QUANTITY: 1 x Axle Stopper and ball bearings -
NOTE: MB SlOT crowns are divided into 2 parts: the part with the ring gear and insert the wheel axle to keep in line with drive axle. Normally this part is fixed on axle wheels and runs with it, with 17020 is mounted on the wheel axle, held in place on one side by a stopper (19046) and the other from the ring gear, but is free to rotate independently of axle mounted on wheels because of the ball bearings The great advantage is the lack of friction between the sleeve and shaft, as with traditional systems there are, as the shaft leans when cornering and straight line on the insert that has revs / minute much lower . The lack of friction means more revs and smooth driving.
