Axial Thrust Needle Roller Bearing And Cage Assemblies AXK1730 2AS 17*30*4mm

Axial thrust needle roller bearing AXK1730+2AS

Needle roller bearing /cam follower is composed of a stud used as the tray of a group of rollers and a thick wall outer ring .The shoulder of the stud and the surface retaining ring on the stud form the guiding faces on the two sides of the outer ring.When the curve rollers are running on the plain tray or cam wheel,the inner stress on the rollers will increase due to the deformation of the outer ring.

Products Information

Thrust needle and retainer assembly are comosed 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.

Axial (Thrust) needle roller bearings are units comprising axial needle rollers and cage assemblies and axial bearing washers with a centring spigot. Axial (Thrust) needle roller bearings are 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.

Materials

Material for needle roller is GCr15 bearing steel, quench-hardening HRC60---65.
Material for inner and outer races is GCr15 bearing steel, quench-hardening HRC61---65.
Material for cages is quality low-carbon steel or reinforced nylon.
