Radial Oil Seals TRP are seals with a completely rubber-covered outer diameter. This type of seal is designed for pressures up to 0.5 MPa. In order to avoid "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. The outer diameter can be provided flat or waved.
