The existing Ajax gear coupling could not cope with the misalignment required for this pickling line drive. The lubricant leaks out because of grease seal wear causing the coupling to fail. Because there are a number of couplings involved, this problem generated significant down time and required a sizable investment in spare parts.


After a careful review of the application, we suggested a custom universal joint assembly that we could build to fit their floating shaft requirement. They liked the idea and were anxious to make the change, but were disappointed that their coupling stock would be obsoleted. It turns out that we were able to make up the universal shafts with special end plates that would drop right in with no modifications allowing them to use their old inventory.

This design has been running for several years and all of the gear couplings have been replaced. Let us know if you need a custom assembly for an upgrade.
