圓錐滾子軸承屬于分離型軸承,軸承的內、外圈均具有錐形滾道。該類軸承按所裝滾子的列數分為單列、雙列和四列圓錐滾子軸承等不同的結構型式。單列圓錐滾子軸承可以承受徑向負荷和單方向軸向負荷。當軸承承受徑向負荷時,將會產生一個軸向分力,所以當需要另一個可承受反方向軸向力的軸承來加以平衡。圓錐滾子軸承廣泛用于汽車、軋機、礦山、冶金、塑料機械等行。在安裝和使用過程中可以調節軸向游隙，也可以預過盈安裝。

    Tapered roller bearings belong to separable bearings, bearing inner and outer rings all have conical raceway. The bearings are divided into single row, double row and four row tapered roller bearings according to the number of rollers. Single row tapered roller bearings can withstand radial load and uniaxial axial load. When the bearing is subjected to radial load, it will produce an axial component force, so when another bearing that can bear the reverse axial force is needed to balance it. Tapered roller bearings are widely used in automobiles, rolling mills, mines, metallurgy, plastic machinery and so on. During installation and operation, axial clearance can be adjusted and pre interference installation can also be made.
