35x7x1.2mm White Rubber Sucker For Offset Machinery Printing

35x7x1.2mm White Rubber Sucker For Offset Machinery Printing is a premium-grade replacement component engineered specifically for high-speed paper handling and feeding systems in the printing industry. This durable suction cup utilizes high-quality white rubber to ensure a non-marking, firm grip on various paper weights and textures. Furthermore, its precise 1.2mm thickness provides the ideal balance of flexibility and structural integrity required for rapid vacuum cycles. Consequently, integrating these suckers into your press machinery minimizes paper jams and double-sheet feeding errors. Therefore, maintenance professionals should stock these essential consumables to maintain peak operational efficiency and superior print registration during long production runs.

Key Features:

• Non-Marking Material: The high-purity white rubber composition prevents ink smearing and physical marking on delicate or high-gloss paper stocks.
• High Resilience: This component exhibits excellent elastic recovery, allowing it to maintain its shape and suction strength even after millions of mechanical cycles.
• Optimal Suction Flow: The 7mm inner diameter facilitates a rapid vacuum buildup, ensuring the feeder head picks up sheets with consistent timing.
• Chemical Resistance: The specialized rubber compound resists degradation from common printing chemicals, fountain solutions, and ozone.
• Precision Fit: Manufactured to strict industrial tolerances, these suckers fit perfectly onto standard 7mm nozzles found in major offset printing brands.

• Temperature Tolerance: −10°C to +70°C
• Surface Finish: Smooth, non-porous grip surface

Mechanical Specifications:

• Attachment Type: Slip-on Friction Fit
• Elasticity: High elongation at break to accommodate irregular paper surfaces.
• Suction Type: Flat-face suction for smooth sheet separation.
• Wear Resistance: Designed for high-frequency vibration and repetitive vacuum stress.

Dimensions:

• Overall Diameter: 35.0 mm (±0.2 mm)
• Mounting Hole: 7.0 mm (±0.1 mm)
• Sectional Thickness: 1.2 mm
• Weight: ≈ 1.5 g per unit

Pinout and Wiring:

• Installation Method: This is a mechanical part; however, it requires a secure press-fit onto the vacuum nozzle of the feeder assembly.
• Vacuum Connection: Ensure the suction nozzle is free of debris to prevent air leaks and maintain maximum lifting force.
• Alignment: Align the sucker flat against the paper path to ensure even pressure distribution during the pick-up cycle.

Commonly Used in:

• Heidelberg Presses: Widely used in the feeder sections of GTO, SM, and QM series machinery.
• Komori & Roland: Compatible with various sheet-fed offset models requiring 35mm flat suckers.
• Post-Press Equipment: Utilized in folding machines, collators, and high-speed mail inserters.

Applications:

• • Sheet Feeding: Providing the primary lift for paper sheets from the stack to the feed board.
  • Paper Separation: Assisting the air blast system in separating the top sheet from the pile to prevent doubles.
  • Packaging Machinery: Handling lightweight carton board and labels in automated packaging lines.

Equivalent Models:

• Heidelberg Part No. 00.580.4128: A functionally equivalent standard white rubber sucker used in many European machines.
• Standard 35mm Flat Sucker: Generic industry equivalent however, user should verify the 7mm hole size before replacement.
• Silicone 35×7 Variant: A high-temperature equivalent, although the rubber version provides superior friction for standard paper.
