Screw Conveyors
Add on to an existing screw conveyor or keep it running like new.
Screws are designed for right-hand operation. Screws with a thicker edge offer longer service life for abrasive materials.
Discharge spouts can be welded to a cutout in the trough.
Coupling shafts connect two screws together. End shafts support the end conveyor section. Coupling bolts connect shafts to the screw.
End-shaft seals prevent material contamination and discharge.
End-shaft bearings support the end of the shaft and help the screw rotate.
Bearing hangers mount inside the trough.
Hardwood bearings are oil impregnated and are often used in agricultural applications. UHMW bearings work well with chemicals and wet environments. Iron bearings are oil impregnated and offer longer life for abrasive materials. Bronze bearings are oil impregnated.

Thread-Mount Bearings
Combine with threaded pipe to mount these bearings in a variety of positions without the need for a flat mounting surface. Bearings are self-aligning to compensate for shaft misalignment. Seals block out dust and contaminants.
NPSM (National Pipe Straight Mechanical) threads are compatible with NPT threads. See more about pipe thread type and sizing.
