Replace Bearings on Precision Rail Vehicles
Bearings can be removed and replaced if they become damaged or worn due to extended use
(refer to the maintenance documentation from the bearing manufacturer). Figure 46 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.

CAUTION
Strong Magnets
To avoid severe injury, people with pacemakers and other
medical electronic implants must stay away from the magnet
array on the vehicles (pucks).
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, such as fingers, between a
vehicle (puck) or magnet array and any ferrous material
or another magnet array.
• Vehicles (pucks) or magnet arrays not being used must be
secured individually in isolated packaging.
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.
