SL-Precision chains: The low-maintenance solution
SL- Chains are precision chains of the Super Longlife series of iwis.
SL Chains enjoy an optimal service life because they combine extreme wear resistance, highly even running, unmatched precision and significantly higher breaking forces and fatigue strength than the relevant standard requires.
The Super Longlife Technology was specially developed by iwis for the extreme loads found in timing drives and industrial applications.
Added value for your application, offered exclusively by iwis.
Highlights
-
All pins undergo surface treatment to optimise their wear resistance
-
SL pins therefore have an extremely hard surface and require little maintenance
- SL roller chains are highly impact-resistant
- Highest wear resistance
- Longer service life
What makes Super Longlife Chains (SL) so enduring?
Cross-section of an SL pin
- Peripheral layer with very high surface hardness
- Diffusion zone: a hard, load-bearing high-stability layer which, together with the peripheral layer, provides wear resistance.
- Base material: ductile core of the pin.
