Product application

In hydraulic cylinders the most commonly used guides are guide rings and guide strips. They accommodate radial loads of forces acting on the cylinder assembly and guide the rod in the cylinder head as well as the piston in the cylinder bore. Our hydraulic cylinder guide rings are widely used in engineering machineries, such as Loaders, Excavators, Fork Lift Trucks…
