Retén VB
The VB profile is a radial shaft seal designed for shaft sealing applications. It consists of a single external metal case and a single primary sealing lip without a spring.
CHARACTERISTICS
- Superior radial stiffness, especially for large diameters
- Good assembly stability to prevent rebound effect
- Sealing for high-viscosity fluids
- Primary sealing lip design that ensures low levels of friction and heat generation
See our gnstallation guide for oil seals to perform a correct installation of the seal.

TOLERANCE FOR THE INNER DIAMETER OF THE SEAL
The inner diameter of the sealing lip is always smaller than the shaft diameter. Depending on the shaft size, the sealing lip diameter is generally between 0.8 and 3.5 mm smaller than the shaft diameter.
