1. Metal-face sealed bearing Tricone Bit
Cutting Structure	The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
Gauge Structure	Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
Sealed Bearing Structure	1.Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed. 2.The advanced metal seal package will improve the reliability and durability of bearing seal.
Main Type Available	Size: 6",6 1/2",7 1/2",8 1/2",9 1/2",9 5/8",9 7/8",12 1/4",17 1/2", etc. IADC Code:4-- Series, 5-- Series, 6-- Series,etc.

2. Elastomer sealed bearing Tricone Bit
Cutting Structure	The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit.
Gauge Structure	Multiple gauge protection with gauge trimmers on the heel of cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
Sealed Bearing Structure	1.Abrasion resistance and seizure resistance of the bearing are improved. 2.Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance.
Main Type Available	Size: 5 7/8",6",6 1/2",7 1/2",7 7/8",8 1/2",9 1/2",9 5/8",9 7/8",12 1/4",14 3/4",17 1/2", etc. IADC Code:4-- Series, 5-- Series, 6-- Series,etc.

3. Air Cooling Roller Bearing Tricone Bit
Cutting Structure	The durability of premium tungsten carbide insert is improved with new formulas and new techniques and new techniques.
Gauge Structure	Gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability.
Sealed Bearing Structure	Air cooling roller bearing package. Balls lock the conewhich reduces the probability of cone-dropping to minimum.
Main Type Available	Size: 8 1/2",9 1/2",9 5/8",9 7/8",10 5/8",12 1/4", etc. IADC Code:5-- Series,6-- Series,7--
