Festo ESBF Series - Mounting the Cylinder; Attachment on Piston Rod

1. Select the motor and motor mounting kit from
Festoèwww.festo.com/catalogue.
When using other motors: observe the critical limits for forces, torques and
velocities.
2. Fasten motor mounting kit, observe instructions èwww.festo.com/sp.
3. Fasten the motor without tension. Support large and heavy motors.
Connect motor cables only on completion of mounting.
7.4 Mounting the Cylinder
High Mechanical Loads on the Mounting Connections
If high rectified torques are applied to the drive system at the same time, this
leads to high mechanical loads at the mounting interfaces.
• The foot mountingHNC, CRHNC should only be used in combination with the
profile mountingEAHF.
• In the case of an inclined or horizontal mounting position with direct mount
ing or flange mountingEAHHV2, the drive system must be additionally sup
ported near the motor mounting.
Requirement
– No collision in the movement space of the attachment component with
mounting and sensor components.
– Sufficient space for reaching and mounting the pressure compensation port.
– Flatness of the mounting surface max. 0.2mm over the stroke length of the
bearing surface.
– No distortion or bending when installing the product.
1. Select mounting attachments èwww.festo.com/catalogue.
2. Place the mounting attachments on the support points.
3. Tighten retaining screws.
Observe max. tightening torque and max. screwin depth.

7.5 Mounting the Attachment Component
Torque on the Piston Rod
During commissioning and operation, the piston rod may only be operated
without torque.
If external torques occur, an external guide must be used.
Mounting the Attachment Component on the Piston Rod
When attaching the attachment component, do not exceed the max. torque of the
piston rod. The max. torque of the piston rod may only be used for a short time
during mounting è Tab. 7 Information on Attachment Components.

Tab. 5 Requirement for Attachment Component
Requirement
– No collision in the movement space of the attachment component with
mounting and sensor components.
– No lateral force or torque on the piston rod.
Absorb external forces and torques via an external guide.
– Position of the centre of gravity and tilting moment (forceF parallel to the
axis of movement) of the attachment component centrally and close to the
piston rod (short lever arma).
– The maximum screwin depth of the retaining screws is not exceeded.
1. Select accessories èwww.festo.com/catalogue.
2. Screw the lock nut onto the male thread of the piston rod or attachment com
ponent.
3. Rotate or place the attachment component on the piston rod.
4. Tighten retaining screws or lock nut.
The tightening torque must not act on the piston rod. Counterhold with a suit
able tool on the spanner flat of the piston rod.
Observe max. tightening torque and max. screwin depth.

When using an additional external guide, ensure that the electric cylinder and pis
ton rod are parallel and aligned exactly.
