Didde Web Press Roller 329-708

The Didde Web Press Roller 329-708 is a precision-recovered Distributor roller designed for use on the Didde 860 and Didde Model 20.5″ web offset printing presses. Part number 329-708, this roller also matches Lith-O-Roll part number DG-329-03-B. The distributor roller plays a central role in the ink train by oscillating laterally to spread and level the ink film across its full width, working in combination with form rollers to deliver a smooth, even ink film to the printing plate. Consistent oscillation and a sound roller surface are essential for uniform ink density and clean print reproduction across the web.

When a distributor roller on a Didde 860 or 20.5″ becomes worn, glazed, or loses its oscillation efficiency, the ink film develops uneven lateral distribution — resulting in ink stripes, ghosting, and density variation from one side of the web to the other. These defects are often difficult to correct with ink key adjustments alone because the problem is mechanical, not a settings issue. Replacing the worn 329-708 with a precision-recovered distributor restores proper lateral ink spreading and eliminates distribution-related print defects.

Please verify the part number prior to ordering — many Didde models share rollers that may be interchangeable across configurations, and confirming the correct part number ensures you receive the right distributor roller for your specific press.
