Shaft Mounting Adapters

picture of Rotomation Shaft Mounting Adapter (SMA)


Rotomation shaft mounting adapters (SMA) are designed specifically to provide our customers a simple, accurate way to adapt their load to our actuators (shown in the Part Number table to the right). Our SMAs are available with standard mounting hole patterns ('W' option) or blank ('N' option) for easy customization in your own shop or to your specification in our CNC machine shop. They are made out of clear-anodized aluminum alloy and come with all necessary hardware. A reference bore on its top face, concentric with its shaft bore, makes customization an easy task. We install them onto our actuators if ordered together for shipping. Optional male or female pilots, accurately machined to your specified diameter, make it easy to install your tooling exactly on the center of rotation.



  • Stocked with standard hole patterns or plain, both with center tapped hole and reference c'bore concentric with shaft bore within .001 TIR
