A bellows couplings from abp is the best choice when it comes to transmitting power backlash-free and angularly synchronized and optimally compensating for misalignment.
We offer you an unusually wide range of products in small sizes from 15 to 40 mm diameter and lengths between 20 and 48 mm directly ex works. Depending on the application, the bellows are made of stainless steel, bronze or nickel, the hubs are made of aluminum and various steel grades. Our bellows couplings are available with screw or clamping hubs.
The miniaturized metal bellows couplings from abp Antriebstechnik are mainly used in rotary encoders, pulse generators, resolvers, slip ring units, servo motors and electric drive components.
A bellows couplings is a flexible shaft coupling. It consists of a metal bellows that connects a driving and a driven shaft. The bellows can be used to compensate for axial, radial and angular misalignments while maintaining high torsional rigidity.
With our 25 years of experience, we at abp Antriebstechnik have built up a great deal of know-how in the field of bellows couplings and their application requirements. Our bellows couplings are therefore ideal for applications that require precise motion transmission with simultaneous compensation capability.
The bellows couplings from abp play a central role in many industrial applications. Its flexibility and precision make it ideal for applications where accuracy and precise compensation of misalignments are essential.

The bellows coupling (also known as a metal bellows coupling or corrugated pipe coupling) belongs to the group of precision mechanical couplings. It consists of a flexible metal bellows and connects two rotating shafts to each other.
The metal bellows ensure that movements or misalignments of the shafts are compensated without any loss of accuracy or torsional rigidity. In this way, the bellows coupling enables backlash-free torque transmission while simultaneously compensating for axial, radial and angular displacements.
You can find out exactly how the bellows coupling works here.
Thanks to its flexible design, the bellows coupling is ideal for precise applications where maximum accuracy is required. This makes it particularly suitable for applications such as servo drives, measuring systems, machine tools and robotic drives.
A bellows coupling transmits torque between two shafts via its flexible metal bellows. It connects both shafts and enables precise and even torque transmission without delays or movement distortions.
Thanks to its flexibility, the metal bellows can compensate for mechanical irregularities, such as axial, radial and angular shaft misalignments. This reduces mechanical wear and significantly increases the service life of the connected components.
An outstanding feature of bellows couplings is their high torsional rigidity. It enables precise rotary movements to be transmitted without twisting in the bellows, even at high torques. This is particularly important for dynamic applications such as fast movements or load changes.
While the metal bellow can absorb minor vibrations, its main advantage lies in the precise and backlash-free transmission of forces. This makes bellows couplings ideal for applications that require high accuracy and reliability, such as in automation technology or servo drives.
A bellows coupling offers a number of advantages that make it ideal for applications with high precision, zero backlash and flexibility requirements.
The bore describes the inner diameter of the coupling hub, which must fit exactly onto the shaft on which the coupling is mounted. Each bellows coupling consists of two hubs and the metal bellows between them, which transmits torque and compensates for misalignment. The bore dimensions are crucial to ensure that the shaft connection functions without play, safely and precisely.
At abp, we specify the bore holes for our metal bellows couplings in a table with d1/d2 (e.g. 6/8 mm) on the respective product subpages. These values represent the inner diameter of the respective hub on the drive and output sides.
The technical data sheets and illustrations for each product also list all relevant tolerances, torques, torsional stiffness and maximum speeds. This makes it easy to check whether the selected coupling meets the mechanical requirements.
If you are still unsure, our service team will be happy to provide you with comprehensive advice and further information.
The clamping hub is a precise and service-friendly fastening technology. It encloses the shaft in a form-fitting manner and is fixed in place using one or more clamping screws. This variant offers:
The clamping hub design is particularly recommended for applications involving frequent shaft changes or precise adjustment (e.g. servo drives, measuring systems, machine tools). It enables precise positioning of the shaft without tilting and ensures even force distribution over the entire circumference.
The bellows couplings from abp are used in numerous industries as they enable the precise and backlash-free transmission of torque as well as the compensation of shaft misalignments. Some examples are:
The range of applications for our bellows couplings is as wide as our product portfolio. They are primarily used where high precision and zero backlash are required.
Some examples of applications for our bellows couplings are:
In many applications, control and regulation circuits rely on highly accurate positioning and position feedback. Rotary encoders or resolvers must be connected to the drive in a torsionally rigid and flexurally flexible manner.
We at abp are well aware of this. Over the past 25 years, we have built up extensive know-how and a high level of expertise in the field of bellows couplings. As a result, our metal bellows couplings have very high torsional rigidity with low restoring forces and transmit rotational movements to the sensor without error. In addition, the vibration-damping effect of the bellows minimises the bearing load on the shafts.
At abp, we specialise in small and medium series production. This enables us to respond very precisely to customer-specific requirements. As a bellows coupling manufacturer, we also manufacture all products in-house at our site in St. Georgen in the Black Forest (Germany), which means we can guarantee fast delivery times.

A bellows coupling from abp is always made of high-quality materials such as stainless steel or anodised aluminium. These materials ensure a long service life, corrosion resistance and the ability to function reliably even under difficult conditions.
However, the material used for the bellows coupling depends heavily on its area of application. That is why we at abp work closely with our customers in a spirit of partnership. Together, we will find the ideal bellows coupling for your requirements. Feel free to contact us!

There are numerous factors to consider when manufacturing bellows couplings. At abp, we have acquired a high level of expertise in the manufacture of bellows couplings over the last 25 years. In order to manufacture a precise and durable bellows couplings, the following aspects in particular must be taken into account:
Although metal bellows couplings are essentially maintenance-free and durable, their service life can be significantly extended by taking specific measures to ensure that the entire drive system remains fault-free.
