Small Diameter Shaft – Air

Convertech’s Small Diameter Air Shafts are true to their name. This type of air shaft is among the smallest diameter shafts available and are the perfect instrument to be used for narrow and wide web application. Convertech offers Small Diameter Air Shafts in both the leaf and lug styles.

Small Diameter Air Shaft Features

Small Diameter Air Shafts are built to fit your needs and unique applications. With diameters starting at 0.4” and face lengths up to 150”, there are a wide array of options to cater to your needs and requirements.

Our lug style Small Diameter Air Shafts house multiple lugs that expand equally around the inside the core. Our leaf style Small Diameter Shafts operate in a similar way, however, they feature the advanced integration of high-quality materials that are not found in the lug style shafts. They contain anodized aluminum which expands uniformly along the entire length of the shaft. Both styles are specifically designed to provide a precise grip when winding and unwinding.

Our Small Diameter Air Shafts are custom designed to fit your unique needs and specifications. When placing an order for Small Diameter Air Shaft, customers are asked to specify whether they need a quote for the flanged, double journal, or cantilevered version to ensure your Small Diameter Shaft fits your needs and specifications.
