Application story 1: Challenge: A Helical customer had planned to use the AE087 or AE100 to connect a potentiometer to a control lever. The operating atmosphere included both salt and dirt, plus high parallel misalignment potential. They wanted to use a “D” bore to fasten the lever to a shaft, then connect the coupling to […]

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 […]
How do operating conditions impact coupling material choices?
When we have a job to do in a harsh work environment, stress builds quickly and it affects our efficiency. The coupling in your design is no different. Certain operating condition require specific coupling construction materials. Here, Randy Kingsbury, mechanical engineer and vice president of sales and marketing at Helical Products Company, explains some common […]
How do I avoid selecting an oversized coupling?
Less is more. Or, at least, more in not more. When your coupling selection is too big for its motion system britches, at best, your losing efficiency. Stepping up a size to a coupling that it slightly larger than necessary isn’t always going to cause a catastrophic failure, which is why we often let it […]
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. […]
When should you select a custom coupling?
By Mike Santora “If it ain’t broke, don’t fix it”— an old phrase perhaps most appropriate in reference to the coupling selection for a future design. With time constraints moving at the speed of commerce, designers go with what they know has worked in the past. That’s a legitimate argument. Plus, there is no reason […]
