Product Description

 

                                                                                                                  Overview
     With the complexities and challenges of drilling in mining, Feilong Retop has developed a line of roller cone bits well suited for these applications.
    A complete and professional production process ensures each part of rock bit is produced strictly to meet customers' expectations.Through technological advancements in seal, bearing, compensation, cutting structure, and hydraulics coupled with proprietary bit design capabilities. This advanced roller cone provides industry leading reliability and drilling performance.

                                                                    Product Features
Seal and Lubrication
Premium HNBR O-ring, optimal seal compression and curved seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.

Lug Back Enhancement  
Carbide inserts are strategically arranged on lug back to improve bit's protection in abrasive formation,which can expend working life of the bit
 

Replaceable Nozzles Design

Replaceable nozzles with either nail retention or snap ring retention are supplied for the best hydraulics possible
 

Protection for Cone Shell

A row of carbide inserts is added between the outer row and the back cone rows to trim hole wall and protect cone shell

Shirttail Hard Facing

To ensure greater durability, we have welded carbide layer on shirttail that significantly increases wear resistance in this critical area of the bit
