Retén TC

El perfil TC es un retén de doble labio compuesto de una única jaula de metal con un revestimiento de goma, un labio de sellado primario con muelle integrado y un labio guardapolvo que actúa de protector contra la acumulación de suciedad desde el exterior.

CHARACTERISTICS 
  • Está bien sellado.
  • Compensation of different thermal expansion.
  • Reduced risk of fretting corrosion.
  • A higher surface roughness of the bore is allowed.
  • Sellado para fluidos de baja y alta viscosidad.
  • Labio de sellado primario moderno con fuerzas radiales bajas.
  • Protección contra contaminantes no deseados del aire.

See our gnstallation guide for oil seals to perform a correct installation of the seal.

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.
