Shaftless Spirals and Liners
Claro shaftless spiral screws and trough liners are backed by over 25 years of research and applications experience. Whether for a new system or for a spare parts retrofit, Claro provides spiral configurations that maximize conveyor system performance and spiral life. Let us improve the performance of your current shaftless or shafted auger conveyor system.
Claro supplies both shaftless and shafted augers, however, for a description of why well-engineered shaftless spiral conveyor systems are often a better technology choice over other approaches, please see Claro Conveyors.
