Helac Corporation: Translating Linear Piston Motion into Shaft Rotation



linear-Piston-Motion

Headquartered in Enumclaw, Washington, Helac Corporation is a leading designer and manufacturer of helical hydraulic rotary actuators and other construction equipment accessories. Since its founding in 1968, Helac Corporation has delivered over 500,000 actuators to satisfied customers all over the world. The company serves those in the agriculture, construction, energy, marine, military, mining, and truck markets. Designed to simultaneously function as a rotating device, mounting bracket, and bearing, Helac Corporation helical hydraulic rotary actuators are able to perform the roles of many other components, making them a cost-efficient choice. Engineered with an advanced, sliding-spine mechanism, Helac actuators translate linear piston motion into powerful shaft rotation. The actuators are comprised of a housing and two moving parts--the central shaft and piston. To rotate, helical spine teeth on the shaft lock up with the corresponding teeth on the piston’s inside diameter—much like a zipper. An additional set of helical spine teeth on the piston’s exterior diameter engages with the gear in the housing to complete the motion. Due to the compact design and simple installation of its products, Helac Corporation has been a favored supplier to U.S. military.

During the period spanning the years 2000 to 2013, Helac has been awarded fifteen contracts from federal agencies on behalf of the U.S. military. Helac products are built to survive the harsh environments of a maritime or land-based operation. ASAP Semiconductor is a leading distributor of Helac Corporation parts.
