Roller bearings are loaded according to the number of columns roller into single row

Roller  bearings are loaded according to the number of columns roller into single row, double row and four row tapered roller bearings, such as different structural types. Single row  roller bearings can support radial load and axial load in one direction. When the bearing radial load, will produce an axial component, so when you need another can withstand axial force in the opposite direction of the bearing to be roller bearing.The ability to single row tapered roller bearing axial load depends on the contact angle, ie the angle of the outer ring raceway, the greater the angle, the greater the axial load capacity. Tapered roller bearings are up to the amount of split roller bearing row tapered roller bearings. In the car's front wheels, and spend the small size of the double row tapered roller bearings. Four tapered roller bearings used in large-scale cold rolling mill and other heavy machines. Features: Tapered roller bearings are mainly used to bear radial load mainly radial and axial load.
