Retén TA
El perfil TA es un retén radial, para sellado de eje, compuesto por una única jaula metálica exterior, con una jaula interior adicional, que proporciona mayor rigidez estructural, un labio primario de estanqueidad con muelle integrado y un labio guardapolvo adicional.
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
- Auxiliary dust lip designed to block airborne contamination
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.
