The outer ring or inner ring of two-row tapered roller bearing is a whole unit. ZZ’s two-row tapered roller bearings can be divided into metric and imperial ones. For metric tapered roller bearings, ZZ will match the tolerance and dimension of spacers for the two single-row tapered roller bearings before delivery. For the imperial tapered roller bearings, it mainly contains TDI (one complete inner ring and two single outer rings, it’s usually supply together with outer spacer)and TDO(one complete outer ring and two single inner rings)structure. The rotating precision of metric and imperial tapered roller bearings is different.
