The backlash-free, flexible ROBA®-ES elastomer couplings by mayr® power transmission compensate for radial, axial and angular shaft misalignment. They protect the drive system against critical vibrations.




mayr® power transmissionmayr® power transmission provides a wide spectrum of backlash-free, high-performance servo couplings and is permanently expanding its standard modular system. Furthermore, new, modern production processes ensure favourable prices and short delivery times. In addition, the company also stands for diverse, future-orientated solutions for safety brakes and overload clutches. For customers, this means high-quality power transmission from a single source.


Shaft couplings in servo axes are subjected to completely different requirements depending on the application.
For this reason, mayr® power transmission provides an extremely wide and mature product portfolio, featuring various steel bellows, elastomer and disk pack couplings in their product range. Just recently, the company extended its standard modular system with several new hub designs and intermediate sleeves. “With our wide variety of versions, we create a high degree of flexibility for various applications”, explains Ralf Epple, Product Manager at mayr® power transmission. “We are therefore in a position today to provide solutions for all drive constellations in servo technology easily and quickly”. The intelligent modular system also ensures high availability and short delivery times for standard components. Furthermore, mayr® power transmission is equipping itself for the future and is reacting to continuously increasing challenges with new, modern production methods and optimised internal handling. “For our customers, this means a large selection of servo couplings, short delivery times and favourable prices – naturally in the accustomed quality, made by mayr® power transmission in Mauerstetten”, concludes Ralf Epple.


Know-how and equipment

mayr® is one of the worldwide leading companies in mechanical power transmission and can – in particular when dealing with difficult application cases – call on appropriate know-how and decades of experience. As a result, the company also has, for example, high-speed servo couplings with speeds up to well over 20,000 rpm in its product range. On these constructional designs, the individual parts are manufactured to high accuracy and constrained radial run-out tolerance and axial run-out deviation, and are balanced in completely assembled condition. Due to the fact that these couplings – as with all other constructional designs – must be accurate and function reliably, mayr® power transmission extensively tests all couplings on modern test stands under the conditions which also prevail in real applications. As a result, the consistently high quality of the products is guaranteed.
Although shaft couplings are frequently categorised as a simple accessory part, they are nevertheless important components in the overall system. Should questions regarding these products arise, or should advice be required or necessary, mayr® power transmission is available to customers with technically competent contact partners – not only in Germany, but also through a global Service network.


Complete solutions from a single source

In addition to shaft couplings, mayr® power transmission has developed and produced ground-breaking, reliable safety brakes and overload clutches for decades. “Our customers appreciate receiving everything from a single source and therefore if possible saving on additional suppliers and costs”, adds Ralf Epple. Therefore, in many applications, for example, combinations of shaft couplings and torque-limiting safety clutches are used. The latter protect machines against expensive overload damage. mayr® power transmission provides the know-how and service from a single source for these complete solutions.
