Roller Needle Bearing K HK NA NX NKI NK HFL NAV NKXR NKIA AXK-2Z BK HF Full needle series Rollers
Description of Roller Needle Bearing K HK NA NX NKI NK HFL NAV NKXR NKIA AXK-2Z BK HF Full needle series Rollers
1.Overview: Drawn cup needle roller bearings ,needle roller bearing support radial loads and reduce friction between rotating components, with a drawn outer shell serving as a raceway for the rollers. The low cross section of the drawn cup bearing provides high load-carrying capability with minimum required space. Drawn cup bearings are easily installed with a press fit in the housing.
2.Advantages:needle roller bearing
- Smaller cross-section leading to greated rigidity,higher load-carrying capacity & lower inertia of the needle roller bearings help size and weight reductions in machinery.
- Though they are less wide,their load carrying capacity is high and is most suitable for applications where the load is high & the radial space is less.
- Needle roller bearings,which are designed to withstand oscillation can operate under severe conditions & interchange with sliding bearings
3.Applications:needle roller bearing
- Transmissions,transfer cases,engines & valve trains
-Steering and braking systems
- Axle support
-Outboard engines
3.Expanded Options
- Assemblies with bearings
- Engineered polymer cages
- Bearings with one or two seals
-Closed end bearings
- Oil holes
-Drawn sleeve
4.Needle roller bearing specifications & Standards:
-Dimensions:the boundary dimensions of the drawn cup needle roller bearings are in accordance with ISO
-Bore size:Its size is meassured in millimeters.The bore is a hollow cylindrical chamber or barrel shaped where the metal balls are placed.
-Outer ring width:It is the width of the outer ring measured in millimeters.
5.Markets: needle roller bearing or needle bearing for Transmissions, transfer cases, engines, valve trains, steering and braking systems, axle supports,outboard engines, power tools, copiers, fax machines, paper-moving equipment and appliances.
