Four-row tapered roller bearings are generally composed of two double-row inner rings, one double-row outer ring and two single outer rings. There is an inner spacer between the two inner rings and two between the three outer rings. The spacer ring can adjust the play.

When the four-row tapered roller bearing bears a large radial load, it can bear the axial load in two directions at the same time, but the allowable speed of the bearing is not high. Since the hole is inclined, if it is inclined, the rollers and raceways of the bearing will generate additional stress, which will increase the load of the bearing and shorten the service life of the bearing.

According to the structure, the four-row tapered roller bearing can be divided into two structures with seal and without seal, such as: 3806/254-2LS, 382948X2-2LS, BT4B328468G/HA1 is a sealed four-row tapered roller bearing.

Sealed four-row tapered roller bearings are the development trend of roll bearing technology in recent years. to make.

It has large bearing capacity and high precision requirements, and is used in harsh environments and poor lubrication conditions.

According to the cage structure, the four-row cylindrical roller bearing can be divided into two structures: stamping cage and pillar welding cage.
