Roll circulation

Challenge

In the automotive industry, machine tools are used in metal-cutting production to machine cast housings. The guiding and setting functions of the tool slide are performed by roller recirculating units (e.g. RUSK). These precision units must be replaced when their target service life has been reached. Since this design is no longer offered as a spare part by original equipment manufacturers, our customer was urgently looking for a suitable alternative.
This multi-part unit, which consists of a roller chain and complex turned and milled parts, is not a typical rolling bearing application. Nevertheless, the Küpper team rose to the challenge and came up with a solution.

 

Küpper solution

By combining our experience in rolling bearing technology with the use of our manufacturing and measuring capabilities, we were able to come up with a solution that not only met the requirements of the specifications, but also took into account the customer's optional requests. Furthermore, the customer was spared the significantly higher costs of converting the existing machinery to the current variant of the reel circulation system available on the market.
