2 AI Series Oil Field s AI Series Oil Field s from itachi itachi AI series Oil Field s are designed and built to provide maximum performance and reliability for oil field service. These exceptional chains possess the highest fatigue strength ratings and shock load resistance compared with any standard chain series we currently build. Engineering and Technical Specifications Solid bushings and rollers Ballized pitch holes Wide waist link plates ress fitted center link plates for multi-strand chains atented high energy mechanical treatment for pins Shot peened rollers and bushings Unique bushed multi-strand connecting links Factory applied hot dipped wax type pre-lubricant Special 4-pitch riveted type offset links available atented Stainless Steel blast for link plates Q American etroleum Institute License Number 7F-005 Bushed Type Multi-Strand Connecting Links itachi AI Oil Field chain connecting pins possess unique bushed center plates. The bushing provides a press fit to the center plates that improves fatigue strength. These connecting links possess the same dynamic capacity as the base chain yet are easy to install in the field. Ball Drifted Link lates After heat treatment, link plates on itachi AI series Oil Field s are ball drifted to eliminate small imperfections and impart beneficial compressive residual stresses while improving fatigue strength providing greater reliable service life. 1

3 AI s, Features and Benefits Fatigue Inspire Series Former SBR Competitive Brand Compressive Residual Stress Zones Compressive stress has long been known to improve fatigue strength. Sources of compression in existing chain products include shot peening, high interference fits between pins, bushing and side plates, and the carburized zone found on pins and bushings. Our unique patent pending i-energy Mechanical Treatment imparts substantial compressive stresses to the chain components (see chart below) resulting in a 45%-50% increase in fatigue strength. orsepower ratings as well as the rated working loads are the highest in the world Relative ercentage Triple Zone ardness Wear rotection A residual, but important benefit of itachi s new i-energy Mechanical Treatment is that an ultra-high hardness shell is developed on the surface of carburized pins. This effectively gives these wearing components three layers of hardness protection: 1. Ultra-high hardness shell (Black Zone - See Below). igh hardness carburized case (Blue Zone - See Below). Core hardness (Orange Zone - See Below) Compressive Stress (SI) Thousands Compressive Residual Stress Measurements Inspire Series in vs. Standard Carburized in Inspire Series 50 Standard in Surface Depth From Surface (inches) Compressive stress measurements. The deeper trough of the INSIRE SERIES SBR pin means that the part has more compressive residual stress and is therefore more resistant to fatigue failure. Micro ardness Measurements Micro hardness measurements of the pins reveal an ultra-hard shell which fights chain elongation far better than can be achieved with conventional carburized parts. Benefits Summary Greater resistance to fatigue failure. Longer wear life due to high hardness shell. Smaller chain sizes required (igher ratings). Corrosion protection from proprietary stainless blast. ardness (Rc) Surface Inspire Series Standard in Black Zone Blue Zone Core Zone Core Depth from Surface (inches)
