Working principle

Working principle

Tapered roller bearings are mainly subjected to combined radial and axial loads based on the radial direction. The bearing capacity depends on the raceway angle of the outer ring, the larger the angle, the greater the bearing capacity. The tapered roller bearing has a tapered inner ring and an outer ring raceway, and the tapered rollers are arranged between the two. All the projection lines of the cone surface converge at the same point on the bearing axis.
