Needle Roller Bearing With Machined Rings Without Flanges NAO 20x35x17

Needle roller bearings without flanges are completely separable, i.e. the outer ring, the needle roller and cage assembly and the inner ring can all be mounted separately. In many applications, this makes mounting a great deal easier. The needle roller and cage assembly can either be mounted together with the outer ring or with the shaft or inner ring, depending on the arrangement design. It can also be inserted between the outer ring and shaft or inner ring as the final step. However, needle roller and cage assemblies and bearing outer rings must always be kept together as supplied.

The needle roller bearings without flanges are available as single row or double row bearings. Double row bearings have two needle roller and cage assemblies arranged adjacent to each other. They have an annular groove and a lubrication hole in the outer ring to enable efficient lubrication.

To provide efficient lubrication for needle roller bearings with an inner ring, we supplies some bearings with one lubrication hole in the inner ring. The cage of needle roller bearings without flanges must be axially guided by fine turned and burr-free surfaces on adjacent machine components.
