This is a 6205-size ball bearing with TNH (polyamide\/nylon cage) and C4 clearance rating, designed to handle the high RPM and thermal demands of competitive two-stroke kart racing. The KA100 uses two main bearings — one on each side of the crankshaft.\u003c\/p\u003e\n\u003cp\u003eMain bearings should be inspected during every bottom-end service and replaced if they exhibit roughness, play, or noise when spun by hand. Most engine builders recommend replacing main bearings at every full rebuild as a preventive measure. Always press bearings in and out using proper tooling to avoid damaging the crankcase bores.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 bearing (order 2 per engine)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA failed main bearing can destroy the crankcase, crankshaft, and seals in seconds.
