S3 Stepping Actuator

S3 stepping actuator
S3 Single Rack Stepping Actuator


The S3 stepping actuator is ideal for use in medium index tables with shot pins, conveyors, or as drives for roll feeders. The S3 provides unidirectional rotation in increments but unlike our X3 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 S3 has a fully integrated clutch-bearing assembly for solid support of the load.
