NILOS Nilos-ring 25X52 LSTO steel disk seal

Nilos steel disk seals of type LSTO are non-contact, grease-filled labyrinth seals. The LSTO-seals should be used above all if grase-lubricated bearings are subjected to exceptionally large amounts of dirt. Nilos LSTO-rings are suitable for each type of bearings with the same inner- and outerdimensions.
