Product Characteristics

Tapered roller bearings consist of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. The taper angles allow the bearing to handle a combination of radial and thrust loads. The steeper the cup angle, the greater the ability of the tapered roller bearing to handle thrust loads. They combinations – in single, double and four-row tapered roller bearing configurations. Customized geometries and engineered surfaces can be applied to these tapered roller bearings to further enhance performance in demanding applications.

Product Classification

Structure type of metric and inch single-row, double-row and four-row Tapered Roller Bearings produced by ZQM

1. Single-row Tapered Roller Bearing

This type of bearings can only limit axial displacement of shaft or housing in one direction, and be subject to axial load in one direction. Under the effect of radial load, axial force generated in bearing should be balanced, and two bearings should be used in face to face type or back to back type.

2. Double-row Tapered Roller Bearing

This type of conical bearing can be subject to bidirectional axial load while being subject to radial load. The bidirectional movement of shaft or housing can be limited in the axial windage bound.

3. Four-row Tapered Roller Bearing

The performance of this type of bearing is almost identical with double-row Tapered Roller Bearing, but the bearing can be subject to larger radial load than double-row Tapered Roller Bearing. Its limit speed is a little lower, and it is mainly applied on heavy-duty machine such as rolling mill etc.

4. Multi-seal Double-row, Four-row Tapered Roller Bearing

ZQM offers multi-seal double-row, four-row Tapered Roller Bearing with a long life. The bearing is individuation brand newly designed, and traditional design method of omniseal bearing is changed. A new seal type to seal and prevent dust is adopted. The seal effect is improved, and the seal performance is enhanced. Compared with open bearing, the life span of multi-seal double-row, four-row Tapered Roller Bearing is enhanced by 20%~40%, and the lubricant consumption is reduced by 80%.
