Shaftless Screw Conveyors
Since our Shaftless Screw Conveyors do not require a non-drive end bearing this allows for direct connections and optimizes layout design flexibility. End-to-end and side connections not possible on shafted screw conveyors are common solutions available in shaftless design. Vertical shaftless conveyors are available in a single unit up to 50 feet and systems in excess of 100 feet in elevation gain.
The elimination of the shaft and hanger bearings eliminates flow-impediments found in shafted screw conveyors. This also enables a much higher fill rate resulting in slower screw speeds, more efficient conveying and consequently less wear and power usage.
Maximum performance is achieved through zero-clearance between the trough and spiral. It is a space saving, extremely reliable conveying method.
Custom Conveyor Corp’s open shaftless spiral design makes these conveyors ideally suitable to efficiently convey stringy, sticky waste materials that vary in size, volume, capacity or dry solids content. They work extremely clean and efficient for conveying materials such as:

Custom Conveyor Corp. engineers perform important spiral strength calculations on every shaftless application. We utilize many spiral configurations to insure the proper compression or elongation strength is achieved for your application. We manufacture and test all of our conveying products and systems at our 32,000 square foot plant in Rogers, MN to ensure compatibility with and integration into your plant is consistent and flawless.

The World’s Best Spiral Quality = The World’s Best Spiral Warranty
Custom Conveyor Corp’s shaftless spirals utilize European individually hot-rolled, equiaxed grained, high yield strength, high tensile, micro-alloy flat bars (Ni, Cr, Mn) that that are then cold formed into a spiral by our modern “precise captured winding technology” that holds higher diameter and pitch tolerances than any other spiral manufacturer.
