SL Series – Precision Roller Chains with Extended Service Life
iwis SL Chains – Precision Chains from the Super Longlife Series
SL chains from the JWIS brand are high-precision roller chains designed for maximum durability. Thanks to their exceptional wear resistance, outstanding running smoothness, unmatched precision, and significantly higher tensile strength and fatigue resistance than standard requirements, they deliver a substantially extended service life.
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.
All SL chains are marked with the SL suffix in our JWIS catalog.
