Replace Bearings on Precision Rail Vehicles
Bearings on the precision rail vehicles can be removed and replaced if they become damaged
or worn due to extended use (refer to the maintenance documentation from the bearing manu-
facturer). Figure 7-44 shows the location of each set of eccentric bearings and concentric
bearings for both the single array and dual array vehicles. The concentric bearings are located
closest to the magnet arrays and the eccentric bearings are located furthest from the magnet
arrays.
MAGNETIC FIELD HAZARD: Strong magnets in use.
To avoid severe injury, people with pacemakers and other
medical electronic implants must stay away from the magnet
array on the vehicles (pucks).
PINCH/CRUSH HAZARD: Strong magnets in use.
To avoid injury from strong magnetic attractive forces:
• Handle only one vehicle (puck) or magnet array at a time.
• Do not place any body parts (for example, fingers)
between a magnet array and any ferrous material or
another magnet array.
• Vehicles (pucks) and magnet arrays not being used must
be secured individually in isolated packaging.
NOTICE Strong magnets in use.
To avoid damage to watches, instruments, electronics, and
magnetic media, keep metal tools, metal objects, magnetic
media (for example, memory disks/chips, credit cards, and
tapes) and electronics away from the magnet arrays.
