TECHNICAL DESCRIPTION - PRODUCT FUNCTION
ZH2RT is double-acting hydraulic cylinder with regulated damping in the end positions. Linear hydraulic motor is basically an element that converts the pressure energy to the mechanical energy – to the axial power of the piston rod in both directions. They have – by their construction – no special demands for service and maintenance, but it is necessary to obey the service and technical conditions for perfect and secure function of the motor. This type is equipped with regulated damping, that acts as a restriction of the oil flow in the last part of the stroke, which slows down the movement of the piston rod, reducing shocks that would otherwise be transferred from the hydraulic cylinder to the structure. Damping is regulated, so it is possible to set the speed at which the cylinder will move the last part of the stroke. For demanding work conditions with high workcycle count we recommend non-welded alternative ISO6022, or atypical if required.
Cylinders are normally made with „eye-eye“ mounting, but they can be equipped with flanges, pivots, feet, or atypical mounting. All informations on mounting and dimensions can be found in the product catalog.
With requests about other (nonstadard) types of mounting please contact our technicans via phone or contact form.
