1. Journal bearing. Hardfaced head bearingsurface. Cone bearing inlaid with friction reducing alloy and thensilver-plated. The load capacity and seizure resistance of the bearing isgreatly improved.
2. O ring seal is made of the more wearresistance high saturated buna-N with the increased seal section and preciselydesigned sealing flange in the cone sealing area increased the reliability ofthe seal.
3. The bit bearing can be ball locked or ringlocked. Bit with ring lock bearing can stand high weight on bit and bit withball lock bearing can be applied to high rotary speed drilling.
4. All rubber compensator is used which canlimit pressure differential and prevent drilling fluid from entering thelubrication system and this provides the bearing system with good assurance oflubrication.
5. New type of grease that can sustain hightemperature up to 250°C is utilized.
6. High wear resistance and excellent cuttingability of the insert bit are given full play by using carbide compacts of highstrength and high toughness in combination with optimized compact numbers androws, the exposure height and special shaped compacts. For steel tooth bit, thetooth surface is hardfaced with new type of wear resistant material and thusextended working life of the cutting structure while still maintaining highROP.
