Through Shaft – Air

The Convertech Through Shaft are uniquely suited for wide web core applications and is compatible with all chuck diameters and shaft adapters. These shafts provide a lightweight alternative to a bulky and heavy shaft that runs larger diameter cores.


The Through Shaft can be made with a steel or aluminum body. It can be designed with a diameter from 5” to 16” and face length up to 150”. All chuck diameters can be mounted on the shaft and the lighter weight makes the through shaft well suited for large diameter cores.


Our Through Shafts are custom designed to fit your specifications. When placing an order for Through Shaft, we ask that you specify whether you need a quote for the double journal version so that we can make sure your Through Shaft fits your needs and specifications.

As with all of our shafts, we guarantee that your Through Shaft will be designed and manufactured to the same tolerances as all of our industry’s leading shafts.


Please contact us for a more specific lead time, to request a quote, or if you have other questions.
