F-M PT_IROX 2 bearingIROX 2 is a new range of polymeric coated crankshaft bearings from Federal-Mogul Powertrain. The company says it has developed this technology to reduce friction and improve the wear resistance and fatigue limit of the bearings used in downsized engines.

The bearings have an overlay that is a PAI (Polyamide-imide) polymer resin binder containing a number of additives dispersed throughout the matrix. These new polymer coated bearings can be used in both light and heavy-duty engines, and are effective in hybrid and start/stop applications that place additional demands on bearings through frequent re-starting, says Federal-Mogul.
