Coating Bearings

Armoloy TDC and XADC Armoloy

Armoloy® TDC and XADC-Armoloy® coatings provide absolute adhesion and corrosion protection equal to 440 series stainless steel. This allows the use of metals that are less expensive, easier to machine, more resistant to fatigue, and longer-lived. Armoloy can successfully coat ball, roller and linear bearings to Abex 9 classification. Dimensional stability is maintained with engineered deposits from .000050/.0002”.

The nodular surface of the Armoloy® coatings allows the coating to work against itself, increasing wear and lubricity characteristics in roller and needle bearing applications and allowing them to be completely coated. Bearing operating temperature may be reduced when Armoloy® coatings are applied. Surface hardness is increased to 78 Rc with Armoloy® and to 98 Rc with XADC-Armoloy® coating.
