Compact option for linear motion

Equipment designers and engineers now have an even more compact option for their linear motion applications.

Servotechnic has released a Size 8 noncaptive linear actuator from Haydon Switch, the latest addition to its growing hybrid motor line.

Equipment designers and engineers now have an even more compact option for their linear motion applications.

The new size 8 linear actuator occupies a minimal 21mm space and includes numerous patent pending innovations that provide customers high performance and endurance in a very small package.

In fact, Haydon's new size 8 is claimed to be by far the smallest commercially available hybrid linear actuator on the market today.

In the noncaptive linear actuator design, the lead screw runs axially through the centre of the motor and must be restrained from rotating for proper operation.

This is normally accomplished by attaching the screw to a nonrotating member of the mechanical assembly.

As the internal threaded rotor rotates the lead screw will move axially but will not rotate.

This design is especially suited for long linear travel requirements and applications where the lead screw is secured at both ends and the motor translates along the lead screw.

When incorporating the latter approach, the motor must be prevented from rotating.

This non-captive hybrid linear actuator is available in a wide variety of resolutions ranging from 0.0015 to 0.04mm per step and delivers thrusts of up to 44.5N without compromising long life or cost.

Built for long life (several million cycles) and superior performance, the size 8 linear actuator features engineering thermoplastics in the rotor drive nut and a stainless steel Acme lead screw, which have made the Haydon products so popular.

With this patented design, quiet and maintenance free operation are ensured.

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.

In addition to standard configurations, Haydon can custom design this motor to meet specific application requirements.
