Product introduct
67790-67720 Characteristics of large cone Angle tapered roller bearings:
The inclination Angle of the busbar of the outer ring raceway to the axial center line is 25° ~ 29°,(Good bearings, low prices, on ZH, look for bearings that suit you)
so it is called the large cone Angle tapered roller bearing. The bearing's ability to withstand axial load is higher than that of general tapered roller bearings, and it is mainly used to
withstand radial and axial combined loads dominated by bearing loads in one direction, but it is not easy to withstand pure meronal loads.
