BD Evolution Secondary Sealing Lip Compact Rod Seal
The BD type rod seal is a compact seal with a secondary sealing lip and an evolution seal. The additional sealing edge results in a larger lubricant deposit in the sealing gap. This largely prevents increased wear and achieves longer service life. in addition, the need for a complex tandem arrangement may be eliminated by the second sealing lip in some cases. Hydraulic cylinders in earth-moving machines are typical applications for this seal. They may involve pressure peaks of up to 1000 bar.
