BC Caire, a leading French manufacturer of stage equipment needed reliable and quiet powertrain components for use on new scenery winches at the Théâtre du Chatelet in Paris. The 2500-seat theater has undergone many restorations and upgrades since its original construction in 1862. In mid-2019 the theater re-opened after a major 2-1/2 year, 31 M€ […]

Flexible disc and bellows couplings from R+W
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 […]
Servometer SMC 300 Series bellows coupling
Precision bellows couplings are characterized by diameter and the number and spacing of the convolutions. The convolutions allow for a highly flexible, yet rotationally rigid coupling. Electrodeposited nickel bellows have a precisely controlled wall thickness that gives it a combination of sensitivity and high torsional stiffness for precise rotational adjustment and positioning. The SMC 300 series […]
Flexible shaft couplings from Servometer
As a provider of extremely flexible and highly dependable bellows and beam couplings, Servometer offers a wide choice between standard parts for replacement, testing, and development, or a custom bellows design for peak efficiency and reliable 24/7 operation even in extreme environments. Matching your application requirements with the right coupling depends upon the coupling design. […]
Types of metal bellows from MW Industries
Edited by Mike Santora Hydroformed Metal Bellows Formed bellows are produced two ways; hydro-forming & mechanical forming. Both are produced by reworking tubes into convoluted bellows. Hydro-formed bellows will use a die and high pressure fluid to form the convolutions. Mechanically formed bellows will use a die and a roller to cold work the convolute […]
R+W for continuous use conveyor applications
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 […]
How do I evaluate shaft misalignment?
To gain some insight on evaluating and understanding shaft misalignment, we talked to Bobby Watkins of Ruland manufacturing company to learn more. Here is what he had to say. Here is just a quick tip for evaluating shaft misalignment. On some couplings, a good scale or straight edge is good enough to run it across […]
Do bellows couplings require precision alignment?
Bellows couplings are an excellent choice when selected for the proper application. We asked Bobby Watkins of Ruland Manufacturing to give us some insight on proper coupling selection. The following is an excerpt from the bellows coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. Bellows couplings are for precise […]
Standard line of atherm bellows
Servometer has expanded their bellows assembly product line based on their proven Athermilization Bellows technnology which provides linear movement in response to changes in temperature. Advantages: • Precise temperature-dependent mechanical actuation without the need for programming or electricity. • Mechanically modulate heating and cooling systems. • Operate through billions of repeatable cycles without drawing power […]
SP3 metal bellows coupling with external clamping ring
The range of SP3 metal bellows couplings has been expanded to include new models. The welded design is capable of transferring torques of between 800 and 10,000 Nm. Previous models of the SP3 with external clamping ring were available for torques of between 60 and 500 Nm. The coupling can be installed via the external […]
