By Zak Khan A locking device is designed to prevent mated shafts and components from loosening out of place when they are subjected to movement, varying temperatures, vibrations, stresses, and other operating conditions. They are critical components, as they often ensure the safety of the system. They appear frequently in systems that require coupling various […]

Couplings see technological and economic growth
Two industry trends could spur change in the application of couplings over the next few years. The first relates to technology improvements for the components themselves. Here, advanced materials are improving couplings in an array of industries. The second is economics-influenced market growth. Expect to see enduring gains in the use of motion designs through […]
Motion systems application examples: Shaft collars and where they work
By Mike Santora Shaft collars are part of nearly all types of moving machinery—including designs for mechanical, medical, aerospace, automotive and industrial industries. In electric-motor-driven designs, they’re most common at the gearbox and motor assemblies. Shaft collars satisfy three basic functions: set shaft position space components on shafts limit shaft movement As such, they commonly […]
Flexible Couplings-Common Mistakes in Assembly and Maintenance
By: Stan Riddle, VibrAlign In my job, I teach shaft alignment training to over 500 people per year, in dozens of facilities-everything from manufacturing, to mining, to energy, to municipalities. All of these facilities have one thing in common-they use the same types of couplings. And many of them fail before their time. This article […]
Quick Tips to Avoid Coupling Failure
by William Hewitson, Vice President of Manufacturing and Engineering, Ruland Manufacturing Co., Inc The keys to avoiding coupling failure are correct coupling selection using all application design criteria, proper installation, and periodic system maintenance. Mechanical couplings typically connect rotating shafts to facilitate the transfer of rotary motion and torque. As with all mechanical devices, a […]
Servo couplings for a wide variety of applications
Rigid couplings have high torque capacity, torsional stiffness, and zero backlash. Ruland Manufacturing Co., Inc. straight bore rigid couplings have precision honed bores for proper fit and alignment. Proprietary Nypatch coating is used on hardware to resist vibration and maintain holding power. Two-piece styles feature opposing screws for balancing, reducing vibration at higher speeds. Ruland […]
Zero Backlash Jaw Couplings from Ruland
Ruland offers zero backlash jaw couplings for the demanding requirements of start and stop machine vision systems used in industries such as semiconductor, medical, solar, and packaging. The dampening characteristics of Ruland’s jaw couplings reduce settling time and shock loads, making them ideal for these environments. Jaw couplings are a three piece design comprised of […]
VULKAN Couplings unveils New Integrated Shaft Coupling Design
VULKAN Couplings (www.vulkan.com) has unveiled a new innovation of the Rato DS coupling that is directly connected to a composite shaft. Aside from being a torsional coupling, the combination of high radial stiffness and low bending and axial stiffness makes the Rato DS ideal to work as an integrated misalignment coupling when it is rigidly […]
Low weight, low inertia torque limiter
By Tobias Wolf, Product Engineer, R+W GmbH and Andrew Lechner, Product Manager, R+W America. The concept of weight reduction through the use of high tech materials is not a new one. But for those involved in the design of motion control and automation systems, the elimination of excess mass and inertia is often the difference […]
Zero Backlash Coupling Ideal for Belt Driven Linear Actuators
Due to greater demands in modern machine design and construction, R+W has developed its EK7 series of SERVOMAX Zero Backlash Elastomer Couplings. This coupling was specifically designed to mount to hollow bores with an expanding tapered clamping element, making it ideal for belt driven linear actuators. The EK7 provides design engineers with a number of […]
