V-ring seal VL

rotaryelastomerNBR

Product description The V-ring VL is an axial, single-acting seal for non-pressurized shaft and bearing applications. Unlike radial oil seals, the V-ring seals against the axially oriented front face. For installation the V-ring VL is expanded over the inner diameter to achieve a tight fit on the shaft.

Design and materials The V-ring VL features compact geometry suitable for narrow installation spaces. Standard elastomers: NBR (with ozone resistance) and FKM. Other compounds available on request.

Fields of application

• static
• dynamic
• single-acting
• double-acting
• linear
• rotating
• oscillating

Main use Anti-contaminant shaft outlet seal for grooves with small radial and axial dimensions.

Materials Elastomers (standard: NBR, FKM).

Technical values Materials: NBR / FKM
