The complete CJWinter line of tooling for cold root rolling rotary shouldered connections is compatible with any CNC lathe, and our in-house engineering staff is always available to help with technical manufacturing situations.
CJWinter once again expanded its cold root rolling product line to include the latest 11069 Series - designed for use in smaller rotary shouldered connections. The 11069 allows you to increase the fatigue resistance of your connections without slowing down your process.
The 11069-SA Series will roll all standard API Rotary Shouldered BOX connections in the following ranges.
NC31 thru NC38
3- 1/2 thru 4- 1/2 Reg
2- 7/8 to 3- 1/2 IF
3- 1/2 to 4- 1/2 FH
CJWinter has led the industry in supplying thread rolls and thread rolling tools around the world for 60+ years, and that experience informs the design for the 11069 Series, specifically crafted for Rotary Shouldered Connections in the petroleum industry.
Oil field and drilling tools demand strong connections. With tools like the 11069 Series, cold root rolling burnishes the thread root in rotary shouldered connections, strengthening them and providing a solution to costly, over-stressed or even failing thread roots. The process helps to avoid joint failures and can prolong the service life of drilling connections by three to five times.
