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.
iwis SL series chains (Super Longlife) have pins with an extremely hard surface. This special design shows outstanding characteristics: Highest wear resistance, a prolonged service life, high breaking and fatigue strength, low susceptibility to deficient operational lubrication, corrosion and frictional corrosion in the chain links.

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)
