Concentricity

The NILOS RING must be centered along with the bearing, being:

AV Ring – on the AXIS
JV Ring – on the BUSHING

imag4

Fixing the Ring

The NILOS RING must be fixed firmly against the bearing in order to guarantee the formation of a micro groove and to keep it from slipping, as shown in drawing 4, being:

AV Ring – fixed on the inner ring of the bearing.
JV Ring – fixed on the outer ring of the bearing.

Spring Effect

In the first hours of operation, the NILOS RING acts like a spring plate, exerting a certain pressure on the internal ring (JV) or external ring (AV) of the bearing.
