FAG 6205-C-TVH-C4 Deep Groove Ball Bearing – 25 x 52 x 15 mm, Open, C4 Clearance – Kart Crankshaft Bearing, TKM BT82 & TM KZ10

FAG 6205-C-TVH-C4 is a single-row, open deep-groove ball bearing from Schaeffler's Generation C range, used as the crankshaft main bearing in 2-stroke kart engines with a 25 mm journal. Confirmed fitments include the Formula TKM BT82 (25mm crankshaft side), TM Racing KZ10, and BMB EasyKart 125cc. Important: the most common 125cc TAG engines — IAME X30, Rotax Max, and Vortex ROK GP — use a 6206 C4 bearing (30mm journal), not this one. C4 clearance is designed for high-speed, high-temperature running where a tighter bearing would bind — essential in engines running to 15,000 rpm. Lightweight TVH polyamide cage (glass-fibre-reinforced PA66). Open construction lets the 2-stroke fuel-oil mix circulate freely. Fits a 25 mm shaft, 52 mm housing, 15 mm width. Basic dynamic load rating 15,900 N; limiting speed 21,600 rpm. New, manufacturer-fresh FAG stock.
