Product Profile :

Using high strength and high wear resistance hard alloy teeth, improve the strength of the tooth and wear resistance. The new rolling bearing structure, greatly extended the bearing the working life, is under high pressure and high speed drilling to ability. Thrust bearing using high hardness and high wear resistance materials, further improve the bearing life.
