Guiding rings
Hydraulic guiding rings are components used in hydraulic or pneumatic systems to ensure the precision and stability of translational and rotational movements. They are, therefore, crucial for sealing systems. Primarily employed in cylinders, they can be found in applications such as machine tools, presses, robots, lifting equipment, and material handling.
Most Guiding rings today are non-metallic, offering excellent friction coefficients and wear resistance. They can also accommodate angular movements. Guiding rings contribute to operational cost optimization through improved energy efficiency and reduced machine downtime. Typically assembled in a closed groove, they are easy to install and replace.
