What is thrust needle bearing?

Thrust needle bearing is consist of a set of tray ring gaskets combined with retainer with roller bearings.The stand leads and holds many rolling elements.The thrust needle bearings or thrust-cylindrical roller bearings can support the bearings with the axial directional load and so the can be used as the bearings with good rigidity and minium axial occupied spaces.

If the surface of the adjacent parts can be used as a tray for the rolling needles and the holding stand assembly should be recommended when the support space is big enough so that a small axial cross sectional altitude can be achieved.Same effectiveness can be ensured in different cases when combined with the relatively thicker ring gaskets of LS,GS,WS,ZS series.The applicable gaskets series of AS,LS,GS,WS,ZS are optional and will be ordered sparately by the buyers.

Thrust needle bearing is units comprising axial needle rollers and cage assemblies and axial bearing washers with a centring spigot. thrust needle bearing is able to accommodate heavy axial loads. They are insensitive to shock loads and provide a high degree of bearing units stiffness within a minimum axial space. They represent unidirectional bearings and can accommodate axial loads acting in one direction only.

Using thrust needle bearing, it is possible to make compact bearing units. They will take up no more space than a conventional thrust washer, when the faces of adjacent machine components can serve as raceways for a set of thrust needle rollers with cage. In the cases when faces of adjacent machine components cannot serve as raceways, a set of thrust needle rollers with cage can be combined with washers of various designs.
