NILOS-RINGS Type AV / JV

The standard version of the NILOS-RING – both in AV and JV design – is a contact seal. 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 6 m/s circumferential speed. 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.

NILOS-RINGS Type LSTO

The LSTO-RINGS are a non-contact seal and can be used up to a circumferential speed of 30 m/s.

NILOS-RINGS Type LST-L

Thanks to an integrated Viton disk, circumferential speeds of up to 3 m/s can be achieved with permanently present liquids. If NILOS-RINGS LST-L are intended for applications with non-permanent liquids, the circumferential speed is limited to 1 m/s.
