NILOS-RING AV

The gap seal for demanding applications

The NILOS-RING in both the AV and JV versions is a contact seal in the standard version. A non-contacting gap seal in the µ range is only created after a certain running-in phase by grinding into the bearing ring. The standard version of the NILOS-RING types can be used up to a circumferential speed of 6 m/s.
However, this speed range is not sufficient for many applications. But even here you do not have to do without the usual reliability of the NILOS-RING as a sealing element.

If it is possible to run in below 6 m/s, the sealing edge will have ground in after some time and higher speeds can then be driven without hesitation. If running-in is not possible, NILOS-RINGS with reduced preload or minus preload are used. In this case, please specify the speed when ordering. We will then determine the appropriate preload to suit the application and speed. JV types are preferable for circumferential speeds from 15 m/s.

Type AV and ZAV for rolling bearings

The NILOS-RING AV and JV are the most commonly used designs. They can be used as a standard version up to a circumferential speed of 6 m/s; higher circumferential speeds must be specified when ordering.

For Z and RS bearings ZAV, ZJV
Bearings already fitted with shields or sealing washers are sealed using NILOS-RINGS with different dimensions so that the seal clamped in the bearing is completely encapsulated by the NILOS-RING. NILOS-RINGS are particularly necessary here if dirt can penetrate the bearing or if condensation forms.

Type AV:
The NILOS-RING that seals on the outer rolling bearing ring is designated as type AV.
Designation:
E.g. the NILOS-RING abbreviation 6410 AV is used to designate an externally sealing NILOS-RING for a single row deep groove ball bearing 6410.

Type ZAV:
The NILOS-RING that seals on the outer rolling bearing ring is designated as type ZAV.
Designation:
E.g. the NILOS-RING abbreviation 6205 ZAV is used to designate an externally sealing NILOS-RING for a single row deep groove ball bearing 6205 with shields or sealing washers.

Type AV for tapered roller bearings

The NILOS-RING AV is manufactured for the bearing sides shown in the sketch. The dimensions of the sealing edge are significantly different from those of the other designs due to the different widths between the inner and outer bearing rings. It is dimensioned in such a way that it still makes secure contact with the rolling bearing ring and thus provides a reliable seal in all cases.

Type AV:
The NILOS-RING that seals on the outer tapered roller bearing is designated as type AV.
Designation:
E.g. the NILOS-RING abbreviation 302 07 AV is used to designate an externally sealing NILOS-RING for a single-row tapered roller bearing 302 07.
