Tapered roller bearings belong to separated bearings which consis of inner ring,outer ring,tapered roller and a cage.it mainly carry radial loads and some unite load between radial and axis direction, normally it can not carry axis load separately.capability of load of bearing depand on angle degree of the raceway of outer ring, more bigger angle degree ,greater load will be carried. It is more extensive to be used in low speed equipment.
Single Row Cylindrical Roller Bearing is most popular in tapered roller bearing.small double row cylindrical roller bearings are used in hub of front-wheel drive for the past few years. Four row tapered roller bearings are used in large machine of cold or hot milling roll.
Except main type, there are also improved reinforced type、double row、four row 、big tapered angle、double inner rings and outer rings and washer tapered roller bearings.
