Great care should be taken when choosing materials in areas where there is a high risk of corrosion such as industrial use.

All casing parts can be powder coated to enhance corrosion resistance, or a stainless steel casing can be selected. All bearings are life-time lubricated and extra sealed for extended life. Vital parts such as bearing components are coated with tectyl for enhanced corrosion resistance.

Epoxy-coated foil (OC) should be selected. Epoxy-coated foil provides extremely effective protection against corrosion. Seawater-resistant foil (OK) with magnesium content is available; an alternative to epoxy-coated foil, it provides excellent corrosion protection.
