Description

Needle bearing RNA***8

1.Overview:

Drawn cup needle roller bearings 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.Abstract:
(1). The drawn cup needle roller bearings are needle roller bearings with the deep drawn, thin-walled outer ring with either an open end or closed end.
(2). The bearings are characterized by a very low sectional height and high load carrying capacity
(3). The bearings are typically used in applications where the housing bore can not be used as a raceway for a needle roller and cage assembly but where a very compact and ecnomical bearing arrangement is required.
(4). Typically, drawn cup needle roller bearings have a single row of rollers. However, wide sizes incorporate two needle roller and cage assemblies immediately asjacent to each other with a lubrication hole in the outer ring.

3.Advantage:
(1).Low noise
(2).high quality
(3).Low price
(4).A large stock

4.Applications:
- Transmissions,transfer cases,engines & valve trains
-Steering and braking systems
- Axle support
-Outboard engines
