Nilos LSTO ring 20x47

Nilos LSTO ring 20x47 Inside diameter = 20 mm. Outside diameter = 47 mm. WA = 41 mm. WJ = 26 mm. h = 4 mm. Nilos-Rings of type LSTO are non-contact, grease-filled labyrinth seals that are ready for installation for the relevant shaft and casing diameters. They should be used above all if grase-lubricated bearings are subjected to exceptionally large amounts of dirt, e.g. Contruction machinery, Agricultural machinery, Woodworking machinery and Conveyor rollers, etc. These sealing elements fullfil almost ideally the requirements for a seal for a roller bearing; frictional losses and heating up of the bearing are insignificantly small, while the leakage of lubricant and the penetration of dirt are prevented.
