Thrust roller bearings
Thrust roller bearings includes self-aligning thrust roller bearings, tapered roller thrust bearings, cylindrical roller thrust bearings and needle roller thrust bearings.
Structures:
1. 29000 type thrust self-aligning roller bearings, this type of bearings can carry both axial and radial load in which mainly is axial load. And it has low friction coefficient and fine self-aligning property. The roller of this bearing is unsymmetrical spherical roller, which can reduce relatively slip between roller and raceway in the operating. Also the long roller has big diameter and much quantity, so the load capacity is high. Generally it adopts oil lubrication, but under low speed circs will be grease lubrication.
NXZ mainly produce the following structures:
2.80000 type thrust cylindrical roller bearings and 90000 type thrust tapered roller bearings, this type can accommodate single-direction axial load, they have much higher axial carrying-capacity than thrust ball bearings; in additional, they have high rigidity and take up smaller space.. The thrust cylindrical roller bearings are applied in operation with low rotation speed; the rotation speed of thrust tapered roller bearings is a little higher than thrust cylindrical roller bearings.
3.350000 type double-directions thrust tapered roller bearings (SKF code), this type can accommodate larger double-direction axial load.
4. TTSV and TTSX type thrust full tapered roller bearings used on pressing-down device of mill, this type is full complement roller, can accommodate larger single-direction axial load.
