crankshaft bearing set ARTEK K1 racing SKF polyamide for Minarelli AM

In ARTEK crankshaft bearing sets high-quality SKF bearings and Corteco oil seals are used. SKF bearings are available in the required C3 tolerance and suitable for up to 20,000 rpm. This is the polymer version and is more sensitive to engine tuning, as the polymer shells must not be exposed to temperatures over 120°C for prolonged periods of time. Correct tuning and carb set up is a must. For this reason, these bearings cannot be fitted to engines with catalytic converters. Attention: Half open design.
