Mounting bellows

Notice

Damage due to ingress of dust and moisture

Moisture and fine dust in the immediate vicinity can get into the electric cylinder or bellows during operation. This can lead to damage to the product. If protection class IP65 is required, the electric cylinder and bellows must be connected with pneumatic hoses that prevent ingress through pressure equalization.

  • Connect the pneumatic hose to the connector of the bellows and route it outside the process chamber
  • Replace the pressure compensation element on the electric cylinder with a pneumatic connector. Connect the connector to a pneumatic hose and route it outside the process chamber
Mounting bellows 1:

Tools required (not included in the scope of delivery)

Mounting bellows 2:
►Place the O-ring [1] over the flange of the electric cylinder
►Push the O-ring [1] further towards the electric cylinder to the stop

Notice

Damage to the mechanics of the electric cylinder

Transverse forces and torques can damage the ball screw and integrated anti-twist protection of the electric cylinder.

  • Avoid transverse forces and torques during assembly
  • In any case, use tools to hold the spindle in position, such as a wrench

WARNING

Risk of injury due to altered zero position

The piston rod extension changes the previously set zero position of the spindle. Failure to do so may result in serious injury and damage to the electric cylinder.

  • Set the new software end positions in your project
Mounting bellows 3:

Second 15 mm open-end wrench required

An additional 15 mm open-end wrench is required to lock the spindle end of the electric cylinder when screwing on the spindle extension.

Mounting bellows 4:
►Screw the spindle extension [1] onto the spindle end of the electric cylinder
►Tighten the spindle extension [1] with a 15 mm open-end wrench to a tightening torque of 20 Nm and secure with a threadlocker

Notice

Damage due to improper assembly

If the bellows are not mounted properly, moisture and dirt can get onto the spindle of the electric cylinder. The tightness of the bellows is only guaranteed if it is correctly seated.

  • Check that the bellows are seated correctly
Mounting bellows 5:
►Attach the bellows [2] to the flange fastening [1]
►For a positive connection, the end of the bellows [2] must be inserted into the groove of the flange fastening [1]
Mounting bellows 6:
►Slide the bellows and flange fastening [2] onto the flange of the electric cylinder [1]
Mounting bellows 7:
►Use a 2 mm hex key to tighten the two lateral set screws [1] of the flange fastening to a tightening torque of 1 Nm and secure with a threadlocker
►Screw the pneumatic push-in fitting [2] into the flange fastening with a tightening torque of 3 Nm
Mounting bellows 8:
►Pull the front end of the bellows [1] over the spindle extension [2] and bring it into position
Mounting bellows 9:
►Place the hose clamp [1] over the front end of the bellows and tighten with suitable pliers
