Roller bearings VS Ball bearings for Crank bearings - Tech Help/Race Shop - Motocross …

4/12/2020· Replacing the roller bearing with a ball bearing would likely require a small ball type bearing which would probably be better with thrust loads but much worse in radial loads. Because the flywheel and nut on the clutch side kindof keep everything from moving in the axial direction, thrust loads arent that high.
