Helix Linear Blog - Acme Screws, Lead Screws, metric lead screws, Linear actuators

Although the term “linear actuator” can be defined broadly as any mechanical device that converts energy into controlled, straight-line motion, the definition narrows in the context of devices used for medical treatment and biomedical/chemical research.

After you have selected the right lead screw for your application, it becomes a matter of choosing the best nut to meet the demands of your particular application.

One of the benefits of lead screw assemblies is how easily they can be customized. Engineers have the option of working with a variety of materials from stainless steel, alloy steel, aluminum, titanium, and bronze. The manufacturing methods range from rolled, ground, machined...and molded?

There are more hospital beds than nurses and doctors in any given hospital. As the gap continues to grow, so does the need for more efficient, automated hospital beds to help save time and resources.

When it comes to actuators for motion control applications, there are several types to choose from. These include pneumatic, hydraulic, electric, or electro-mechanical.

The use of syringe pumps for medical treatment and chemical/biomedical research has substantially increased in recent years. The most common application for these small infusion pumps is to gradually administer intravenous medications to patients, including pain-killing analgesics, nausea-suppressing anti-emetics, and other drugs.

Helix has recently introduced its precision miniature lead screw designs for light load medical device design and applications that deliver fast speed and close tolerance positioning. Designed for compact applications that require the dual ability to be fast and precise - ideal for accurate positioning requiring a rapid approach and retraction.
