31311 C&U Tapered Roller Bearing 50X120X31.5mm

Description

The 31311 Tapered Roller Bearing  is identical to 30311 Tapered Roller Bearing in terms of  general dimentions. However, the 31311 bearing has a  larger cone angle, allowing it to support greater axial load.  While the 3o311 Tapered Roller Bearing is designed with a smaller cone angle, which sacrifices its axial load capacity but enhances radial load capacity. When choosing between them, the specific application requirements must be considered, as these two bearings are not interchangeable in most cases.
