SKH Series Roller Cone Drilling Bits
SKH rubber sealed bit with journal bearing
SKH series bit adopts journal bearing rubber 0-ring seal along with more aggressive cutting structure. This bit is with the features of longer footage and higher ROP and is the ideal choice for drilling applications in upper homogenous formations.
The size range of SKH series bit is 8 1/2 – 17 1/2 inch and its IADC code is 116 – 537.
Main structure features:
· Hardfaced head bearing surface. Inner hole of cone is silver-plated.
The load capacity and seizure resistance of the bearing is greatly improved.
· 0 ring seal is made of the more wear resistance high saturated buna-N with the increased seal section and precisely designed sealing flange in the cone sealing area increased the reliability of the seal.
· 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 still maintaining high ROP.
