Unrestricted Power: Deublin 2200-000-003 for Heavy Yarder Drives
When you are operating the largest yarders in the NZ bush, you need a rotary union that can deliver massive air or hydraulic volume without hesitation. The Deublin 2200-000-003 (2200 series) features a full 1-1/2″ NPT flow path, engineered specifically to prevent pressure drops in the main drive clutches of high-production haulers. In cable logging, where cycle times are everything, the 2200 series ensures your winch responds instantly to the operator’s command.
Built to withstand the brutal vibration and heavy “shock loads” of a working landing, this union features a self-supported design with dual-row ball bearings for maximum stability. The specialized seals are micro-lapped to ensure a leak-proof performance under the intense duty cycles of a skyline operation. By installing a genuine Deublin 2200 series union, you are investing in a component that is proven to handle the massive torque and fluid demands of the world’s most powerful yarders
Heavy Tower & Swing Yarder Applications
