HIGHLIGHTS



MDR's have become one of the most widely used types of conveyors today, thanks to their efficient design. 24Volt DC Motor driven rollers utilize motorized zones, in which a motor drives each zone or multiple rollers drive longer zones. Programmable MDR drive cards are provided which enables conveyors to provide zero pressure accumulation along with variable speed options - Programmable MDR drive card EtherNet/IP compatible. MDRs are provided for ambient temperatures and can be provided with various coatings on rollers.

MDRs are offered in chain driven live roller (CDLR) - Belt Driven Live Rollers (POLY "V") for high speed applications - Line Shaft type conveyors using "O" rings to drive the conveyor - MDRs are also used for driving chain conveyors and air operated pop up chain transfers built integral to roller conveyors.
