ER Series Rodless Actuator
ER Series Rodless Actuator
Product Introduction and Features
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.
ER Series Features
• Produced to hard metric ISO standards
• Three ISO mount sizes: 32mm, 50mm, 80mm
• Standard roller bearing carriage
• Square rail carriage option for greater load carrying capability
• Extruded, anodized aluminum body with t-slots for mounting switches and clamps
• Angular contact thrust bearings at rear of screw
• Polyurethane bumper at ends of travel
• Low-friction ball bearing nut and quality rolled ball screw option
• Low-friction burnished lead screw with bronze nut option
• Steel reinforced polyurethane drive belt (belt drives only)
• Integral sensing magnet
• High quality flexible couplings
• High performance stepper , servo and DC brush motors
• Designed for multi-axis connectivity (available from the Automation Actuator Division)
Motor Systems
• Microstepping systems
• DC Brushless servo systems with encoder or resolver feedback
• AutoDrive DC brush limit switch controller systems
• User provided AC or DC motor systems

ER Series Rodless Actuator
ER Series Form Factors
The ER Series Rodless Actuator is available in three basic form factors, each of which carries a separate exploded
view drawing and parts list. After determining your ER form factor, refer to the parts list section corresponding to that
form factor.

Motor Mounting Styles
The ER Series Rodless Actuator includes pre-mounted DC stepper, brushless servo or brush motors. Motors may
be mounted inline, or directly coupled to the screw shaft (screw drive) or pulley shaft (belt drive). Alternatively , motor
may be mounted in a variety of parallel (or reverse-parallel) configurations. Parallel mounting link the motorshaft and
actuator drive shaft through a timing belt and pulley system. Refer to the model code pages (pp. 6-7) and Catalog
1894, Electromechanical Actuator Products, for a detailed description of the many mounting possibilities. Each
motor mounting assembly may be applied to all ER Series types: screw and belt drive, roller bearing and square rail.
