PROBLEM

Our customer operates several old Medart straighteners which include fairly large custom fabricated universal assemblies. Over the years, the price and availability of parts for these custom assemblies had gotten worse and worse.

SOLUTION

We did a careful review of the application with our customer. A preliminary review showed that we could supply a replacement of current design. In detailing a final selection, our customer asked if we could come up with a single shaft to replace the two different lengths currently in operation. Closer examination revealed that they were absorbing axial slip for roll movement in their gear box. We discussed using a mid-slip universal shaft for this purpose. On a subsequent visit, we took careful axial measurements and determined both installations could be met if the gear boxes could be fixed in specific positions. The result is one shaft for both locations. Additionally, the new assembly is a superior design with reasonable price and availability. This upgrade will result in less down time and lower maintenance costs.
