Our Products

Bearing Tubes

Our decades of experience and state-of-the-art manufacturing processes ensure high quality products. Our traditional bearing tubes and cuts include a range of options: hot-rolled, cold-rolled and cold-drawn tubes. Optional finishes include peeling and cold pilgering. Available in a nearly gapless range. Our exclusive cold-rolling technique lessens eccentricity and increases tolerances for optimized machining.


An outstanding alternative to turned rings, Smartubes are designed to offer a simple and competitive tube for bearing components. These cost-effective tubes adapt to our customers’ manufacturing equipment. Smartubes are hot-rolled at our Mülheim mill and finished and heat treated at our Montbard facility.

We offer a full-service solution: our supply chain can be adapted to your specific project needs, from the size of your order to logistics solutions.
