Kit Roulement Principal et Joint de Vilebrequin - Polaris Trail Blazer 250 2000

All Balls Crank Bearing and Seal Kit

All Balls crankshaft seal and mainbearing kits combine Koyo high quality, precision engine bearings with, where appropriate, double lip seals.

Koyo bearings are widely used in engines and are supplied as original equipment to many motorcycle and ATV manufacturers.

Where included, the double lip seal utilises a teflon contact area, resulting in less wear on the crankshaft pin and can tolerate a 'dry start' without failure.
