INA from Schaeffler radial insert ball bearings with rubber interliners are on the shaft using an eccentric locking collar. The outer ring is encased in a thick-walled NBR interliner which absorbs vibrations and shocks. The interliners have either a spherical or cylindrical outside surface. The P seal is two zinc-coated sheet steel washers with intermediate NBR part, seal lip axially preloaded.
To protect the seal lip from mechanical damage, the outer sheet steel washer extends a considerable distance down towards the bearing inner ring.
Used in narrow radial insert ball bearings with inner ring extended on one side.
