SKG series bit is designed with roller bearing and rubber O-ring
seal . This bit can achieve longer footage and higher ROP when
drilling under medium to low WOB and high RPM.
The size range of SKG series bit is from *0 5 /8 to *6 inch, and
IADC varies from **4 to **5 .For example :*7 1/2 SKG**5G.
#MAIN STRUCTURE FEATURES
1.Roller
bearing structure .with rollers arranged in grooves recessed in
the cone body ,the size of the bearing journal is increased ,
therefore, with the ability of enduring high WOB and applying for
high RPM.
2.All
rubber compensator is used which can limit pressure differential
and prevent drilling fluid from entering the lubrication system
and this provides the bearing system with good assurance of
lubrication.
