V-ring seal VA

rotaryelastomerNBR

Description The V-ring VA is an axial, single-acting sealing ring designed for non-pressurized shaft and bearing sealing. Unlike radial oil seals, the V-ring seals against the axially oriented front face. When installed, the V-ring VA is expanded onto the shaft inner diameter to ensure an interference fit. It is suitable for high-speed rotation and provides flexibility and adaptability. It protects against dust and splashing water. Standard elastomer materials are NBR with ozone resistance and FKM; other materials are available on request.

Fields of application

• Static
• Dynamic
