Heidelberg SM 74 Ink Ductor Roller (Exchange) M2.009.261F

The Heidelberg SM 74 Ink Ductor Roller is a precision-recovered exchange roller that meters ink from the ink fountain roller into the roller train on the Heidelberg SM 74 offset printing press. Part number M2.009.261F, the ink ductor operates on a timed, intermittent contact cycle — swinging between the ink fountain roller and the first distribution roller to pick up a controlled film of ink and transfer it into the ink train on each stroke. This metered, intermittent transfer is the critical first step in the SM 74 ink supply chain, and the condition of the ductor roller directly determines how consistently ink is delivered to the roller train on every impression.

A worn or glazed SM 74 Ink Ductor Roller causes erratic ink metering, resulting in ink density fluctuations, ghosting, and difficulty maintaining stable ink levels during long press runs. The ductor’s rubber covering undergoes thousands of intermittent contact cycles per hour, making it one of the faster-wearing components in the SM 74 ink train. Hardening or glazing of the covering reduces ink pickup efficiency and introduces variability into ink supply that cannot be corrected through ink key or ductor timing adjustments alone. Replacing a worn M2.009.261F with a precision-recovered exchange unit restores accurate, consistent ink metering and stabilizes ink density across the run.
