It goes without saying that there are a lot of factors that go into selecting the right lead screw for your linear motion application. In a previous post, we told you about the importance of critical speed, which is defined as the speed that excites the natural frequency of the screw.

There are a variety of factors that must be considered before screw selection is determined in any type of application. One factor that should not be overlooked when it comes to selecting lead screws is critical speed. Lead screws, like any object in our environment, have a natural frequency.

Although lead screw end machining is not required for every application, the vast majority of applications do involve some sort of modification to one or both of the screw's ends. Here, we discuss some of the common elements that go into end machining, some related terms and other concepts that should be considered when utilizing a lead screw in your linear motion application.

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.

Regardless of the details of any given application, there are some pretty important design considerations that should be addressed each and every time you are considering lead screws as a means of linear motion. In this post we will explore four critical design elements that must be properly addressed to achieve success.

Acme lead screw assemblies are the preferred choice of many when it comes to linear motion applications, partially because they're very flexible, coming in "many flavors" so to speak. One example of this is simply how many material combinations are available between the screw and the nut.

You already know that lead screws are quickly cementing themselves as the preferred choice among product developers for use in linear motion applications.

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

If you’re an engineer, you already know about how important lubrication is to the long-term performance and reliability of lead screw assemblies. Lubrication repels water, provides corrosion resistance, and lowers the coefficient of friction.

There are a lot of reasons why acme screws are the preferred choice when it comes to linear motion applications. The popular trapezoidal screw with a 30-degree thread angle, which works to convert rotary motion into linear motion, boasts attractive features such as quiet operation, affordability, precision and a reduction in regular maintenance compared to the alternatives.
