When installing the Ratio-Clamp®, the round rod to be clamped must fulfil the minimum requirements as shown in the drawing. Especially the diameter tolerance f7 and the minimum hardness of 48 HRC must absolutely be observed.
Since the sealing systems used in Ratio-Clamps® are designed accordingly, a honed rod is recommended for this type of application.
Minimum requirements for the rod to be clamped
Functional rods are chrome-plated rods with freely configurable piston rod ends and can directly be removed in HäKo.
These piston rods can be configured in steps of 1 mm via the stroke, which corresponds to the length to be moved.
Additionally, the functional rod can be lengthened on both sides to make them fit the installation requirements.
