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

JWIS Maintenance-Free Roller Chains are ideally suited for normal chain applications without relubrication, are wear-resistant, and have friction-optimized coating. The Maintenance-Free Roller Chain is made of a material specially designed, hardened, and treated to optimize its tribological properties. 

The JWIS Corrosion Resistant Roller Chain has high wear resistance if relubrication is done at regular intervals. This Roller Chain has long-lasting corrosion resistance in comparison with surface-coated chains as well as significantly higher fatigue resistance than stainless steel chains.
