Complete production to benefit the customer

Modern and powerful machine shop

In addition to experience, our great strength lies in our ability to completely manufacture all of the drive components. In conjunction with our foundry, we manufacture our drive units on the most modern CNC machines. Vertical lathes up to Ø2,500 mm and high-performance machining centers are the basis for fast and high-performance machining.

We also offer all of our services for high-performance machining as a sub contract service. In this way, we try to ensure constant machine utilization and offer our customers further added value in the joint partnership.

Surface treatment and finishing

Due to the increasing demands of our customers, we have also invested further in finishing and additional services.

Standard paint, special paint or specific surface passivation

Depending upon the customer requirements, our drive pulleys can be supplied primed or completely painted/surface treated. The aim is to best meet the requirements of our customers according to project cost criteria

Rubber coating for transport or elevator drives

With all of our experience, we ensure the ideal rubber coating of the drive pulleys. Depending upon the application, food-safe or heavy-duty rubber layers are also possible. We are happy to support and advise you with our many years of experience.

Sub contract balancing

All drives are balanced on our modern balancing systems according to DIN 21940. After consultation with our customers, we ensure that the drive elements are balanced with great precision in order to ensure we achieve the best low-vibration power transmission during operation. Sub contract balancing is also carried out daily for our customers as a service, and many of our own production parts are provided to us for balancing.

Drive design - your optimised drive

The great advantage of the drives is the totally performance-oriented dimensioning. We calculate your drive according to your performance parameters and ensure the ideal efficiency.

A change or modification in the geometry is always possible with little effort and WITHOUT model costs.

The details of the specific drive design are also used for performance optimization. We have various software systems at our disposal so that our team of engineers and technicians can design your drive according to your requirements. We support you on site and also advise you on the selection of the right drive belt.
