SKF 78X90X17DOCR60 — Metal face seal (Duo-Cone / mud seal)
SKF · Seals & Gaskets · Metal Face Seals (Duo-Cone)
SKF 78X90X17DOCR60 metal face seal (duo-cone / mud seal). Rotary metal face seal — two lapped cast-alloy sealing rings loaded together by opposed elastomer torics. Designed to seal shafts running in gritty, abrasive slurry conditions where a lip seal would be immediately destroyed. Standard on track-drive final-drives on tracked excavators, dozers and marine deck-machinery where dredge slurry, cement wash or seawater is present. Nominal shaft speed to 4 m/s. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options.
