SLIPPERS  INSTRUCTIONS FOR ASSEMBLY

ASSEMBLY ON THE PISTON IN CLOSED GROOVE AND IN OPEN GROOVE

Assembly in closed groove can be carried out manually, however the use of the appropriate equipment guarantees th integrity of the slipper and time-saving insertion. Assembly in open grooves is suggested for slippers under 30 mm in diameter, unless the HD technicians study other particular solutions.
Correctly carried out introduction blunting and the lubrication of the surfaces make assembly easier.

INSERTION AND RECALIBRATION EQUIPMENT FOR INSTALLATION IN CLOSED GROOVES ON THE PISTON

The expander cone brings the Slipper to the diameter of the piston, or to the edge of the groove when other existing grooves must be passed over.
The thruster expands sector by sector, or more simply, in single logitudinal cutting.
Both the cone and thruster can be made in acetal resin (POM), polyester (PBTF) or polyamide (PA6)

The prolonged extended permanence of the Slipper during installation could determine a permanent increase in diameter; therefore fast installation is advised.
Recalibration of the slipper may be opportune using a sleeve before insertion of the piston in the cylinder.
The sleeve can also permit the passing over of grooves and threads.

INSTALLATION ON THE CYLYNDER IN CLOSED GROOVE

The Slippers seal on the rod can be introduced in the closed groove imposing a reniform deformation on it as indicated.
Open groove installation is advised for rods with a diameter of less then 20 mm

The mono-directional R type Slipper is installed using this method of positioning the seal-step towards the pressure.
