Needle roller bearing

Needle bearing

Drawn cup needle roller bearing

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.
