Design features and structure
1. Mixed tooth arrangement design to improve the wear resistance of the roller cone, specifically designed for rotary excavation engineering;
2. Strengthen the back nail design to protect the cone body and extend its service life;
3. The straight plate type roller cone is more convenient for barrel drilling and welding.

Bearing
High precision rolling bearing, ball lock mechanism, bearing surface inlaid with wear-resistant alloy and silver plated. It has strong wear resistance and is suitable for high-speed rotation during drilling.

Sealing and lubrication system
The bearing circular sealing ring is made of HNBR rubber, which has the advantages of wear resistance, oil resistance, high rotational speed, and is suitable for use in various harsh conditions.
