Stainless steel oldham couplings are zero-backlash, can accommodate all forms of misalignment and have a balanced design, making them suitable for a wide variety of servo […]

We spoke with Bobby Watkins of Ruland manufacturing to get an overview of some basic coupling installation best practices. Ultimately, even if a coupling is properly selected, poor installation can cause failures. “Always be sure your selected coupling is used within its ratings. We estimate here at Ruland that less than 25% of the couplings […]

Torque wrenches are used to precisely install hardware to a preset torque. They simplify installation, prevent over torquing, and maximize performance in installations where joint tension is critical to component performance, such as a shaft collar or coupling. Operators will either set the wrench to the desired torque or purchase them with a preset torque […]

Many environmental considerations affect coupling selection. There is moisture, chemicals, and vacuum, to name a few. The different types of motion-controlled couplings have a different capability in handling different environmental considerations. You want to know moisture level, any chemical presence or if you’re dealing with a vacuum and you don’t want any outgassing, that’s an important […]

In the following video, Ruland Manufacturing’s Bobby Watkins talks about heavy-duty shaft collars. Watkins explains how an increased outside diameter impacts axial holding power and other shaft collar specifics. Ruland Manufacturing www.ruland.com

New Mountable Shaft Collars from Ruland Manufacturing offer • Shaft collars with flats and holes for easy mounting to adjacent assembles such as sensors. • Multiple shaft collars can be mounted to each other to install parallel or perpendicular shafts. • Mountable shaft collars can be used for guiding, spacing, stopping, mounting, and component alignment. […]

Ruland Manufacturing is now an authorized distributor for Controlflex couplings manufactured by Schmidt-Kupplung in Wolfenbüttel, Germany. This partnership will give Schmidt-Kupplung an expanded North American presence and Ruland a more complete zero-backlash coupling product line. Controlflex couplings have a compact balanced design, are electrically isolating, and have high misalignment capabilities, making them a suitable fit […]

This webinar was presented live on Tuesday, December 11, 2018. Click below to watch it on demand.      Why do I keep breaking couplings? Ever found yourself wondering this? This coupling crash course presented by coupling expert Bobby Watkins will teach you why couplings fail, best practices to avoid future failures, and installation tips…

Ruland has added a new accessory product line including key stock, hex keys and torque wrenches to assist with assembly and installation of shaft collars and couplings. Tools are available in a wide range of options from stock in Ruland’s Marlborough, Massachusetts factory. Ruland oversized key stock is pre-cut to fit inch and metric ASME […]

Understanding the myriad environmental variables a coupling might encounter is crucial during early the design stages of your motion system. We spoke with Bobby Watkins from Ruland Manufacturing to help us identify some of the environmental consideration design engineers should keep in mind. He gives a few real-world examples to explain. “Environmental considerations include temperature, […]

Ruland has expanded its offering of threaded shaft collars by adding inch and metric left hand threaded styles to give designers more flexibility to work with standard off the shelf components. They are available in one- and two-piece clamp styles in steel and stainless steel with bore sizes ranging from 1/8 to 2-1/4-in. and 4 […]

Shaft Collars…A Million Uses At Ruland Manufacturing, they have a running joke that there are a million different uses for shaft collars. Three years ago, they challenged themselves to find them. The company says the shaft collars that they have found in their travels have been fascinating — exercising on the Bondi Coogie beach walk […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

Bobby Watkins of Ruland Manufacturing on misalignment and vibration: Why is misalignment a concern?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 RPM […]

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, […]
