Roller bearings are used in all main shaft and auxiliary drive shaft applications to support pure radial load, and allow for axial shaft elongation due to temperature changes with no additional load effect on the bearing.
Angular contact bearing 184BA-2251(184*226*21.5) is used in excavator travel gearbox.
