Description Silver needle bearing Stage6 HQStage6 Small End Bearing HQ silver 12-to-10mm Adapter 10x17x13mm, Minarelli.We had this reducer bearing manufactured specifically for us; it allows for using crankshafts with conrods for 12mm piston pins on cylinders with 10mm piston pins. This way you can switch between high-end, sport and original cylinders without having to replace the crankshaft.Attention: The cage has an outer diameter of 17 mm and therefore does not fit all crankshafts (many have a diameter of 15 mm or 16 mm). We therefore recommend measuring the crankshaft beforehand.Small end bearing 10x17x13mm Questions about the product

Notes and Safety What is a Small end bearing?The small end bearing or piston pin bearing is a needle bearing; the rolling elements used are cylindrically shaped needle rollers. It works similarly to all bearings, reducing friction and increasing the life of the crankshaft and the cylinder.The small end bearing takes in the piston pin and reduces friction between the piston pin and connecting rod by distributing the load over a larger area.The small end bearing plays a vital role in the reliability and longevity of the engine, so it is important to replace and lubricate it well each time you reassemble the engine.Tuning Level: RacingWe categorize our products into different performance levels
