S1 Stepping Actuator

S1 stepping actuator
S1 Single Rack 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.
