Rotary Actuators

DURA-TAC SRA Series of rack driven rotary actuators provide a durable and compact approach to automatic work rotation.


DURA-TAC SRA Series have a compact, square body design to allow use in tight space applications. The output table is supported by two bearings to provide high loading capacity and a steady durable unit. The rack and pinion design provides zero backlash rotation in both directions and creates high torque and fast cycle times. Built in, adjustable hard-stops provide accurate rotation and prevent pinion damage. The bodies are sealed and require no lubrication. The units are fully field serviceable with available seal kits to reduce unwanted downtime and costs. The series also has available sensors to monitor rotation.


DURA-TAC SRA Series can be mounted and located in any plane with provided mounting holes and dowel pin holes. The main body contains both tapped holes and counterbored clearance holes for cap screws. The rotating table has tapped holes for mounting and slip fit dowel holes for location.

The SRA series of rotary actuators are perfect for
any applications where precise and repeatable rotary motion is required
