When precision machine drives are assembled without mounting pilots between the servo motor/gearbox and driven equipment, shaft misalignment becomes a key consideration in coupling selection. Most precision couplings are designed to compensate for a parallel shaft misalignment of between 0.1-0.2mm, which is perfect for piloted interfaces. When the connected components are mounted to different surfaces, […]

R+W MODEL BK8 flange-mounted precision bellows couplings
Increasing demands for high-quality motion transfer in compact and efficient machinery require that every component be evaluated, including connecting elements. When optimizing for highly dynamic motion, balance, and positioning accuracy, many mechanical designers are moving away from traditional shafted connections – opting instead for a more direct method of attachment for flexible joints. R+W has […]
Strong… Stronger… R+W disc pack couplings
New configurations and solutions for extreme conditions. Robust and compact: R+W disc pack couplings are torsionally stiff, maintenance-free, and reliable even in some of the most difficult operating environments, including steel works, high-performance dynamometers, and industrial pump and process equipment. Fully metallic and made from high strength materials, they frequently operate in temperatures ranging from […]

R+W: Coupling materials enable weight reduction up to 60%
The field of products in which an increase in speed and stiffness or energy savings can be achieved through a reduction in mass is very large. This area is not only limited to applications where lightweight construction has traditionally played an important role, such as in aerospace, but also includes production machinery such as industrial […]
R+W on the intelligent revolution in couplings for Industry 4.0
By Sascha Markert There are many cases where an expensive torque sensor would be excessive for measuring torque and speed. R+W Antriebselemente has launched a completely new alternative with its intelligent coupling. The product innovation presented here permits recording measurement data directly in the drive train, taking very accurate measurements and simultaneously user-friendly operation. Some […]
The R+W intelligent coupling
The “intelligent coupling” features direct recording of mechanical data in the drive train, taking accurate measurements through user-friendly operation. Some of the ideas underlying the Industrial Internet of Things (IIoT) include the optimisation of operational efficiency and cost reduction in production and monitoring equipment and machinery. All kinds of production processes can be better adjusted […]
Finalists announced for Mechanical category in LEAP Awards
Five finalists have been announced for the inaugural Leadership in Engineering Achievement Program (LEAP) Awards’ Mechanical Category. These finalists have created and incredible mix of mechanical component technology advances. The daunting task of judging this highly competitive category went to a panel of independent technical/engineering-oriented judges. Responsible for the Mechanical category were these four judges: Russ […]
Update on flexible-coupling considerations for OEM and plant designs
All couplings transmit torque and angular velocity. Flexible variations compensate for misalignment. Many of the latter even address vibration and improve system dynamics. Design considerations include machine or installation construction and backlash, torsional stiffness, damping, inertia, torque ratings, maximum rpm, size, misalignments, ease of installation, robustness, and cost. For power transmission (as in motors for […]
R+W safety couplings for wastewater applications
R+W has developed a standard model of corrosion proof ball detent safety coupling for clarifier drives in water treatment plants. The industry requires a well sealed, high-grade stainless steel mechanism to stand up to harsh conditions, resulting in the specific design criteria. The function of the ball detent torque limiter is to disengage the driveline […]
