*Below is an excerpt from a Design World webinar presentation by Andy Lechner of R+W America. Here, Lechner covers some best practices for handling coupling installation in precision motion control applications. Coupling alignment is important in smaller devices, especially when there’s precision or dynamic motion that needs to be transmitted. If you think about the […]

How to install a torsionally soft coupling
Edited by Mike Santora *This is an excerpt from a Design World Webinar presentation by Ed Cole of Ringfeder Power Transmission. …Our TNR series torsionally soft coupling is typically installed on the flywheel of a diesel engine. The TNR is usually installed on pump packages, compressor packages, gen-sets, other specialty packages and fire-pumps. The primary […]
The 3 best beam coupling videos on the internet
Beam couplings are an essential motion system component for torque transmission and misalignment compensation. In this list, we’ll cover a few of the most informative, most viewed and most valuable beam style coupling videos on the internet. 1. How to Install a Beam Coupling | RULAND Great beam coupling performance starts with proper installation. Might […]
Conical clamping hubs add protection to high torque applications
By Joyce Laird, contributing editor Two Categories of Connections In the world of power transmission and motion control, the different methods of connecting rotating components can be divided into two categories: positive form fit connections, and frictional connections. “Positive form fit connections are the more traditional means, and the technology dates back some centuries,” Andy […]
What is an electrodeposited nickel bellows coupling?
What Makes This Technology Unique? The foremost quality of electrodeposited nickel bellows couplings is that they flex to fit misaligned shafts and yet remain torsionally stiff. “What do a micro-precision silicon wafer cutter, a surgical microscope focusing mechanism, and a target sighting system for an M1A2 Abrams tank all have in common?” Lori Lyons, marketing […]
Should I choose a keyed or keyless coupling for this application?
By Joyce Laird, contributing editor Taking a look at keyed and keyless couplings from the applications point of view puts the choice in a very clear perspective. Both are needed in many applications and both bring specific features and benefits. Bobby Watkins, V.P. Sales. Ruland Manufacturing says that the first thing to look for when […]
What is a conical clamping hub?
By Joyce Laird, contributing editor Understanding the application to create a perfect match is always the first step in any process. Understanding the parts that go into that application are the key to that perfect match. So, first it is important to understand what a conical clamping hub is. A conical clamping hub is a […]
Insert properties in precision grade elastomer couplings
By Joyce Laird, Contributing Editor Andy Lechner, Product Manager for R+W America, explains that it is important to look at how to break down the classifications of elastomer insert couplings to better understand how everything fits into industry use today. He says that elastomer insert couplings generally fall under one of two main classifications: “standard” […]
How does shore hardness relate to elastomer inserts in couplings?
By Joyce Laird, contributing editor Precision elastomer couplings are used for a variety of applications in which a customer may need backlash-free torque transmission, vibration damping, electrical isolation, and compensation of misalignment. These torsionally soft couplings have an adjustable stiffness and temperature range with the selection of the color coded elastomer insert or spider. Alex […]
What are some types of coupling shaft connections?
By Joyce Laird, contributing editor All couplings relate to the connection method between the coupling hub and mating shaft. Mike Parzych, Product Marketing Manager for GAM explains that within this area, there are many things to consider when selecting the proper mating connections. “Keyed couplings have a key slot machined into the hub that accepts […]
