Didde Web Press Roller 329-702

The Didde Web Press Roller 329-702 is a precision-recovered Hard Distributor roller designed for use on the Didde 860 and Didde Model 20.5″ web offset printing presses. Part number 329-702, this roller also matches Lith-O-Roll part number DG-329-03-A. As a hard distributor in the ink train, the 329-702 oscillates laterally to spread and homogenize the ink film across the full width of the roller train — a function critical to eliminating ink stripes, ghosting, and uneven ink density on Didde web presses. Hard distributors work in combination with rubber form rollers to ensure a smooth, uniform ink film is presented to the printing plate with every impression.

When a hard distributor roller becomes worn, out-of-round, or develops surface defects, the oscillating distribution function is compromised, leading to uneven lateral ink spreading, striping across the web, and inconsistent print density from edge to edge. Replacing the worn 329-702 with a precision-recovered unit restores correct oscillation performance and uniform ink distribution, helping your Didde 860 or 20.5″ produce consistent, high-quality print output with minimal makeready waste.

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 roller for your specific press.
