Retén sc4
El perfil SC4 es un retén de simple labio especial para sistemas de suspensión de motocicletas y bicicletas, compuesto por una única jaula de metal con un revestimiento de goma y un labio de sellado primario, con muelle.
CHARACTERISTICS
- Good static sealing.
- Good compensation for thermal expansion
- Reduced risk of corrosion.
- Sealing for low- and high-viscosity fluids
- Modern primary sealing lip with low radial forces
- Sealing lip designed for linear movements.
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.
