PM-ER01/USA ER Series Rodless Actuator
Maintenance Instructions and Parts List
The ER Series Rodless Actuator combines a robust, modular design with a variety of options that allow it to be tailored to
many applications. With two load bearing carriage styles available on all actuator sizes and two drive types (belt and screw
drive), the ER Series may be ordered specifically designed for the application. Combined with a Parker Hannifin stepper,
servo or DC brush system, the ER Series becomes a fully programmable linear actuator system.
