Retén SGW
El perfil SGW es un retén de labio simple, compuesto de una única jaula de metal, con un revestimiento de goma y un labio de sellado primario con muelle integrado. El labio de estanqueidad tiene estrías con un sentido de rotación bidireccional, para seguir el mismo giro del eje y controlar la expulsión de lubricante. Dispone de un estriado en el exterior para facilitar el montaje.
- Good static sealing.
- Compensation of different thermal expansion.
- Reduced risk of fretting corrosion.
- A higher surface roughness of the bore is allowed.
- Installation in split housings.
- Knurled exterior for ease of assembly.
- Labio de sellado con estrías con un sentido de rotación bidireccional.
Please refer to our oil seal installation guide for proper oil seal installation.

TOLERANCE FOR THE INNER DIAMETER OF THE SEAL
When not under pressure, the inside diameter of the sealing lip is always smaller than the shaft diameter. The difference between the two dimensions is known as interference or pre-fitting. Depending on the shaft size, the sealing lip diameter is estimated to be between 0.8 mm and 3.5 mm smaller. It will depend on the setting chosen by each manufacturer.
