China Factory for Main Spindle Bearing - BK2520 Drawn cup needle roller bearings – CWL Detail:

The drawn cup of hardened steel and the needle roller and cage assembly of these bearings form a non­separable unit.

The outer ring of drawn cup needle roller bearing is punched with the high-quality steel sheet. The outer ring has thin wall.

The drawn cup needle roller bearing has the characteristics of small radial section area, large load carrying capacity, less inertia and economic manufacture. It is suitable for small section height, or when the housing bore isn’t used for raceway, this type is recommended to use. The bearing is assembled into the housing bore under a certain pressure without further axial location.

The drawn cup needle roller bearing generally takes its shaft diameter as the internal raceway.
The drawn cup needle roller bearing has two structures-with retainer and with full of needles. They are divided into opened type and close-end type. The structure with retainer has the single seal ring and double seal ring. The structure with full of needles has a large load carrying capacity.
