S1 Stepping Actuator  

The S1 is our smallest stepping actuator but it shares the same traits of its larger counterparts. The S1 provides unidirectional rotation in increments but unlike our X1 indexing actuator, it does not have positive stopping capability. The load will coast to a stop unless acted on by an external force. Unlike competitive products with add-on clutch housings, the S1 has a fully integrated clutch-bearing assembly for solid support of the load. For increased torque output, consider our S2 stepping actuator.

Rotomation S1 Stepping Actuator will provide you with an incremental drive that will rotate in one direction and coast to a stop as the inertial load decelerates


  • Extremely configurable to fit your specific needs

  • Optional rotation adjusters, bumpers, flow controls, cushions*1

*1Cushion on drive requires shaft/load to have some drag to properly affect load. Cushion on reset will NOT affect load.
