车身与底盘系统 - 工业百科
The 9W6699 floating seal duo-cone assembly is engineered for final drive and travel reduction systems on Caterpillar hydraulic excavators. The metal face seal utilizes 100Cr6 bearing steel rings hardened to 58-62 HRC, paired with NBR 60 Shore A elastomer toric rings rated 60-65 Shore A. This metal-to-metal dynamic sealing interface retains lubricating oil while excluding abrasive contaminants in severe undercarriage environments. Designed as a direct replacement for Caterpillar OEM part numbers 9W6699 and 9W-6699, the assembly withstands high rotational speeds and axial loads typical of 20-25 metric ton class excavators. Service life targets 3000-5000 operating hours under standard conditions. Installation requires precise housing alignment and recommended lubrication procedures to prevent premature face wear.
