Description:

Parameter

Series: rubber rings-rolling bearings(SRT¡Á¡Á¡ÁG)

Description:

Characteristic of bearing structure:
1. S.U.G SRT¡Á¡Á¡Á,SRT¡Á¡Á¡ÁG series tricone bit useSealed roller bearing structure. With rollers arranged in grooves recessed in the cone body, the size of the bearing journal is increased.

2. Thrust bearing surfaces are hardfaced and treated with friction reducing technology.

3. Ball locked cone, suitable for high rotary speed.

4. New type of wear resistant grease that can sustain high temperature up to 250¡ãC is utilized.

Characteristic ofPredominance technology

S.U.G SRT¡Á¡Á¡Á,SRT¡Á¡Á¡ÁG series milled tricone bit is rubber O-ring sealed roller bearing bit, which is the economical and ideal tool for drilling applications where high RPM and medium to low WOB are required.
