PCI FC and MC Series drum pulleys are used in numerous locations within a conveyor system such as head positions to drive a belt, or in return/tail, snub, bend and take-up orientations when belt tension and redirection is needed. Each series provide numerous choices for hassle-free selection in most standard to medium duty drum pulley applications. The main difference between these two products is the method used to crown the pulley face when a crown profile is specified. FC Series pulleys receive a crown that is formed into the face of the pulley while MC Series pulleys utilize machining operations to accomplish the crowned profile. Because MC Series pulleys require machining, they are typically constructed from thicker materials as well. Both FC and MC Series pulleys ordered with vulcanized lagging would receive a crown machined into the lagging versus a crown provided in the core.
