6203ZJV Nilos Ring for 6203Z Series Bearings 20.2x40x2mm

Nilos ZJV Sealing Rings: A Nilos ring that seals the inner roller bearing ring is described as a ZJV type. They are used to provide additional sealing of bearings that already have shields or seals. A Nilos ring of suitable dimensions can be installed so that the Nilos ring fully encloses the existing seal in the bearing.
Nilos rings are required in particular installations where excess dirt or debris may be present that could penetrate up to the bearing, if some further mechanical protection is required or if condensation is formed.
Sealing is produced by placing the sealing edge of the Nilos ring under light pressure at the inner bearing ring so that it rubs to a greater or lesser depth into the hardened roller bearing ring. The fine labyrinth that is produced as a result prevents the leakage of grease and the penetration of dirt into the bearing.
Note: If sealing is required around the outer raceway then a ZAV type Nilos ring should be used. Benefits: Provides mechanical protection to existing bearing seals, forms its own labyrinth seal in use and allows condensation build-up to vent to the atmosphere.
