Utilizing a twin wire arc thermal spray, the metallizing process restores bearing fits to OEM specifications. Your critical equipment is repaired, restored, and reconditioned, at less time and cost compared to a full replacement. The thermal spray/metallizing process applies a 420 Stainless Steel coating that performs well under compression and resists corrosion and erosion. The resulting twin wire arch thermal spray coating is suitable for applications in the wind & hydro power, marine, and other critical heavy equipment industries.
