V-ring seals

The V-ring is an axial elastomer seal that is mounted stretched over the shaft, rotates with it, and rests its lip against a perpendicular face, either that of a housing or another component. It acts as a deflector: it prevents the ingress of dust, water and particles and helps retain lubricant. It is used as primary protection in contaminated environments or as a secondary seal in front of a radial shaft seal.

SKF part numbers combine a size number, the type abbreviation and a material letter. In 100 VA R, 100 VS R, 110 VA V or 100 VS V, VA and VS are different design types, the number corresponds to the size according to the shaft diameter, and the final letter distinguishes the seal elastomer. Since the same size is manufactured in several types and materials, the complete part number is what defines the part.

To select, consider the shaft diameter, peripheral speed, temperature, type of contaminant and the condition of the counterface, which must be flat, smooth and perpendicular to the shaft. At high speeds, it is advisable to axially secure the V-ring so that it does not open due to centrifugal force. It is common in electric motors, gearboxes, pumps, fans, belt conveyors and agricultural machinery.

In this subcategory we work with SKF. To request a quote, send us the complete part number or the shaft diameter, the application type and the operating temperature via WhatsApp. If you are replacing a seal from another brand, send us the designation and we will indicate the equivalent.
