A new design of Size 34 hybrid external linear actuator uses a rotating stainless-steel acme lead screw, which is incorporated directly into the motor’s rotor. Shaft to lead screw couplers are not needed with this design, thus saving time, money and labour during application assembly. The external linear actuator replaces four different components – a motor, coupler, lead screw and nut. The nut on the external linear actuator uses the same high-performance engineering thermoplastics as the rotor drive nut of HSI’s noncaptive and captive designs. This feature is designed to ensure trouble free, long-life operation for use in high-precision applications. Typical applications include packaging equipment, industrial equipment, x-y tables, automation of any kind, valve control and many more.
