146mmIADC321 tricone bit
1, Structure features:
1. Rolling seal bearing structure, cylindrical roller cone in slots in the body, increasing the shaft neck size.
2. Thrust bearing vice respectively by grinding surface treatment and hardening process.
3. The differential pressure and prevent drilling fluid restrictions in the lubricating system all rubber oil storage sac, for bearing system provides good lubrication guarantee.
4. Steel ball lock die, suitable for the high speed.
5. The 250 ° C high temperature resistance, abrasion resistance of new grease.
Product advantage:
GA series bit for O form rubber sealing roller bearing drill bits; low pressure for the high speed drilling drilling; it is an ideal and economic tools
