In some electric actuator installations, the position of the motor housing, cable exit, or mounting holes can affect how easily the actuator fits into a project. This is especially common in compact assemblies where side-mounted motors or cables may interfere with surrounding frames, brackets, or enclosure walls. In some cases, we can customize actuators with rotated mounting holes before shipment; however, custom manufacturing fees may apply, and lead times can take up to 13 weeks. If your project requires a stock actuator and you are comfortable making this adjustment yourself, this step-by-step article explains how mounting holes may be rotated on select models.
Introduction
Please note that rotating the actuator mounting holes may affect its ingress protection rating and should only be done when environmental sealing is not critical to the application. Certain actuators may also have slightly different procedures depending on whether they were custom-ordered or if they were a discontinued version. Our current line-up of stock model actuators is the focus of this article, which is intended to give users an idea of how to rotate some of their rotatable mounting holes.
Front Mounting Hole
The standard procedure generally used for rotating the front mounting holes of most of our actuators can be followed for the following models of mini actuators:
Step 1:
Using a piece of leather or something similar to protect the shaft housing from the vice plates, clamp the shaft housing with just enough pressure to prevent it from slipping during the following steps.
Step 2:
Place a screwdriver into the stroke mounting hole.
Step 3:
Rotate the screwdriver counterclockwise to the 90° position. If this is the first-time rotating the mounting hole, some extra torque may be required.
Warning: Do not rotate mounting holes counterclockwise more than 1 turn.
Step 4:
Remove the screwdriver, and your stroke mounting hole rotation is complete.
Rear Mounting Hole
Unfortunately, there is no method available for rotating the rear mounting holes of the models below:
PA-14 & PA-14P
To have the rear mounting holes rotated for either the PA-14 or PA-14P, a separate base cover piece with the mounting hole rotated will be required. We offer the PRT-14-8B, which has the mounting point rotated 90°.
Step 1:
Completely remove the three base cover screws and washers by rotating them counterclockwise using a Phillips screwdriver.
Step 2:
Remove the old base cover by pulling it in the direction away from the rest of the actuator’s body.
Before:
After:
Step 3:
Place the new replacement base cover into position and secure it with the three base cover screws and washers below by rotating them clockwise using a Phillips screwdriver. Rotation complete.
IN SUMMARY
To summarize, many actuators may need their mounting holes rotated for certain installation conditions and space requirements. By using a few tools and spending some time to follow our step-by-step guides, you too can rotate the mounting holes of an actuator to the required positions.
