Electrical isolation from a coupling is a common need for many motion system designs. We spoke with Bobby Watkins from Ruland Manufacturing to help us identify one of the most common types of couplings for when you need electrical isolation in your next design. “Electrical isolation: We talked about that some of the designs that will […]
Periflex VN couplings for water pumping system application
A robust coupling solution was needed for a large diesel-powered, artificial lift water pumping system used to push water up and over the Andes mountain range in South America. The complex system used a series of diesel engine powered pump stations installed on the side of a mountain to push water 4,000 vertical feet. The […]

According to the newly released PTDA Voice of the End Customer report which includes quantitative and qualitative responses from over 1,200 customers of power transmission/motion control (PT/MC) products from a variety of industries, there are distinct differences in what end customers want from their distributors depending on the type of industry, the role of the […]
Do I need to worry about windup during my coupling selection?
Often confused with backlash, windup is easy to overlook when selecting couplings for a motion system. But windup is an important consideration that can cause real problems if not factored-in early in the design process. Bobby Watkins of Ruland Manufacturing gives us a few reminders for thinking about windup in during your selection process. “Windup […]
Are you overlooking duty cycle in your coupling selection?
Duty cycle is a critical but often overlooked consideration during the coupling selection process. Critical elements like types of motion, potential shock load scenarios, and start/stop situations should all be evaluated when selecting a coupling for your next motion system application. Here, Bobby Watkins of Ruland Manufacturing gives us some insight on what to look […]
How does inertia influence servo coupling applications?
We talked to Ruland Manufacturing’s Bobby Watkins to learn more about the role inertia plays in servo coupling applications. Here is what he had to say. “Failure most often occurs when maximum speed is exceeded. Every type of motion control coupling has a different max speed rating. It varies. It’s something to be mindful of […]
