles
).
NOTE:
The felt tip contains a v-groove that must be oriented correctly to the rail. If
the v-groove does not align with the rail excess drag will be created and the
vehicle will not move freely along the rail.
2.
Slide the vehicle onto the rail with the eccentric bearings on the outside (stand side) of
the rails.
3.
Once the vehicle is properly positioned on the rail, slide it along both the straight and
curve rails to determine if the factory pre-load is satisfactory. The vehicle should move
smoothly along both straight and curve rails with little or no front-to-back or
side-to-side rocking or binding felt between the vehicle bearings and the rail.
NOTE:
Each vehicle’s factory pre-load (eccentric bearing settings) will vary slightly
and may or may not be appropriate out of the box for a particular transport
system. If a vehicle’s eccentric bearings require adjustment to improve the
vehicle’s movement along the rail, see
•
If the vehicle can be noticeably rocked from side to side or front to back, then
there is too much movement between the bearings and the rail and the bearings
