or worm gear, the Timken engineered surfaces team works with customersto integrate toolbox of technologies that maximizethe performance of their products. Depending on the coating, Timken engineered surfaces can increase gearsscuffing and pitting resistance by more than 3%. Thegears torque capacity increases drastically or the pittingand scuffing life extends significantly. Timken offers four different surface treatments for vari- ous purposes: Spherical roller bearing with ES treatmentPlanetary sun gear untreated on the top and with ES treatment on the bottomES1/2 Topographical modification process: provides some wearand friction reduction in poorlubrication. ES3 Topographical modification process: provides some wearand friction reduction in poorlubrication, and increasesfatigue life. ES2 Moderately hard coating with low friction: providessuperior scuffing and frettingprotection to slidingcontacts, and fatigue-lifeenhancement to rollingcontacts. ES3 Hard coating with reduced friction: provides limitedscuffing protection, abrasionresistance and superiorfatigue-life enhancement torolling contacts.

We advise not only on bearing selection and cor- rect fitting practices, but also offer proprietary cal-culation tools for analyzing the bearing technologyof the machine design. Our engineers use powerful analytical software tool developed by Timken, to predict applicationperformance for the bearings, the gears, the shaftsand the housing. team of Timken sales and application engineers works continually with customers to ensure thatour products meet their needs.
