Maintain the structural integrity of your machine with the Heidelberg Washer (Part No. C4.721.060/04). While often overlooked, washers in this category are critical for maintaining the specific torque requirements of assembly bolts within the press frame, gripper shafts, and delivery units.
Technical Specifications:
-
Part Number: C4.721.060/04
-
Alternative Codes: C4.721.060, C472106004
-
Material: High-tensile hardened steel with a corrosion-resistant coating (Zinc-plated or Black Oxide finish).
-
Type: Flat Precision Washer / Spacer.
-
Dimensions: Specifically calibrated to match the diameter and thickness requirements of C-series mechanical sub-assemblies in Heidelberg machines.
Compatibility: This part is widely utilized across the Heidelberg product line, appearing in various mechanical assemblies for:
-
Speedmaster: SM 52, SM 74, SM 102.
-
CD Series: CD 74, CD 102.
-
Applications: Commonly found in the dampening unit, feeder timing mechanisms, and drive-side protective covers where precise spacing and fastening are required.
Key Features:
-
Vibration Resistance: Designed to withstand the harmonic frequencies of presses running at 15,000+ sheets per hour.
-
Corrosion Protection: Treated to resist the moisture and chemical exposure typical of a pressroom environment (inks, solvents, and fountain solutions).
-
OEM Standard: Guarantees a perfect fit and consistent hardness level, preventing the “softening” or deformation common in generic hardware.
Prevent mechanical fatigue and ensure your press remains securely assembled. Use only genuine Heidelberg hardware like the C4.721.060/04 from Equigraf.
