The White Oscillating Ink Form Roller plays a dual role in the SM 74 ink train — as a form roller it contacts the printing plate directly to apply ink, and as an oscillating roller it moves laterally to spread the ink film evenly across the full roller width. This combined function makes the White Oscillating Ink Form Roller critical to both the quality of ink application at the plate and the uniformity of lateral ink distribution throughout the SM 74 ink system.

When the White Oscillating Ink Form Roller wears, hardens, or glazes over time, ink transfer to the plate becomes uneven, leading to low ink density, streaking, ghosting, and inconsistent ink coverage across the press sheet. The oscillating motion is also affected when the roller covering loses its proper surface quality, reducing lateral ink spreading efficiency. Replacing a worn roller with a precision-recovered New Style unit restores both accurate ink application and even lateral distribution on your SM 74.

This is the New Style version, compatible with SM 74 presses from serial number 627,456 and after, and PM 74 presses from serial number PM740 915 and after. Supplied as an exchange unit — return your worn core within 30 days. All exchange rollers are precision-ground and recovered to OEM specifications for a drop-in fit.
