Doppler Crankshaft Bearings (Polymer Cage)
Trying to save money by using low-quality crankshaft bearings with highly tuned engines doesn't seem like a clever idea. According to SKF, these can rotate up to 20,000 rpm and have of course a higher bearing clearance (C4). Sufficient lubrication and proper installation of crankshaft and bearings are of course essential for long life. The version offered here comes with a polymer plastics cage, which has higher elasticity and a reduced friction coefficient as compared to the metal ball cage. And by the way: This is the type of bearing that we prefer for our racing engines. What is also important is the right ignition timing and carburettor settings, since bearings should not be subjected to more than 120° for a longer time in order to prevent damages. 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.

Attention! Can only be used with engines that have no catalytic converters, i.e. only for scooters with tuning exhaust or original exhaust without converter.
