Double Stack Hybrid Linear Actuator from Haydon
External linear actuator.
Waterbury, CT — Haydon Switch & Instrument, Inc. has introduced its 28000 series (Size 11) double stack external hybrid linear actuator. The rotating acme stainless steel lead screw is incorporated into the motor's rotor. Shaft-to-lead-screw couplers are not needed with this design, thus saving time, money and labor during assembly into the final application assembly.

The new external linear actuator replaces four different components — a motor, coupler, lead screw and nut. The nut on the new external linear actuator uses the same high performance engineering thermoplastics as the rotor drive nut of the company's non-captive and captive designs. According to the company, this feature ensures trouble-free, exceptional long life operation for use in high precision applications.

The double stack external hybrid linear actuator is available in a wide variety of resolutions ranging from 0.000125-in. (0.003175mm) per step to 0.002-in. (0.0508mm) per step and delivers thrusts of up to 30 lbs. (133 N) without compromising long life or cost. A standard external linear has 4-in. of visible lead screw, however lead screw length and termination, as well as external nut design, can be customized to fit specific application requirements. In this design, the lead screw is an integral part of the motor with a mating nut translating along the screw. As the motor steps, the lead screw rotates but does not advance. This is the best overall design approach for obtaining linear travel in confined spaces. The lead screw ends can be machined to allow the use of outboard bearing support for long lead screw lengths.

Applications requiring precise positioning and rapid motion are best suited for this motor. Typical applications include medical equipment, X-Y Tables, automation of any kind, valve control and many more.
