Replacement suction cups and nozzles for bookbinding, perfect binding and saddle-stitching equipment.
Select the matching model and verify material, diameter, bore and machine compatibility before ordering.
Available variants include silicone, latex, rubber, polyurethane and wear-resistant compounds as listed.
Pack quantity is shown in the model name when applicable.
Compatibility references identify intended replacement applications and do not imply affiliation with equipment manufacturers.

Applications and Suitable Workpieces
These replacement suction cups and nozzles are intended for feeding, separating, lifting and transferring paper-based workpieces in printing and postpress equipment. Select the exact model by material, diameter, bore and machine interface rather than by color alone.
Recommended applications
Single-sheet pickup and separation of paper, printed signatures, book blocks, covers, labels and light cardboard.
Bookbinding, perfect-binding, folding, collating, saddle-stitching, case-making, die-cutting and other print-finishing feeder stations.
Heidelberg-, Kolbus- and TSK-compatible replacement positions only where the listed dimensions and mounting interface match the existing machine part.
Repeated high-cycle paper handling where mark-free pickup, reliable sheet separation and wear resistance are important.
Material and model guidance
Polyurethane and wear-resistant compounds: preferred for high-cycle operation and abrasive paper or board where long service life is important.
Silicone: suitable for flexible sealing on paper, printed stock and coated sheets; confirm that the selected hardness and contact behavior are appropriate for the printed surface.
Latex and soft rubber: useful for lightweight, uneven, wavy or pre-folded paper where a softer lip can improve conformity.
Multi-layer nozzles: provide additional stroke and height compensation for stacks, covers or workpieces with level variation.
Verify the actual paper weight, porosity, coating, ink condition, cup spacing, vacuum level and cycle speed. Porous stock and air-permeable cardboard may require multiple cups or a higher-flow vacuum system.
