We only develop products which are adapted and developed to your application. We do not make bearings or products which can be found in the catalog. The use of standard bearings is a pure fight for price that we do not go along with.
Rollax gives you gain in your development, new functions with better package and - above all - you save money. Our bearings can save costs in your processes. For example, we compensate your tolerances so that you do not need to grind anymore.
Two things are necessary for this:
A) Number of pieces> 50,000 pieces / year
B) We advise you in the surrounding of the bearing. We have to see what exactly is the purpose of the bearing in your application.

In the year 1949, Paul Hedfeld established a business for the production from machines to the grain and flour-conveying as well as for the construction of wear parts for mills and compound feed plants. Today, the business chain- and belt- elevators, screw conveyors, troughchainconveyors and all the spare parts you need for them for all industry-branches also beyond the borders of Germany and Europe. Planning and construction come after the customer's individual wishes and for are fitted the local realities.
