China Custom Four Row Tapered Roller Bearings with Good quality

Four Row Tapered Roller Bearings

Four-row tapered roller bearings are 1 type of roll neck bearings. Their radial and axial loading potential are substantial. They can have axial loads in 2 instructions, and their radial loading potential is 3 times heavier than solitary-row tapered roller bearings, but the restricting speed is reduced. They can be employed as axial locating bearings in 2 directions because they can restrict axial displacement in 2 instructions within axial clearance. The radial and axial clearance also can be altered by changing the width of the spacer amongst the interior and outer rings. They are used almost solely in work roll apps this sort of as rolling mills. You can get four-row tapered roller bearings in the TQO and TQI patterns.

TQO design bearings (experience-to-face arrangement)

TQO design and style bearings have 2 pairs of tapered roller and cage assemblies. The 2 rows of rollers of each and every pair are organized confront-to-confront. Simply because TQO is the most broadly employed 4-row tapered roller bearing design, We manufacture this design and style in several variants.

  • Open or sealed.
  • With cylindrical or tapered bore.
  • With or without inner ring extension on each sides.
  • With or without a helical groove in the bore.

TQI style bearings (back-to-again arrangement)

TQI style bearings have 2 pairs of tapered roller and cage assemblies. The 2 rows of rollers of each pair are organized back-to-back. These bearings offer fairly rigid bearing arrangements, which can accommodate tilting moments. TQI style bearings are also used for vertical rolls of common mills. In individuals applications, the bearings are generally mounted with an interference in shape on the roll neck by applying a bearing design and style with a tapered bore. In this situation, a bearing with a cylindrical bore is required since the inner rings have a unfastened in shape on their seat, and the outer rings are mounted with an interference match in the chocks.

  • With cylindrical or tapered bore.
  • With or with out interior ring extension on 1 aspect.

Functions of four-row tapered roller bearings

  • Effectively-allocated loads on the four-row rollers.
  • Utilizing substantial hardness bearing steels as a result assures greater dress in resistance and long work existence.
  • Large radial and axial load capacity in 2 directions.
  • Separable, more rapidly, and handy for mounting, dismounting, inspection, and upkeep.

Application of four-row tapered roller bearings

4-row tapered roller bearings are used throughout the world for rolling mill bearing arrangements where rolling speeds are gradual to average. They are mostly utilised in the doing work roll necks of sizzling or chilly rolling mills and roll necks of cogging mills. They generally clearance fit with roll necks to currently being mounted and dismounted conveniently.
