Trunnion Mount Hydraulic Cylinder

Trunnion Mount Hydraulic Cylinder/Excavator stick cylinder/Crane variable amplitude oil cylinder A trunnion mount hydraulic cylinder features dual pivot mounts for articulated motion, allowing ±10-15° angular movement under load. It converts hydraulic pressure into linear force (typically 50-500T) while handling radial/axial loads. Key Applications: Excavator arm/boom cylinders Crane luffing mechanisms Rolling mill presses Ship steering systems Advantages:Dual trunnions distribute stress better than single mountsEliminates need for additional support bearingsOptional flange/sleeve designs for varied loads Design Notes:Calculate bending moments at max swing angleUse bronze-bushed trunnions for wear resistancePair with self-lubricating bearings Ideal for dynamic misalignment applications, these cylinders operate at 210-350bar (up to 500bar in heavy-duty versions) with extended service life.
