• Single or douple chain 1/2 x 5/16 inch to DIN 8187-1/ ISO 606
• Grip with 1 or 2 tips, speccial design on request.
• Retention force is dependent on material conveyed and spring design – different number of coils and wire spring diameters available
• The gripper opens when it runs against a control disc (e.g. sprocket hub), causing it to swivel away outwards
• Higher retention force in comparison with 1-tip grip chain
• Food-grade initial lubrication
• Sprocket designs on request
• Mega-Life-Chains on request
• Chemical-Nickel-Plated-Chains on reques
• CR-Chains on request
• Limited length tolerances on request

• iwis high-performance chains with excellent wear resistance
• Minimal initial elongation due to optimum pre-stretching
• High rigidity also enables applications in long machines
• Basic chain versions are chemically nickel-plated / MEGAlife maintenance-free versions are available on request
• Identical chain lengths (within the selected tolerance range) ensure excellent running characteristics in both synchronous and parallel operation
• Differing levels of spring force allow an extremely wide range of materials to be gripped gently and held securely
• Chains with restricted length tolerances can be produced
• Recommended maximum running speed:
  → 2 m/s for the 1/2“ grip chain
  → 0.6 m/s for the 5/8“ grip chain
• Different control geometry is required for higher running speeds.
• iwis provides complete, ready-to-install solutions!

• Chains for Multivac systems can not be offered by iwis
• Packaging industry, especially foil packaging
• Electronic industry and manufacture of printed circuit boards
• Feeding in thin-walled sheet, plastics and other hard materials
• e.g. for punching, welding, filling, coating, cutting, stretching, shaping, sealing etc.
