Power Take-Off (PTO) shafts in tractors are vital for transferring mechanical energy to implements like mowers, tillers, or balers. These components face constant motion, contamination, and high torque, requiring effective sealing to maintain performance. COMBI radial shaft seals are specifically designed for these rugged conditions.

The unique multi-component structure of COMBI seals combines a primary oil-retaining lip with a dirt-exclusion lip, ensuring that lubricants stay in while contaminants remain out. This double-action design is essential in off-road environments where dust, crop residue, and mud are constant threats.

In tractor PTOs, standard seals often fail due to misalignment, shaft deflection, or temperature changes. COMBI seals, however, are engineered with elastomers that maintain flexibility and performance under thermal expansion, ensuring consistent sealing through cycles of heavy load and rest.

Furthermore, COMBI seals help reduce grease leakage, which is not only a maintenance issue but also an environmental concern. Their superior design contributes to longer service intervals, less downtime, and reduced lubricant waste.

With COMBI seals, farmers can trust their PTO systems to operate efficiently and reliably across seasons, protecting both equipment and productivity.
