Shaft Collars

Adjusting Rings

Special Turned Parts


Your reliable partner for clamping rings & turned parts

We are a medium-sized family business with a focus on the production of shaft collars. In addition, we offer our customers the manufacturing and sale of adjusting rings and high-quality turned parts.

Many well-known companies from the fields of materials handling technology, mechanical and plant engineering, medical technology and drive systems, which have high demands on quality and reliability, place their trust in us.

We, of course, want to live up to this claim, which is why we pay attention to the highest level of care in all production areas. Our motivation is your satisfaction. Open communication is very important to us.

We strive to maintain a reliable, competent and trustworthy partnership with our customers.

A well-trained, motivated and reliable team is at your side.

Safe on the shaft...

...from micro to heavy duty applications

Shaft collars are components in drive technology. Due to their countless application possibilities, they can be found in almost every system. They are used to fix components or stop surfaces.

We are the leading manufacturer of shaft collars on the German market. We produce one-piece and two-piece shaft collars. The popular two-piece version offers quick installation and removal, especially in inaccessible areas. Shaft collars provide an even distribution of retention forces and do not damage the shaft.

As a manufacturer, we offer you a wide range of dimensions and finished shaft collars for shaft diameters from 5 to 200 mm!

In order to meet your short-term requirements, we have shaft collars made of free-cutting steel and 1.4305 materials in standard dimensions ex stock.

Special dimensions and materials are no problem for us. We are happy to take on the challenge with special requests regarding clamping rings and to implement your individual shaft collar project with you.

Common surface treatments, from burnishing to galvanising, are a matter of course for us.

Our clamping ring stock includes threaded clamping rings, double shaft collars and heavy duty shaft collars.

A selection of our standard shaft collars dimensions can be found on - the new marketplace for new and used machines,service, tools and spare parts.


Easy attachment!

Simple and effective. Set collars are still the most requested machine part when it comes to shaft mounting. They are an indispensable element in securing mechanical stops. The retaining force of the shaft collars is ensured selectively via the threaded pin, which fixes it on the shaft. The shaft collar is usually manufactured according to DIN705.

For our set collars, we offer for the standard DIN 705, as well as for our shaft collars bores for shaft diameters from 5 to 200 mm!

Of course, we also have standard adjusting ring dimensions according to DIN 705 made of free-cutting steel and 1.4305 in stock.

Of course, we also offer you the possibility of manufacturing special dimensions in all common machinable materials for our set collars.

Rigid shaft couplings - A good connection...

As a supplement to our clamping and adjusting ring range, we offer you rigid shaft couplings for shaft diameters up to 35 mm and maximum lengths of 70 mm. Rigid shaft couplings provide simple and safe installation. They are used for simple drives and can be used at high torques and speeds. They are not subject to wear, are maintenance-free and can be used independently of the rotation direction. Rigid shaft couplings provide a force-locking connection. Rigid shaft couplings are available in slotted and fully split versions. A keyway, as well as different shaft diameters are available on request.

Rigid shaft couplings are available from us in free cutting steel and 1.4305. As with our adjusting rings and shaft collars, we offer rigid shaft couplings with all common surface treatments.

Miniature couplings & collets

Depending on the application, the miniature couplings, which are made of one piece, are equipped with simple and multiple spiral incisions. This allows for high torsional stiffness and effective reduction of windup effects. Angular misalignments, axial displacements and radial relocations are also effectively compensated. The couplings are used for general positioning requirements with low torques and load torques due to their reaction forces in metrology and the acceptable torsional stiffness values in linear technology. Miniature couplings also serve as connecting elements between highly dynamic servo motors. They are characterised by simple assembly and disassembly, and thanks to their compact design can be used in almost every application.
