Dynapac 4700939265 Planet Gear Seal

The Dynapac 4700939265 is a planet gear seal engineered for the final drive planetary assemblies of Dynapac vibratory rollers. It functions as a critical sealing barrier at mating surfaces to contain gear oil and prevent ingress of dirt, water, and abrasive particles. This component is listed in the parts catalogues for models CA252D, CA260D, CA262PD, CA300D, and CA602D. The seal is a cassette-style design typical for heavy-duty compaction equipment drivetrains. It is supplied as an OEM replacement part under the Dynapac, Atlas Copco, Sandvik, and Epiroc brand networks sharing the identical part number.
