Product Information

JWIS Roller chains are characterised by an above-average service life due to excellent wear resistance, high consistency, matchless precision and a considerably higher breaking strength and fatigue strength than required by ISO standard. All iwis chains are pre-stretched and are provided with a highly efficient initial lubrication.

Highlights:
  • Only high-quality heat-treated and case-hardened steel is used with stringent specifications for materials analysis, tolerances and surface quality
  • Each chain part is manufactured a million times daily to the same precision and is monitored using SPC (statistical process control)
  • All chain parts are heat-treated, in some cases using special processes to optimize quality characteristics
  • Modern production technologies ensure consistent geometry and superior surface quality
  • Chains are checked for dimensional accuracy, length tolerance and flexibility, plus for the press fit joins on pins, outer plates and bush, and inner plate
  • Our high quality assurance standards comply with the requirements of ISO 9001:2006
  • For special applications: surface coatings, special lubricants, special materials (e.g. corrosion-resistant)

Applications

  • Warehouse technology, materials-handling industry
  • Conveyor technology
  • Assembly and industrial handling systems
  • Wood processing industry
  • Mechanical engineering and systems construction
  • Glass, ceramic and building material industry
  • Environmental technology, Recycling
