INA Bearing AXK3047-A Category: INA Bearing > Roller Bearings > Axial needle roller and cage assemblies,Bearing arrangements with axial needle roller and cage assemblies have a high axial load carrying capacity, are extremely rigid and can support axial forces in one direction.
Bearing arrangements with axial needle roller and cage assemblies are particularly suitable where:
high axial forces occur in one direction and no radial loads are present
the load carrying capacity of comparable axial deep groove ball bearings is no longer adequate and the very high axial load carrying capacity of axial cylindrical roller bearings is not yet necessary.
the axial space available is only extremely small.
the bearing parts can or must be mounted separately.
INA Bearing AXK3047-A Axial needle roller and cage assemblies with axial bearing washers
Axial needle roller and cage assemblies AXK comprise geometrically stable plastic or metal cages fitted with a large number of needle rollers.
For particularly low axial section heights, axial needle roller and cage assemblies can be integrated directly in the adjacent construction. The running surfaces for the rolling elements must therefore be produced as rolling bearing raceways.
The axial needle roller and cage assemblies are generally combined with axial bearing washers. This is appropriate if, for example, high speeds occur and the bearing washers must therefore be precisely centred or the running surfaces for the rolling elements cannot be configured as a rolling bearing raceway.
Needle roller and cage assemblies are single or double-row units comprising cages and needle rollers. As their radial design height only corresponds with the diameter of the needle rollers, needle roller and cage assemblies can be used to realize bearings with a minimal radial design envelope. They have high load carrying capacity, are suitable for high speeds and are particularly easy to fit. If the raceways are produced to high geometrical accuracy, bearing arrangements with high run out accuracy can be achieved.
The radial internal clearance can be influenced by the needle roller sort as well as by the shaft and housing tolerances. Needle roller and cage assemblies require a hardened and ground raceway on the shaft and in the housing.
Axial needle roller bearings
INA Bearing AXK3047-A Axial needle roller bearings are construction units consisting of axial needle roller and cage assembles and thrust bearing washers with centering spigots. They can be combined with drawn cup needle roller bearings with open ends, drawn cup needle roller bearings with closed ends and needle roller bearings. The running surface for the needle roller and cage assembly must be hardened and ground.
