Disclosed is a taper roller bearing. The taper roller bearing includes an inner wheel, an outer wheel, and a taper roller functioning as a rolling element interposed between the inner wheel and the outer wheel. The no-load rolling rotation center (AP) of the taper roller is positioned to be more inside than the rotation center (BAP) of the taper roller bearing for a certain drop amount. Therefore, the taper roller bearing improves the durability of the taper roller and extends the service life of the taper roller by enabling the smooth rolling rotation of the taper roller. |
