High precision couplings for servo drive technology are what got R+W started 30 years ago on its journey to becoming the world’s leading supplier of zero backlash, low inertia connecting elements. Over this time the product offering has continually expanded to include innovative designs in heavy duty mechanical torque limiters and industrial disc pack couplings, and the most comprehensive offering of bellows and elastomer couplings. Most recently R+W took the gold in the mechanical category of the Leadership in Engineering Achievement Program with its integrated torque and vibration measurement system with wireless signal output, facilitating a more realistic and accessible data set with respect to machine performance and uptime.

Couplings are the perfect place for sensors: A Design World Trends interview
April 3, 2020 2:11pmIn a recent conversation with Andrew Lechner of R+W, we discussed IoT functionality in a new line of couplings from the component manufacturer motion components. Here’s what Lechner had to say. Lechner • R+W: 15 or so years ago, we experimented with bellows couplings capable of measuring misalignment. couplings that can provide information about shaft […]

Flexible disc and bellows couplings from R+W
October 21, 2019 11:39amFor 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 […]

Heavy duty safety couplings from R+W
November 14, 2017 12:56pmR+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 […]
