Crankshaft bearing set ARTEK K1 XL racing SKF polyamide for Minarelli AM

ARTEK crankshaft bearing sets use high-quality SKF bearings and Corteco oil seals. SKF bearings are available in the required C4 tolerance and are suitable for speeds of up to 20,000 rpm. This is the polymer version and is more sensitive to engine tuning, as the polymer cages must not be exposed to temperatures above 120°C for prolonged periods. Correct tuning and carburetor setup are essential. For this reason, these bearings cannot be fitted to engines with catalytic converters. Attention: The half-open side must face toward the crankshaft.
