Repeatability is built into each attachment with a positive stop. This feature ensures that the set thread size will be reproduced time after time without variation.

Penetration (Roll Feed) Rate Quickly Adjusted is easily changed through the flow control valve. This allows rolling of the material as fast as it will flow, maximizing roll life.

Pitch Diameter Quickly Adjusted by turning an easily accessible adjusting knob. Minimizes machine down time for adjustment. Allows you to make within .0002 inches without stopping.

Equalized Rolling Pressure eliminates side pressure on parts and machine spindles. The pinch system allows threads to be rolled at a greater distance from the collet and ensures outstanding thread concentricity. The equalized rolling pressure automatically supports the part.

If your application is straight threads, taper pipe threads, knurling or the need to thread roll close to a shoulder then allow CJWinter to match your application with an Air Powered Pinch Style Thread Rolling Attachment today.

Thread Rolling for the Oil and Gas Industry -

In support of our unwavering commitment to be the supplier of choice CJWinter offers a comprehensive line of thread roll products for the Oil & Gas Industry that conform to the API Specification.  If you manufacture Sucker Rods, Pony Rods, Sinker Bars or Couplings, in either AISI Grade or API Grade Alloy's, CJWinter is the Best Choice for your thread rolling needs. Sizes available in 5/8", 3/4", 7/8", 1" & 1 1/8" body diameter's. Premature thread wear can cause catastrophic failures that could cost companies thousands of dollars. Every effort should be taken to extend the life of your connections. If the friction load develops between the pin shoulder face and the coupling shoulder face, and the preload begins to loosen, the shouldered connection will fail. If the stress fatigue cracks begin along the thread root and consolidate into major cracks, the pin connection will fail. CJWinter will evaluate your application requirements and recommend the best thread rolling dies providing you thousands of additional pumping cycles.

If your product line is Rotary Shoulder Connections, Sucker Rods, Threaded Bolts or API Connections for Onshore or Offshore applications, CJWinter’s thread rolls and burnishing rolls will meet your production requirements. CJWinter is well positioned to meet the ever-evolving needs of the oil and gas industry. Turn to CJWinter for attentive service and the newest technology designed to maximize the value and life of your oil and gas assets.  We know your goal is to supply your customers with the highest quality products that will produce in the most harsh and challenging environments.

For our customers thread rolling Sucker Rods, Pony Rods, and Bolts, burnishing the root of your API Pin and Box connections results in advantages such as greater efficiency and increased fatigue life, by minimizing crack initiation, improving strength and smoother operation. This process significantly increases the load or pumping cycles a connection can endure, without fracturing.

CJWinter’s thread rolls and burnishing rolls can be used on CNC, manual and automatic machinery.
