SEAL SAN
The SA 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 with an integrated spring.
CHARACTERISTICS
- Good radial stiffness, particularly suitable for large diameters
- High installation stability to prevent seal displacement or push-out
- Economical option for applications involving high-cost elastomers
- Modern primary sealing lip with low radial forces
- Suitable for use in combination with axial seals (V-ring, RE)
- Reinforced with an inner metal case for increased structural stiffness
- Primary sealing lip designed for pressures up to 5 bar
See our gInstallation 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.
