date:
2022-08-29
Cutting structure: High-quality hard gold teeth with new formula and new technology are used to enhance the comprehensive mechanical properties of cutting teeth.
Main use: The roller cone is mainly used to assemble unconventional size drill bits, drill bits, machine pile drill bits, and reaming bits.
Bearing structure: Radial sliding with high precision, two thrust bearings, tight steel balls. The large journal of the tooth claw and the second stop surface are welded with wear-resistant alloy, the large hole of the cone and the second stop surface are de-embedded with special alloys and silver-plated, which increases the wear resistance and anti-seizure ability of the bearing pair and improves the bearing pair's ability to adapt to high speeds .
Gauge structure: Multiple gauge structures are adopted: the outer row of cones is inlaid with trimming teeth (GT teeth), the back of the wheel and the back of the claws are inlaid with hard gold teeth, and the claws are reinforced by surfacing with a resistant alloy. The gauge capacity of the drill bit.
