SKF Series Roller Cone Drilling Bits
SKF rubber sealed bit with floating bearing
SKF series bit is a kind of high efficiency bit for vertical and directional drilling applications, especially suitable for these kinds of drilling applications in relatively homogenous formation with good drillability.
This bit is designed with floating bearing and rubber ‘O’ ring seal, and also utilizes optimized cutting structure and enhanced gage protection technology and therefore, it can achieve longer footage and higher ROP.
The size range of SKF series bit is 8 1/2 – 12 1/4 inch and its IADC code is 117 – 537.
Main structure features:
This series bit adopt the bearing and seal system with the feature of low relative linear velocity of bearing couple and low temperature of friction surface. Applying of new type of synthetic grease enhance the ability of resisting high temperature, wear and extreme pressure of bearing, which can get longer service lift and higher reliability in vertical well and directional well.
Optimize culling structure of insert bits, choose offset crested scoop compacts with strong attacking ability as main cutting compacts, so as to make the bit with the feature of longer footage and higher ROP.
Properly arrange compacts on Head OD to enhance the security of bit 1n directional well. As well as improve the drilling operation in reducing well section or under the situation of up-reaming.
