Product description
1. Journal bearing. Hardfaced head bearing surface.
Cone bearing inlaid with friction reducing alloy and then
silver-plated. The load capacity and seizure resistance of the bearing
is greatly improved. 2. High wear resistance and excellent cutting
ability of the insert bit are given full play by using carbide compacts
of high strength and high toughness in combination with optimized
compact numbers and rows, the exposure height and special shaped
compacts. For steel tooth bit, the tooth surface is hardfaced with new
type of wear resistant material and thus extended working life of the
cutting structure while maintaining high ROP. 3.HJ series bit uses the
most advanced sealing technology in the world, i.e. the metal face seal
(MFS). It can perform consistently in high speed drilling applications,
and is the ideal tool for drilling directional and horizontal wells. In
comparison with conventional rubber O-ring sealed bits, the average
working life (total drilling hours) of HJ series bit under the condition
of the same operating parameters can be increased by 35%.
