Helix Linear Technologies Blog | Articles, how-tos and information on the latest linear motion topics.

We are laser focused on making it easier for engineers to use our lead screws and linear actuators. Our new site has calculators, CAD Models, Part Number Configurators, Case Studies and many great videos.

Backlash (lash) is the relative axial clearance between a screw and nut without rotation of the screw or nut. Lash will always increase with use. Helix has developed several unique ways to reduce or remove the lash between the screw and nut.

The Acme thread form, established over 100 years ago, replaced square thread screws. Square thread screws had straight-sided flanks and were difficult to manufacture, so that makes the Acme thread form a great improvement.

Acme lead screws are a desirable piece of machinery. What makes them so great? Some of the reasons are: no braking system required, anti-backlash, low maintenance, and cost effectiveness.

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.

Helix Profile Rail Linear Actuators feature smooth, clean and quiet linear positioning. The PRA linear actuator utilizes a precision ground profile rail for guidance to deliver pitch, roll and yaw guidance. We compiled the top profile rail systems and blocks questions we get asked.

Acme lead screws are increasingly the preferred solution for linear actuation. Lubrication for acme screws is just as important. Lubricant types fall into two categories: liquid and non-liquid. Liquid lubricants are petroleum-based mineral oils with 90% or higher base oil. Non-liquid lubricants – or, dry lubricants – are used when an oil-based lubricant is ineffective.

Linear actuators have a variety of applications depending on the industry. Helix Linear's actuators can be used for any application requiring linear motion. Our actuators are pre-engineered, assembled, tested and ready to use making it the best economical and time sensitive approach to low cost automation. While we’re sure you’re thinking, “That’s great!” And it is, we’re sure there are many more questions to answer so keep scrolling below to find your answers.

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?
