Tapered roller bearing—Single row circular cone roller bearings taper Angle formed in 10 ° 19, can also withstand before ° to load and radial load bearing joint action. Taper Angle is larger, the axial load capacity. Large taper Angle of bearings, the code and B, cone Angle in 25 ° 29 °, it can withstand the larger axial load. In addition, the single row circular cone roller bearings can be adjusted during installation clearance.
