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 […]
How do I prepare for a flexible coupling installation?
To gain some insight on using a rigid coupling to later install a flexible coupling we talked to Bobby Watkins of Ruland manufacturing company to learn more. Here is what he had to say. Here I’m going to talk about how to use a rigid coupling in order to align components in preparation for the […]
How do I evaluate shaft misalignment?
To gain some insight on evaluating and understanding shaft misalignment, we talked to Bobby Watkins of Ruland manufacturing company to learn more. Here is what he had to say. Here is just a quick tip for evaluating shaft misalignment. On some couplings, a good scale or straight edge is good enough to run it across […]
Can coupling misalignment cause vibration?
In this column, Bobby Watkins of Ruland Manufacturing explains the relationship misalignment and vibration. Not properly accounting for it can lead to premature coupling failure or system component failure. Clearly define your misalignment min and max early in the selection process. That choice can be of a great help in preventative maintenance. Misalignment again, introduces […]
What is the difference between steady state and max torque
Bobby Watkins for Ruland Manufacturing on steady state and max torque: The difference between steady state and max torque. In many applications, there is a motor, which has a maximum torque rating, but it’s never used. Some people like to size their coupling based on max torque, and the coupling still may be able to handle it, […]
What are some different styles of disc couplings?
Disc couplings are an excellent choice when selected for the proper application. We asked Bobby Watkins of Ruland Manufacturing to give us some insight on general coupling selection. The following is an excerpt from the disc coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. Specifically, Watkins covers different styles of […]
Are disc and bellows couplings similar?
Disc couplings are an excellent choice when selected for the proper application. We asked Bobby Watkins of Ruland Manufacturing to give us some insight on general coupling selection. The following is an excerpt from the disc coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. “Disc couplings. The disc coupling […]
What do I need to know before selecting an Oldham coupling?
Oldham couplings are an excellent choice when selected for the proper application. We asked Bobby Watkins of Ruland Manufacturing to give us some insight on general coupling selection. The following is an excerpt from the Oldham coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. Zero backlash Oldham couplings are […]
Do bellows couplings require precision alignment?
Bellows couplings are an excellent choice when selected for the proper application. We asked Bobby Watkins of Ruland Manufacturing to give us some insight on proper coupling selection. The following is an excerpt from the bellows coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. Bellows couplings are for precise […]
