Accessories
Manganese Wear Rails
Specifically designed for the use with drop forged, heat-treated chain links, 4B Manganese Steel Wear Rails provide a low friction, highly wear-resistant ‘running surface’ for conveyor drag chains.
They extend the life of chain conveyor casing bottom plates (and other areas, depending on machine design, handled material and application), protecting against costly wear and premature casing panel replacement.
