6206 Main Crankcase Bearing 30×62×16 mm

Part No.6206

OTT 6206 is a single-row deep groove ball bearing used as the main crankshaft (crankcase) bearing in popular kart engines, including ROK GP, IAME X30 and Rotax Max. It is an all-steel design: balls, inner ring and outer ring are made from 100Cr6 high-carbon chromium bearing steel (GCr15 equivalent), chosen for hardness, wear resistance and dependable running at high rpm. Kart engine builders fit it as a direct replacement when rebuilding an engine or renewing a worn main bearing. Always confirm the bearing specification your engine manufacturer calls for before ordering.
