Nilos Rings

USN is a ZILLER distributor, who produces the unique NILOS RINGS. This metallically seal NILOS RING for bearings is fixed on a side of a bearing to avoid any contamination by solid particles. Every bearing has is own NILOS RING dimension. They are minly use in agriculture, road work equipment, automotives and general industries.

Shapes AV and JV

These two types of NILOS-Rings cover the majority of configurations used. The standard types of NILOS-Rings can be used for peripheral rotating speeds of up to 6 m/s; higher speeds must quoted without fail when ordering.



Shapes ZAV and ZJV

For Z and RS bearings ZAV, ZJV

The sealing of bearings that have already been provided with shields or seals is done by NILOS-Rings of other dimensions so that the seal clamped into the bearing is fully encapsulated by the NILOS-Ring. NILOS-Rings are required in particular in such cases if dirt can penetrate up to the bearing or if condensation is formed.

Shapes for taper roller bearings type AV, JV and AK

For taper roller bearings AV, JV, AK

The two forms of NILOS-Ring, the AV and the JV, are produced for the bearing sides shown in the illustration. The dimensions of the sealing edge are significantly different from those for other forms due to the difference in width between the inner and outer bearing rings. They are dimensioned to guarantee to be always  in place on the roller bearing ring and thus ensure that proper sealing is achieved in all cases.

Shapes LSTO and SLTL

Steel disk seal LSTO

Sealing package comprising of steel disks are ready for installation and capable of handling thrust loads. The sealing works on a non-contact basis and can follow axial movements of the roller bearing rings to 0.3 mm without any jamming of the disc.

Type LST-L steel disk seal

The type LST-L ring is a further development of the type LSTO NILOS ring. By means of an additional Viton gasket, a considerable sealing effect is achieved when in contact with liquids.
