Lubrication
The wheel and pulley bearings are pre-lubricated for the life of the unit. No additional lubrication is
necessary.
Actuator Mounting
The ERV units should only be mounted down by way of the T-slots on the body of the unit. The endcaps
should never be used as mounting points. The mounting holes provided on the carriage as well as the T-
slots are designed to accommodate standard Parker Hannifin IPS mounting brackets in the 28mm and
40mm profile sizes (ERV56 and ERV80 respectively).
See the ERV product catalog for additional mounting gussets.
Roller Wheel Wiper Accessory
A roller wheel wiper accessory is offered for applications where large particles may accumulate on the wheel
rails. This is constructed of a felt pad on either end of the carriage which will wipe the rails before the
wheels pass over. Below is a parts layout for this option.
