A4 Rotary Actuator
The A4 incorporates all the design features that have made our 1 to 2-inch bore actuator line the standard in the industry for reliability and configurability. Floating pistons and a precision ground rack riding in replaceable sintered bronze bearings provide enhanced durability. The one piece, heat treated alloy steel pinion shaft is supported by large sealed ball bearings and it can be customized to suit your load. For double the output torque and zero backlash, consider our A42 rotary actuator. For the three-position version, see A42 3-position actuator.
