RIGBRS - Crossed Roller Vs Ball Bearing – Compare from six aspects
28/8/2020· Crossed roller bearing vs ball bearing - Stiffness. Crossed roller bearings rollers are arranged crosswise on the raceway and have a larger contact area than ball bearings. Besides, cross roller rings clearance can be adjusted to negative clearance. Therefore, cross roller rings rigidity is 3~4 times greater than the ball bearings.

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.
