Type TRU
Trelleborg Sealing Solutions Type TRU is a seal with completely rubber covered outer diameter. This type of seal is designed with an extended metallic support of the diaphragm that allows pressures up to 0.5 MPa. In order to avoid a "pop-out" of the seal, we suggest to fit an axial retainer (e.g. circlip, shoulder, etc.). The additional dust lip protects the main sealing lip against dust and other fine solid contaminants and therefore this type is recommended for use in polluted environments. To achieve a long lifetime a suitable lubricant between the two sealing lips should be applied.

Material Information for the product(s) on this page
4V012
Colour:
Brown
Basic Material:
FKM/metal
Commercial Description:
This is an FKM elastomer bonded to a metal case. FKM is often used in high-temperature applications, but usually there is a trade-off in performance at very low temperatures.
4N011
Colour:
Black
Basic Material:
NBR/metal
Commercial Description:
A standard choice for radial oil seals, this is an NBR elastomer bonded to a carbon steel case. This combination is a good balance of economical performance for applications with relatively mild temperatures.
