Zárt fémházas szimering

TA is reinforced metal cased radial lip seals. The supplementary metal inner ring provides a superior stiffness. This type is not recommended for use in heavy polluted environments. As the static sealing between housing and metallic shell is limited, low viscosity media can “creep“. Better performance can be achieved with epoxy based resin O.D. coating. This special treatment is on request.

spring steel
MediaMineral oils, Greases
Temperature-35°C / +100 °C
Pressure≤0,5 bar
Speed12 m/s

Product advantages

  • superior radial stiffness, especially for very large diameters
  • very good fitting stability avoiding pop-out of the seal
  • modern lip design provides low radial forces
  • cost effective for expensive elastomer materials
  • suitable for use in combination with axial seal (V-Ring)

Application

The TA is particularly suitable for large dimensions as well as difficult installation conditions and severe operating conditions. For transmission systems (e.g. gearboxes), pumps, electrical motors, machinery industry (e.g. tool machines), heavy engineering applications (e.g. mills in steel industry).

Installation

Suitable tool should be used for installation. It is recommended that the installation housing is designed to provide the rotary shaft seal with axial support.
