When are custom couplings the best choice?

Randy Kingsbury, mechanical engineer and vice president of sales and marketing at Helical Products Company, tells us when a custom coupling might make the most sense for a motion system.

“The one thing I can say is our most expensive part is a custom part and our least expensive part is also a custom part. That gives some perspective that it doesn’t necessarily mean it’s going to be more expensive. The key is going into an application and looking if there’s other features or components that can be integrated into a coupling. When you do that, rather than buying a standard coupling and buying the associated components that maybe mount on either side of it, all these components can be machined into one solution.

We have machined specialty shaft shapes, flanges, gears, lever arms and more into a single piece solution so you do not have to buy a standard coupling and manufacture those additional components. Engineers are looking to manage their efficiencies by having a part where they are combining two, three, four or more parts. This saves them from managing many separate drawings, quotes and purchases from several vendors. Additionally, there is the savings of not having to invest manpower in assembling the various parts because the custom coupling is ready to drop into the assembly.”
