Metallizing

Increase reliability by restoring bearing fits to factory specifications or better by metallizing and precision grinding. A twin wire arc process using 420 stainless steel material with a bond strength in excess of 6000 psi provides a superior bearing fit surface that is more resilient to fretting and corrosion.
