Thrust roller bearings

Thrust roller bearings

Thrust roller bearings can accommodate joint axial and radial loads(mainly axial loads), but the radial loading doesn't surpass the axial loading 55. Compare with other thrust roller bearings, this kind of bearings friction factor is low, rotational speed is high, and has aligning function.

The main type of thrust roller bearings are as follows:
cylindrical roller thrust bearings
tapered roller thurst bearings
needle roller thrust bearings
spherical roller thrust bearings

29000 series bearing rollers are asymmetrical spherical rollers, can reduce the roller and roller conveyer's relative sliding when are working, besides, this kind of bearing's rollers are long, diameter is big, the quantity of rollers are large, the loading capacity is high, and usually uses the oil lubrication, some low speed bearings use fat lubrication. This kind of bearings are the first selection.

80000 series cylindrical roller thrust bearings, 90000 series tapered roller thrust bearings and AXK series needle roller thrust bearings can bear the axial loading in one direction, those kind of bearings axial loading capacity are much large than spherical roller thrust bearings, besides, the rigidity is also large, take small space of the axial.
