1. Journal bearing. Hard face head bearing surface. The taper bearing is inlaid with antifriction alloy and then silver plated. The bearing capacity and bite resistance of bearings are greatly improved.
2, the O-ring is made of high-saturation nitrile rubber with higher wear resistance, which increases the sealing section. The sealing flange in the conical sealing area is precisely designed, which increases the reliability of sealing.
3. Bit bearing can be ball lock or ring lock. The bit with ring lock bearing can withstand higher bit weight and carry the ball
The lock bearing bit can be used for high-speed drilling.
4. The full rubber compensator can limit the pressure difference and prevent drilling fluid from entering the lubricating oil system, which provides a good lubrication guarantee for the bearing system.
