Corrosion is fatal to slewing bearing, it can directly affect the performance for machine, production lade time and so on. So that engineers pay more attention to this who can reduce the pollution of turning, machining, forging and storage. After that, we do different kinds of package to water proof, besides, we do special surface coating like sand blast, zinc coating and other oil coating.
Do coating to slewing bearing is essential to stay away from grave damage, from electrical zinc coating and hot dipped zinc coating to avoid eroding, Cr and Ni play a role in hostile environment.
Anti-corrosion oil or black oxide coating is only suitable for short-term protection against mildly corrosive environments. They are sometimes used to store slewing bearings before servicing. Zinc thermal spray provides deeper protection and provides a long-term solution.
