EMT's Lightweight Pneumatic Multi-Bladder Series Shaft has a light weight aluminum extruded body and is e
quipped with multiple gripping lugs positioned symmetrically around the shaft body. Each lug has an expandable bladder underneath it. When the bladders are inflated, the lugs extend out of the shaft body and grip the core. The lugs run the length of the shaft body making this shaft ideal for narrow or multiple narrow rolls. As an option, the shaft can be equipped with a rotating union for continuous air supply. Each shaft is custom made to your specific requirements.
