Custom Heidelberg SM74 Printing Rubber Roller

Product Overview

AstraRoll‘s Custom SM74 Intermediate Roller is engineered for the Z roller (bridge roller) or specific form roller positions in the Heidelberg Speedmaster SM74 inking/dampening system. In operation, this roller transfers a controlled ink film to stabilize ink-water emulsification.

The defining feature of this roller is its integrated threaded adjustment arm assembly at both ends. Unlike standard rollers with fixed journals, the threaded spindles and lock nuts allow maintenance technicians to precisely dial in the contact pressure against adjacent rollers—a critical setting for consistent ink film splitting and avoiding roller bounce or stripe marks.

The roller body is available in Rilsan (Polyamide/Nylon) for high solvent resistance, or High-Hardness Rubber (NBR/EPDM) to match the exact tactile requirement of your press. The precision steel core and custom-machined spindles ensure reliable, long-term operation.

Application

Heidelberg SM74 / PM74 Presses: Replacement for worn or damaged intermediate/transfer rollers with adjustment mechanisms.

Inking–Dampening Bridge: Transfers ink film to the dampening form roller for stable emulsion control.

Nip Pressure Adjustment: Threaded arms allow precise setting of contact pressure, reducing bounce and print defects.
