Four-row Tapered Roller Bearings

Four-row tapered roller bearings are one of the mainly roll neck bearings and the capacity of their radial and axial loads is high. They can carry heavy axial loads in two directions, and their radial loads capacity is 3 times heavier than single-row tapered roller bearings. But the limiting speed is lower. They can be used as axial locating bearings in two directions because they are able to limit axial displacement in two directions within axial clearance. The radial and axial clearance also can be adjusted by changing the width of spacer between inner and outer rings.
