Ruland Manufacturing has expanded its line of bellows couplings to include an outer diameter of 2-1/4-in. (57 mm), allowing for larger bore sizes and increased torque and torsional stiffness capabilities. Designers prefer to specify bellows couplings in servo-driven systems due to their high accuracy and repeatability. This size expansion now allows for bore sizes up […]

Ruland aluminum MBCK33-14-8-A bellows coupling
Ruland MBCK33-14-8-A is a clamp bellows coupling with 14mm x 8mm bores, 33.3mm OD, 42.9mm length, and 5mm x 2mm keyways. It is zero-backlash and has a balanced design for reduced vibration at high speeds. MBCK33-14-8-A is comprised of two anodized aluminum hubs and a stainless steel bellows. The bellows are able to flex while […]
Ringfeder couplings for advanced motion control
Check out Ringfeder’s latest video to learn more about its best-of-class coupling solutions for advanced motion control applications, including surgical robots, semiconductor equipment, lab automation, and industrial robots. Used in high-accuracy applications, our elastomer jaw couplings dampen vibration and compensate for radial, axial and angular misalignment. Another option is the company’s metal bellows couplings, which […]
Ringfeder couplings for advanced motion control systems
Users already know the important role Ringfeder couplings play in heavy-duty equipment, from cranes and hoists to pumps and compressors. But coupling can also make or break applications requiring advanced, precision motion control — like surgical robots, medical device manufacturing, medical imaging, lab automation, semiconductor equipment, and industrial robots. A Rundown of Ringfeder Couplings When […]
The eight best ways to wreck your coupling driven system
Keeping a servo-driven system running at peak efficiency is no simple feat. Misunderstanding performance criteria such as misalignment, torque, or RPM can be all it takes to cause a critical failure. The following are the eight best ways to consistently sabotage or damage your coupling driven system (and how to avoid them in the future). […]
Altra brakes, clutches, limit switches, and couplings on stage scenery winches
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 […]
