Customized Linear Motion Solutions from Haydon Kerk

Among these applications is a linear actuator used in a throttle control system designed specifically for harsh environments.

This particular linear actuator is used to control the power to a cement mixer aboard a piece of heavy construction equipment. The typical operating environment for this application ranges from extremely dry and dusty to extremely hot and humid with nearly every other possibility in between.

After getting an understanding of the base models offered by Haydon Kerk, the equipment manufacturer worked closely with the Haydon Kerk design engineers to modify a “base” actuator to fit the specific application. The end result is a completely sealed linear actuator that withstands dirt, debris, and moisture.

The actuator has a rear enclosure that houses and seals the lead screw and bearing assembly, a bellows between the adapter and sleeve, a cable gland between the rear cover and cable, and an electrostatic coating on the lamination stack that effectively creates a permanent seal. The actuator also contains integrated switches for extended and retracted positions.

This is just one example of the far-ranging customization capabilities offered by Haydon Kerk. Over the years, Haydon Kerk has designed thousands of application-specific solutions into a broad range of systems for medical devices, laboratory instrumentation, semiconductor fabrication equipment, communications equipment, and a host of other applications.
