HIGH PRECISION, ZERO BACKLASH, AND TORSIONALLY STIFF: METAL BELLOWS COUPLINGS FROM R+W

High precision bellows couplings are used wherever positional accuracy and dynamic motion are in demand. This can be in medical devices, test stands, wind power turbines, servo axes in machine tools, wood processing machinery, packaging machinery and many more high performance equipment types. As a leading provider, R+W is constantly working to expand its product portfolio of metal bellows couplings for various applications in every size and design.

Bellows couplings are especially suitable for direct connection between two coaxial shafts. The metal bellows defines the characteristics of the coupling and compensates lateral, axial and angular shaft misalignment with low restoring forces. Backlash-free, torsionally rigid metal bellows guarantee precise positioning of the driven load, and can be used in highly dynamic cyclic duty applications, as well as at extremely high rotational speeds - up to 200,000 rpm depending on the model.

In order to be able to take full advantage of the technical properties of the metal bellows, proper installation is critical. Factors such as duty cycle, acceleration torque, inertia and allowable torsional deflection are important factors in the selection process. R+W takes all of these factors into consideration along with general requirements for ease of installation and price efficiency when designing and applying the metal bellows coupling. Thanks to their lack of wear and moving parts R+W bellows couplings succeed in combining economic efficiency with high operational reliability.

R+W provides bellows couplings in a wide variety of designs for projects large and small. Depending on the sizing, bellows couplings guarantee torque transmission ranging from 2 to 10,000 Nm. In addition to its standard product portfolio, R+W offers custom designed solutions for even the most specialized requirements, and is constantly working on further development of its technical expertise.
