| Single Cone Bit Parameters | |
Type | HKA 8 1/2" 537 | |
IADC | 537 | |
Bearing Type | Journal Bearing | |
Grease Lubrication | Available | |
Grease Compensation System | Available | |
Palm Tip and Back protection | Welding with carbide inserted | |
Application | ||
Low compressive strength, medium soft, with hard abrasive interlayers formations, such as hard shale, anhydrite, soft limestone, sandstone, etc. | ||
1. HKA series of single roller bit adopts high toughness hard alloy teeth, and adopts optimized tooth arrangement structure design with tooth rows, tooth number, and exposed tooth height, fully leveraging the cutting ability of the insert bit.
2. The use of welding materials between the tooth palm and the second stop surface friction pair reduces the temperature rise of the friction surface, resulting in a longer working life.
3. Adopting a new type of material for dental palm and dental wheel, the dental palm adopts a symmetrical full diameter retaining structure, reducing friction between the back of the dental palm and the wellbore, protecting the dental palm tip and sealing, enhancing work stability, and increasing the quality of the wellbore.
4. Adopting vacuum oil injection method to reduce bearing pair wear; Steel ball locking teeth, suitable for higher rotational speeds.
