1. High precision journal bearing with two thrust faces. Head bearing surface is hard faced. Cone
bearing is inlaid with friction reducing alloy and silver-plated. The load capacity and seizure
resistance of the bearing is greatly improved.
2. Precise metal face seal. The two dynamic axial sealing rings of the sealing system are metal
seals, and two highly elastic rubber energizers are seated separately in head and cone
sealing areas functioning as static seals. Optimized sealing compression ensures good contact
between the two metal sealing faces at all times.
fluid from entering the lubrication system and this provides the bearing system with good
assurance of lubrication.
compacts with high strength and high toughness in combination with optimized number of
compacts and rows, compact exposure height and special shaped compacts. For steel tooth bit.
the tooth surface is hard faced with new type of wear resistant material and thus working life
of the cutting structure is extended while high.
