Saving on the quality of crankshaft bearings is certainly the wrong approach, especially when it comes to tuned engines. That's why Stage6 is only working with with leading European and Japanese manufacturers such as SKF. The bearings are available in 2 versions - with low-friction, high-elasticity polymer cage for racing, and with robust metal cage for daily road use. Both types are also suitable for very high rpms and have the clearance necessary for crankshaft bearings. Sufficient lubrication and proper installation of crankshaft and bearings are prerequisites for long bearing life. The polymer cage version has higher elasticity and reduced friction. This is the type of bearing that we prefer for our racing engines. Please keep in mind that for this type of bearing ignition timing and carburetor settings have to be perfect, since the plastic cages are not built to take more than 120°C for a long time. This is also the reason why these TN9 bearings should not be used in engines with catalytic converters. Note: the open side of the cage has to face the crank webs. Note - The polymer cage bearings can only be used with exhausts or exhausts (original or tuning) without catalytic converter.
