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.

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.

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?

Our Helix H10X™ coating is now available. We have debuted a new PTFE coating in order to ensure an even longer life of your lead screw. Below are the top 10 reasons why our H10X™ coating is an improvement:

Getting some fresh air is always a good idea right? It wakes you up, refreshes you or even changes your mindset. But what happens when the air starts to get stale?

Twin lead screws from Helix Linear Technologies are designed to produce dual opposing motion using a single drive system. This one-piece screw delivers simultaneous right and left movement from a centerline. Ideal for high-performance applications with low duty cycles or manual drive operation, the advantages of using twin lead screws include easy installation and elimination of alignment problems.

As you know, the performance of trapezoidal screw assemblies doesn't just rely on the type of screw used, but in matching the given screw with the proper nut.

The number of medical imaging systems continues to grow at a projected annual rate of 6.8 percent, and linear motion control systems have become vital to the successful development, advancement, and deployment of these important pieces of medical equipment.
