By Joyce Laird, contributing editor Understanding the application to create a perfect match is always the first step in any process. Understanding the parts that go into that application are the key to that perfect match. So, first it is important to understand what a conical clamping hub is. A conical clamping hub is a […]

Insert properties in precision grade elastomer couplings
By Joyce Laird, Contributing Editor Andy Lechner, Product Manager for R+W America, explains that it is important to look at how to break down the classifications of elastomer insert couplings to better understand how everything fits into industry use today. He says that elastomer insert couplings generally fall under one of two main classifications: “standard” […]
How does shore hardness relate to elastomer inserts in couplings?
By Joyce Laird, contributing editor Precision elastomer couplings are used for a variety of applications in which a customer may need backlash-free torque transmission, vibration damping, electrical isolation, and compensation of misalignment. These torsionally soft couplings have an adjustable stiffness and temperature range with the selection of the color coded elastomer insert or spider. Alex […]
What are some types of coupling shaft connections?
By Joyce Laird, contributing editor All couplings relate to the connection method between the coupling hub and mating shaft. Mike Parzych, Product Marketing Manager for GAM explains that within this area, there are many things to consider when selecting the proper mating connections. “Keyed couplings have a key slot machined into the hub that accepts […]
Proper coupling selection: What you need to know
Selecting the couplings for your motion system doesn’t exactly stretch the limits of your engineering degree. Which is exactly why most of us don’t dig deeper to see if we’re making the best choice. The following is from a presentation on coupling selection best practices from two leading industry experts. Randy Kingsbury, Vice President of […]
Replacement wind turbine couplings for drivetrains with capacities up to 5MW
Zero-Max Wind Turbine couplings are now available as an upgrade replacement for existing wind turbines and for OEM applications. Tested and proven under conditions simulating a 20-year load spectrum of continuous operation, Zero-Max turbine couplings handle torque spikes and high misalignment installations. Zero-Max couplings are designed with composite disk packs at both ends of a […]
How do you specify keyways?
By Joyce Laird, Contributing Editor Overview Andy Lechner, Product Manager for R+W America is an expert in this field. He explains that for specifying keyways, it must be noted that there are very well established standards for dimensions, which can be found in Machinery’s Handbook, or ANSI B17.1 for imperial dimensions and DIN 6885 for […]
The 5 best Oldham couplings videos on the web
Oldham couplings are considered a workhorse in light load, servo applications. With their electrical isolation potential, zero backlash and misalignment capabilities (okay, maybe not angular), Oldham couplings are a familiar face in motion control applications and general industrial equipment. In this list, we take a look at some of the best Oldham coupling videos on the […]
The best bellows coupling videos on the web
The bellows coupling is a ubiquitous motion systems component. As such, there is no shortage of videos about them on the web. So how do you sift through clips of all that hard metal milieu? Well, you let us do it for you. In this article you will find some of the best, most concise […]
The 4 best magnetic coupling videos on the internet
4. Magnetic Couplings EagleBurgmann In this video we see how the Burgmann Research and Development Department designs its magnetic couplings to handle applications with gas-loaded media… It’s more interesting than you think. The video begins with a brief recap of permanent magnets (and a rather neat demonstration with two magnets dancing in tandem on either […]
