Description
U-cup hydraulic rod seal BD has two sealing lips and a back up ring that is highly resistant to extrusion. Due to the effect of the two sealing lips, additional lubrication is maintained in the sealing gap, dry friction and wear are greatly prevented, and achieves longer service life.
Under certain conditions, satisfactory sealing performance can only be achieved through two seals installed in the respective grooves one after the other. The additional sealing edge results in a larger lubricant deposit in the sealing gap. In addition, the need for a complex tandem arrangement may be eliminated by the secondary lip in some cases. Hydraulic cylinders in earth-moving machines are typical applications for this seal.
