Agricultural machinery is constantly exposed to dirt, moisture, chemicals, and intense mechanical forces. To ensure performance and reliability, hydraulic systems must remain tightly sealed against contaminants and pressure loss. This is where multi-component COMBI radial shaft seals excel.

These advanced seals consist of a primary lip to retain fluids and secondary elements such as dust lips or spring-loaded designs to exclude external elements. The combination enhances both sealing capacity and system longevity. In harsh field environments, this dual-action design becomes essential for preserving hydraulic performance.

COMBI seals are particularly effective for hydraulic pumps, motors, and cylinders used in tractors, harvesters, and sprayers. Their multi-material structure often includes rubber, PTFE, and metal inserts that resist chemical degradation and maintain elasticity in fluctuating temperatures. The result is a seal that delivers consistent performance even after extended exposure to fertilizers, oils, and UV radiation.

Moreover, these seals are engineered to accommodate shaft misalignment, vibration, and high-pressure pulses—common challenges in agricultural operations. By reducing wear on contact surfaces and maintaining lubricant integrity, COMBI seals minimize maintenance frequency and extend equipment life.

Adopting COMBI radial shaft seals means fewer hydraulic failures, reduced oil consumption, and higher field productivity. For modern agricultural machinery, this is no longer optional but a necessity.
