Tsubaki G8 Series Neptune corrosion-resistant chain

Click2Contact

Tsubaki’s G8 Series Neptune corrosion-resistant chain is an RS roller chain that combines protection against corrosive environments and maximum chain strength.

The company’s solution is based on a two-layer protection scheme applied to high-quality carbon-steel chain components. A top-coat resin protects the chain from physical impact and forms the frontline defence against corrosive agents. Beneath this is a base coating which prevents oxidisation from reaching the chain.

The coating system is applied prior to the chain assembly processes to ensure that each chain component is completely coated. The application process is at low temperature so it will not affect chain strength.

The result is a carbon-steel chain that can be used in wet environments and even underwater. It is available as roller chain and as single- and double-pitch conveyor chain. The conveyor chain is complemented by a range of attachments that have the same two-layer treatment.

The chain has good resistance against alkaline chemicals such as sodium hypochlorite and sodium hydroxide, which are commonly used in the food industry to clean and disinfect.

The coating is RoHS compliant and environmentally safe compared to other industry standard coatings such as lead, cadmium, mercury or arsenic. It is therefore suitable for use in industries that are phasing out hexavalent chromium from their plants.

With an operating temperature range from -10 to 50°C, the Neptune chain is suitable for food and beverage uses including food conveyors, meat processing, washdown areas, high-humidity areas, food packing machines and spiral conveyors.
