JinHang Precision Bearing Co.,Ltd Four-row tapered roller bearings are the one kind of roll neck bearings,their radial and axial loading capacity are high,can carry heavy axial loads in two directions,and their radial loading capacity is 3 times heavier than singe-row tapered roller bearings, but 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. Four-row tapered roller bearings are mainly used in the working roll necks of hot or cold rolling mills, and roll neck of cogging mills. They usually clearance fit with roll necks to being mounted and dismounted conveniently. Steel pressed cages are usually used in four-row tapered roller bearings,and pin-type cages are for large-size ones.
