West Chicago, IL – R+W, a global brand of precision couplings for motion control and automation systems, has just opened a new US‐based manufacturing facility with expanded machining capabilities and assembly operations for its precision couplings and line shafts. The company relocated into the 30,000-square-foot facility in West Chicago, IL in late 2022, and is […]

As we ring in the new year, the Design World staff would like to present our most-read articles of 2022. 1. Best free analog circuit simulators Blogs and online forums catering to engineers often mention all kinds of free packages and services aimed at circuit designers. Trouble is, a lot of these free resources are…

The component manufacturing plant in Nizna, Slovakia, was renamed at the end of 2021 to be even more closely affiliated with R+W, and as of 15 August 2022, an additional managing director was recruited to strengthen the operations. Certain components for the precision couplings manufactured by German company, R+W, are supplied by the production plant […]

Maintenance-free and torsionally stiff connecting elements for smooth stable running For many decades engineers have turned to the flexible disc pack coupling for applications requiring maximum reliability and uptime, minimizing wear on adjacent equipment, and eliminating the need for lubrication or maintenance of the coupling itself.  Before disc couplings were invented, flexible couplings nearly always…

Where torques as low as 0.05 Nm are to be transmitted and shaft diameters as small as 1mm are to be connected, miniature bellows couplings (MK series) from R+W are the right choice. As a result of the trend toward miniaturization – for example, in medical technology, laboratory equipment, and micro-pumps – this product plays […]

Recording measurement data, with high precision and directly in the driveline, is now easy with R+W’s own integrated sensor technology built into proven couplings designs. With ARTIFICIAL INTELLIGENCE BY R+W, measurement data is recorded directly from the drivetrain in almost real-time. This was previously very difficult to achieve in drive technology because of the rotating […]

For the past 30 years or more, designers of highly dynamic servo drive systems have been turning to bellows couplings to optimize the stiffness, inertia, and smoothness of rotation in their coupling applications. When it comes to torsionally rigid couplings the stainless steel bellows wins in all three categories. Take for example high-speed camming of […]

Precision elastomer insert couplings offer technical advantages in a wide variety of power transmission applications. With the rigid jaw hubs machined from solid round bar stock, the torque density can be superior to that of almost any other type of backlash free flexible coupling, depending on the stiffness of the elastomer insert which is used. […]

Last night, at the inaugural LEAP Awards dinner gala in Costa Mesa, Calif., the winning company was announced in the Mechanical Category. The finalists created and incredible mix of mechanical component technology advances. In the category of Mechanical, the finalists were: CPC – Colder Products Company Ultra-Compact LQ2 Quick Disconnects R+W Coupling Technology World’s Largest Ball-Detent […]

Without processing plants for crushed stone and gravel, many large construction sites cannot operate on schedule. Jaw or impact crusher plants are facilities that break rock into crushed stone or gravel. The crushing ratio depends on the subsequent processing requirements. The output for large plants is several thousand tons of rock per hour. Machine downtime […]

  Well developed road and rail networks are an essential requirement for a sound and efficient infrastructure in any country. Therefore, the tunneling machine field within the heavy machine construction industry will have plenty of contracts in the coming years. R+W ST safety couplings have been integrated in the latest generation of tunneling machines. On […]

Depending on the application, the prevailing conditions for tunneling technology are extreme temperature ranges, heavy contamination, strong vibration, and continuous operation 24/7 all year long. The construction material is transferred to conveyor belts and transported several kilometers for processing. To transfer the high levels of torque to the main and auxiliary drives of the conveyor […]

By Sina Odenwald A coupling connects – simply put, a coupling is nothing other than a connection between two shafts. But shaft couplings can do more: · They transmit torque · They compensate for axial, lateral and angular shaft misalignment · They damp vibration · They also protect expensive equipment from overload This is explained […]

The areas of application for couplings are wide-ranging due to the variety of requirements in drive technology. Couplings must always be specifically selected according to their application and its requirements – this is the only way to ensure secure torque transmission and, if required, protection against damage and downtime from overload. A German manufacturer of […]

R+W has recently introduced two new smaller STN series safety couplings with conical clamping hubs, to bring heavy duty industrial style overload protection into midsize applications. The two new sizes, 2 and 5, cover disengagement torques ranging from 200 to 5,000 Nm, and shaft diameters from 45 to 80mm (1.750 to 3.125-in.). Taking advantage of […]

Having experienced increased demand for torsionally rigid disc pack couplings for use in explosion-protected atmospheres, R+W Antriebselemente GmbH has expanded its range of industrial couplings.
