Custom Rubber Rollers for Heidelberg SM74 CD74
Product Overview:
AstraRoll manufactures direct-fit replacement rubber rollers for Heidelberg Speedmaster SM74 and CD74 offset presses. Covering the full spectrum of ink form, oscillating distributor, ductor, and dampening positions, our rollers are CNC ground to ensure uniform nip pressure across the entire face width.
Each roller features precision-machined metal journals and positional end markings, allowing press operators to identify and install the correct roller without cross-referencing part numbers. Compound hardness is strictly matched to the application: 30–35 Shore A for conventional inks, 35–50 Shore A for UV inks, and 25–28 Shore A for dampening rollers. Available in standard NBR, with EPDM or Silicone options on request.

Custom Rubber Rollers for Heidelberg SM74 CD74 Details
Product Overview
AstraRoll’s Custom Rubber Rollers are engineered as direct-fit replacements compatible with the inking and dampening units of Heidelberg Speedmaster SM74 and CD74 sheetfed offset presses. Replacing worn, glazed, or swollen rollers is critical for maintaining consistent ink film thickness and preventing print defects.
To eliminate maintenance errors, our rollers are fitted with precision-machined metal shafts and positional end markings. This allows operators to visually identify the correct roller for each specific position on the press. All dimensions are strictly matched to original specifications for a true drop-in fit, with custom shaft ends and core configurations available upon request.
