Progressive Automations offers custom orders on all linear actuators.  We can modify actuators based on stroke size, force, dimensions, mounting holes voltage and wire length.  Different models will have different modifications available.  Currently the longest stroke we can produce is 40 inches for PA-02 and PA-19 models and 24 inches on all other linear actuator models.  The smallest force is 11 lbs and highest is 2000 lbs.  For PA-02 models we are able to rotate the mounting holes by 90 degrees.  The available custom voltage is 24 and 36 VDC while all in-stock product is 12 VDC.  The ability to modify the units creates a benefit for our customers, no need to modify the actuator yourself.  Get the product that fits your application and operates with the required specs.
