Rotary hydraulic feed-through solutions delivered as complete assemblies by ST-Koneistus
ST-Koneistus manufactures customized, customer-specific rotary hydraulic feed-through solutions for machine and equipment manufacturers. These are widely used in applications such as excavator rototilts as well as numerous other rotating hydraulic interfaces.
A rotary hydraulic feed-through enables hydraulic oil to flow through a rotating connection, allowing the equipment to rotate freely without hoses twisting or tangling. At the same time, the component directs oil precisely to different hydraulic circuits even during continuous rotation.
The manufacturing of rotary feed-throughs is among the most demanding areas in hydraulic component production. The precise alignment of multiple internal flow channels, tight tolerances, and reliable sealing require both high-level machining expertise and careful assembly.
A high-quality rotary feed-through helps machine manufacturers improve equipment reliability and reduce the risk of operational disruptions.
