ITALKIT Needle Bearing 14x18x10 mm ref. VZY.314

The ITALKIT 14x18x10 mm VZY.314 small-end needle bearing is a universal part. The small-end needle bearing lets the piston pin turn inside the connecting rod on fine steel needles. On a two-stroke, it is lubricated only by the premix: it wears quickly and, if it breaks, it destroys the piston and the cylinder.
