Super Longlife
SL Series – Precision Roller Chains with Extended Service Life
iwis SL Chains – Precision Chains from the Super Longlife Series
JWIS SL chains are designed for a long service life. Their performance is based on high wear resistance, consistent manufacturing quality, and high breaking loads and fatigue strength that exceed the requirements of the relevant standards.
The Super Longlife technology was specially developed by iwis for highly stressed control drives in the automotive industry and has since been adapted for industrial applications.
A real added value for your application!
What makes the "Super Longlife" Roller Chains so durable?
Cross-Section of an SL Pin
- Surface layer with very high surface hardness
- The diffusion zone is a load-bearing, hard layer with high strength. Together with the surface layer, it forms the wear protection.
- The base material is the ductile core of the pin.
