【WOMA】8T-5040 – 44.68mm Outer Diameter Lip Seal Precision-engineered sealing for demanding jobsites

The 8T-5040 outer diameter lip seal, measuring 44.68mm, represents a pinnacle of precision-engineered sealing solutions tailored for the most demanding construction and heavy-equipment job sites. Manufactured to exacting tolerances, this high-grade component ensures robust protection against contaminants, lubricant loss, and premature wear, thereby extending the service intervals and operational lifespan of critical machinery. Its advanced lip geometry and durable material composition provide a reliable barrier in high-vibration, high-debris environments, making it an essential maintenance item for fleet managers and equipment operators who prioritize uptime and performance. The seal is broadly compatible with a diverse range of Caterpillar equipment, ensuring versatile application across multiple machine categories. For cold planers, it directly fits the PM-465, PM-565, and PM-565B models, supporting road-milling operations with consistent sealing integrity. In dozer applications, it serves the 4S, 4P, and 4A series, safeguarding final drives and track components. The seal is equally suitable for reclaimers and stabilizers, including the RM-350B and RM-350, where it helps maintain rotor drive systems under heavy loads. For backhoe loaders, it offers a direct replacement for the 416 and 428 models, reducing downtime during trenching and loading tasks. Track skidder operators will find it compatible with the D4HTSK II and D4HTSK III, ensuring reliable performance in logging and site-prep work. Additionally, it meets the sealing requirements for the 4-series ripper attachments, providing durability in extreme breakout-force conditions.
