  • Publication number: 20230383812
    Abstract: The present disclosure is related to a dirt ingress seal (100) for shock absorbers and front forks. The dirt ingress seal comprising a first lip (102a) that isolates the internal space of the seal (100) from the atmosphere and external environment; first ribs (105a) formed on the inner side of the circumferential surface of the dirt ingress seal (100), the first ribs (105a) formed near the first lip (102a); a second lip (102b) provided on the inner circumferential portion near the central region of the dirt ingress seal (100); second ribs (105b) defining cavities; and cavities defined by the first ribs (105a). The cavities are configured to arrest and trap mud, dust, dirt, and particulate matter entering the sealed zone and preventing further ingress of abrasive particles into the seal zone.
