Tapered roller bearing is refers to the roller for rolling bearing radial thrust tapered roller type. A small cone Angle and big cone Angle two. Small cone Angle mainly bear radial direction load primarily radial and axial loads, often used in pairs, reverse installation, inner and outer race can be installed separately, in installation using radial and axial clearance can be adjusted; Big cone Angle mainly bear axial load primarily of axial and radial load, is generally not used to bear alone the pure axial load, as to the configuration (end with the same relative installation) can be used to carry pure radial load.

Tapered roller bearing type code 30000, tapered roller bearing for separating type bearing. In general, especially in the GB/T307.1-94 "rolling bearing centripetal bearing tolerance" involved in within the scope of the size of the tapered roller bearing outer ring and inner components is gm's one hundred percent can be used interchangeably.
