Heidelberg SM 74 Yellow Oscillating Ink Form Roller (Exchange)

The Heidelberg SM 74 Yellow Oscillating Ink Form Roller is a precision-recovered exchange roller designed specifically for the Heidelberg SM 74 offset printing press. Part number M2.009.631F, this oscillating ink form roller is supplied one per unit. As both a form roller and an oscillator, it simultaneously applies ink to the printing plate surface and moves laterally to distribute ink evenly, making it one of the most critical rollers in the SM 74 ink train for consistent ink coverage and sharp dot reproduction.

A properly functioning Yellow Oscillating Ink Form Roller is essential for uniform ink density, clean halftone dots, and stable color throughout the press run. When oscillating form rollers wear, harden, or develop glazing, ink delivery to the plate becomes uneven, resulting in streaking, ghosting, ink stripes, and inconsistent ink density. The oscillating action also diminishes over time, reducing lateral ink distribution and amplifying ink train imbalances. Replacing a worn oscillating form roller with a precision-recovered unit restores both ink application and lateral distribution, improving overall print quality and reducing makeready waste.

This Heidelberg SM 74 Yellow Oscillating Ink Form Roller is supplied as an exchange unit. Return your worn core within 30 days to avoid additional charges. All exchange rollers are precision-ground and recovered to OEM specifications, ensuring a drop-in fit on your Heidelberg SM 74 with no press modification required.
