The Axial Seal (OEM Part No. 0666800704) is a replacement sealing component used in the feed and hose drum assemblies of Epiroc / Atlas Copco underground and surface drilling equipment. It provides axial sealing around rotating or moving components, helping retain lubricant and reduce the entry of dust, dirt and other contaminants into the assembly. The 0666800704 Axial Seal is suitable for routine maintenance and replacement when the original seal becomes worn, hardened, cracked or damaged. Proper sealing helps protect associated bearings and rotating components and supports reliable operation of the feed and hose drum system. Epiroc documentation identifies 0666800704 specifically as an AXIAL SEAL.
