Especially with high-performance engines you should not be too stingy when it comes to buying crankshaft bearings. This is why Stage6 only collaborates with leading European and Japanese manufacturers of bearings and oil seals such as SKF and Corteco. We offer you these high-quality crankshaft bearing kits in 2 versions, with metal cage or with polymer cage. Both types can, according to SKF, be used up to 20,000rpm and have of course the necessary bearing clearance (C4). Sufficient lubrication and proper installation of crankshaft and bearings are of course essential for long life. The version with polymer plastics cage has higher elasticity and a reduced friction coefficient as compared to the metal ball cage. This is also the type of bearing that we prefer for our racing engines. What is important for these bearings is the right ignition timing and carburettor settings, since bearings should not be subjected to more than 120deg for a longer time in order to prevent damage. This is also the reason why the TN9 bearings should not be used in engines with catalytic converters. Please keep in mind that the half-open cage must be inserted so that it faces the crank webs. This metal cage bearing on the other hand is more resistant than the polymer version, but unfortunately it also generates more friction and hence more heat, which results in a shorter life expectancy.
