A NILOS-Ring that seals the outer roller bearing ring is described as a type AV. Description: An “externally-sealing” NILOS-Ring for a single-row 6410 AV deep groove ball bearing is described as type “6410 AV”.	In design work the types of NILOS-Rings that seal the inner roller bearing ring should be used if at all possible. For preference, use the corresponding NILOS-Rings of type JV. Description: An “internally-sealing“ NILOS-Ring for a single-row 6410 deep groove ball bearing is described as  type “6410 JV”.
