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.

Design Attributes
Four single cups for optimum load sharing.
Cup spacers available with or without lube groove and holes.
Improved surface finishes to enhance lubrication performance.
Inboard and outboard cone face slots that reduce cone face wear.
Spiral bore grooves with blended radii to eliminate roll neck damage.
Case-carburized components to improve toughness and increase fatigue life.
Patented seal designs with improved contact geometry for enhanced sealing.
Enhanced roller profiling for even load distribution, which reduces edge stress.
No central cone or cup spacers to minimize number of components to be handled.
Effective sealing at cup outer diameter (OD) to seal contaminants away from bearing OD and chock bore.
