Oil and Gas Tricone Rock Bits for Hard Rock
Description:
1. Elasatomer Sealed Roller Bearing Bit
Cutting Structure: The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.
Gauge Structure: Multiple gauge protection with gauge trimmers on the 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. 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", 13 5/8", 14 3/4", 15", 15 1/2", 17 1/2", 22", 24", 26", etc.
IADC Code: 1-- Series, 2-- Series, 3- Serie
2. Air Cooling Roller Bearing Steel Tooth Bit
Cutting Structure: The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit
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: 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: 1-- Series, 2-- Series, 3- Series
3. Non-Sealed Roller Bearing Steel Tooth Bit
Cutting Structure: The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces.
Bearing Structure: Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the probability of cone Cdropping to minimum
Main Type Available: Size: 2 3/8", 3", 3 5/8: ", 3 7/8", 4", 4 1/2", 4 5/8", 4 3/4", 6", 6 1/2", 7 1/2", 7 7/8", 8 1/2", 9 1/2", 9 5/8", 9 7/8", 10 5/8", 12 1/4", 17 1/2", etc.
IADC Code: 1-- Series, 2-- Series, 3-- Series
4. Metaled sealed Journal Bearing Steel Tooth Bit
Main Type Available: Size: 2 3/8", 3", 3 5/8: ", 3 7/8", 4", 4 1/2", 4 5/8", 4 3/4", 6", 6 1/2", 7 1/2", 7 7/8", 8 1/2", 9 1/2", 9 5/8", 9 7/8", 10 5/8", 12 1/4", 17 1/2", etc.
