Auto Bearing NTN Factory Price 4T-30220 Tapered Roller Bearing

Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings have tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed. Single row tapered roller bearings can bear radial loads and single direction axial loads. When the bearing bears radial load, an axial component will be generated, so it needs another bearing that can bear the axial force in the opposite direction to balance it.

Characteristics of tapered roller bearings:

1.Suitable for heavy load mechanism, or impact load mechanism;
2.Can bear radial load and axial load at the same time;
3.Tapered stick bearings will have axial force, so they need to be used in pairs;
4.The operation speed is not suitable for high speed;
5.Good lubrication.
