Black Oxide Coating Protects Ball Bearing Inserts

Developed to provide resistance to mechanical abrasion, corrosion by mineral acids, salt solutions and atmospheric oxidation, KML Bearing Canada’s black, lustrous, strongly adherent oxide-coated ball bearing inserts are suitable for washdown applications. The coating process consists of mechanical or a chemical surface pre-treatment, formation of the oxide and converting the coated oxide to tenacious nature by a heat treatment. Pre-treated substrates are then subjected to surface oxide coating in an aqueous media. A triple-lip seal protects the grease and the internal components from contamination and early deterioration.
