Inserted Tooth Roller Cone Bit Blue SRI API 3 Cones Bit

SRI (Slide Bearing-Rubber Sealing Inserted Tooth) bits can load a higher WOB in normal RPM condition. It applies in different formation from very soft to very hard matched with different cutting structure.

Product Features:

- Slide bearing is applied

- Cone bearing is silver coated which provides more loading ability and anti-seizure ability

- O sealing ring is made of HNBR which is more corrosion and high temperature resistant; larger sealing ring cross section increases sealing adaptability

- Steel ball locked cone provides more security and is applicable to high speed rotation.

- 250 ℃ high temperature and anti-corrosion lubricant is applied which the high temperature resistance performance of bit sealing lubricating system.

- High strength and high flexible hard alloy teeth are applied to improve the anti-impact performance, reduce tooth breaking rate.

- Optimized milled teeth quantity and teeth arrangement structure give full play to the cutting ability and cutting speed of drill bits.
