“From needle bearings in electric motors to roller bearings in offshore wind farms - Supfina develops and produces solutions for the precise machining of rings and rolling elements.“

The challenges facing the roller bearing industry are as great as the diversity of its products: Between deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, tapered roller bearings and spherical roller bearings - an almost infinite number of shapes and dimensions are used. Supfina always has a suitable solution for your perfect shape and surface.

In this way, our machines and plants meet and exceed the requirements of our customers in terms of economy, flexibility and quality. Our continuous development work in close cooperation with the roller bearing industry stands for our customer-oriented approach and makes Supfina technology lean and future-proof.

Modular System

As a system supplier for superfinishing, double-disk grinding, fine grinding and plane finish machining, we offer you individual complete solutions for the precise fine machining of surfaces in the micrometer range.

Perfectly coordinated automation and the right system peripherals, when combined with our modular systems, create solutions for every area of application.

Make Your Production Smart

Have you considered… Increasing added value through integrated sensors and smart data analysis? Incorporating intelligent production through networking with the strategic communication of the entire operation? Increasing profitability by optimizing ordering processes, material flows and production? Improving Overall Equipment Effectiveness (OEE) through better planning of service and maintenance work?

If so, we will be happy to support you in this with our SQS products along with the experience we have accrued over many years in a plethora of different areas.

Protect Resources

Surfaces that are precisely optimized to meet our stringent requirements ensure reduced friction, lower noise emissions and a considerably longer service life. These factors protect resources and are an important component for environmentally friendly energy generation and use. With our decades of experience, we will support you in component design, the appropriate process technology and product development.


Reduction of ripple and therefore less noise and vibration

Improved roundness for higher speeds and accuracies

Improvement of the contact ratio and thus higher load carrying capacity of the bearing
