• Shaftless Screw Conveyor Liners Features & Benefits

    A major benefit of shaftless screw conveyors is the elimination of intermediate hanger bearings to support the screw sections. Intermediate hanger bearings are a constant maintenance issue and can be a restriction to bulk material flow. Shaftless screw conveyors rely on trough liners to support the shaftless spiral and provide a bearing surface.

  • Shaftless Screw Conveyors

    The Orthman Shaftless Screw is engineered and designed to convey difficult to move products that would normally be a problem for a typical screw conveyor. This heavy duty screw is manufactured in one continuous helix which rides on the bottom of the housing on a replaceable liner eliminating the need for hanger bearing supports.

    Shaftless screw conveyors rely on trough liners to support the shaftless spiral and provide a bearing surface. Selection of the appropriate liner material and attachment method is critical to ensuring a relatively low maintenance shaftless screw conveyor. utilizes extensive experience and an application database when selecting trough liner

  • Screw Conveyor Trough Liners Manufacturing

    Liner Attachment Methods Several methods are availe for securing screw conveyor trough liners. Engineered plastic liners such as UHMW and Polyurethane are held in place by equally spaced stainless steel blocks or full-length clips bolted intermittently along the top edges of the trough to allow for thermal expansion of liners.

    The trough liner is the spiral’s replaceable bearing surface. The only machined bearings in a shaftless are in the gear reducer. 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 availe in the shaftless design.
