Iwis Offers Roller Chain with Combination of Coatings
August 28, 2019—
The new Iwis b.triton high-performance roller chain.
Wherever chains are exposed to the effects of seawater, or subject to stringent cleaning requirements, materials with conventional coatings soon reach their technical limits: roller chains used in harbors, or applications in the food or building services industry, rapidly lose their wear- and corrosion-resistant properties. The new b.triton series from Munich-based chain manufacturer Iwis can be utilized in harsh operating environments. It is particularly resistant to corrosion and wear.
High-performance zinc flake technology is combined with a special surface treatment, ensuring that Iwis b.triton chains are more resistant to corrosion than comparable competitor products in the market, as shown by the results of standardized corrosion tests. The new roller chains are highly sustainable, so they are particularly environment-friendly, especially as they are made from RoHS-compliant materials and free from hexavalent chromium (CrVI).
The basis of the newly developed chains is the strength of carbon steel combined with special surface coatings. This technology means the chains are ideal for use in highly corrosive environments requiring the characteristically high fatigue strength and tensile strength of carbon steel chains. A particular feature of the special zinc flake coating is its extremely good adhesion to the base material, which guarantees reliable protection of the roller chain against corrosion - even under the toughest operating conditions. An additional salt spray test with chains already in operational use confirmed that the chain is reliably protected against corrosion.
Special coatings on bushes and pins reduce wear in the b.triton chain bearings. Extruded bushes and rollers guarantee even better corrosion resistance, reduced run-in elongation and quieter chain running. The new lubricant iwiDUR G, which was specially developed for the applications in which b.triton chains are used, provides additional protection against wear and corrosion. As a result, the chains can be used in a temperature range from -10 °C to +130 °C - which can be extended to 150°C by using an alternative high-temperature lubricant.
