 The Advantages of GXOAP alternator pulley

IATF 16949 certificate
  • High-quality material of mandrel, heat treatment process, production process, and product hardness, wear resistance, the accuracy of runout, and vertical difference of the products. We will not list this one by one. Because as an OAP manufacture, these process requirements must be met.
  • About surface finish of mandrel, needle roller, and outer ring. At present, our company is manufacturing according to the bearing international standard 0.2Ra, this can reduce the wear between parts, increase the service life of products.
  • The position and perpendicularity of the needle roller are also the advantages of our company. The reasonable position degree of the needle roller is an important factor and the key to guarantee the product not slip.The perpendicularity is the guarantee of affecting the straight running of the needle roller.
  • slipping normally appears due to the volatilization and oxidation of the grease in the later stage, the grease is reduced, and the wear of each friction surface is increased. our company adds a special device of insurance on the cold extrusion mandrel. When the needle roller is pushed into this position, the alternator pulley will lock the bearing in this position. About the grease, we asked a German company to help us design and produce the grease. It can keep the pulley works well, no matter in the low temperature and high temperature. that is to say, it will never slip.
