SEAL VA

The VA profile is a radial shaft seal designed for shaft sealing applications. It consists of a single external metal case with an additional inner metal reinforcement, providing increased structural rigidity, and a 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
Springless sealing lip

See our Installation 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.
