onment. Ensure that storage times are kept to a minimum.
– Prior to mounting, installation and maintenance work: Switch off compressed
air supply and secure it from being switched back on.
– Observe tightening torques. Unless otherwise specified, the tolerance is
±20%.

5 Product overview
5.1 Function
The piston rod moves outwards when the cylinder chamber is pressurised. The
advanced piston rod is retracted as follows:
– For double-acting cylinders, by pressurising the other cylinder chamber.
The cylinder force during advance and return is:
– different with piston rod at one end.
– identical with through piston rod.
The position of the piston can be detected by proximity switches.

5.3 Mounting
• Handle the cylinder so as to avoid any damage to the cylinder barrel and pis-
ton rod.
• Observe the following points:
– parallel mounting when using external guides
– installation without distortion
– Compliance with the permissible loads www.festo.com/catalogueè
• Observe tightening torque of lock nuts on the male thread .2

Tab. 1 Tightening torques on the bearing cap
• Avoid mechanical alignment inaccuracies between the piston rod and an
external guide using one of the following measures:
– absolutely precise alignment (general)
– use of a self-aligning rod coupler FK
– use of a guide unit FEN with compensating coupling
A rigid coupling impairs the service life and function of the cylinder.
5.4 Mounting Accessories
In the case of a large payload, high piston speed or when using quick exhaust
valves:
• Use suitable shock absorbers or external stops.
To prevent the payload from sliding down suddenly in the event of an air supply
failure in a horizontal or sloping mounting position:
• Use piloted check valves.
To set the speed:
• Use one-way flow control valves in the following supply ports:
– For single-acting cylinders: GRLZ (supply air)
– For double-acting cylinders: GRLA (exhaust air)
The one-way flow control valves are screwed directly into the supply ports. Use of
other accessories with a screw-in depth that is too long will damage the cushion-
ing piston.
For position sensing with proximity sensors:
• Use proximity sensors with mounting kit.
Avoid external influence caused by magnetic or ferritic parts in the vicinity of
the proximity sensors (spacing 10mm).³
6 Installation
6.1 Pneumatic Installation
• Connect tubing to supply ports.
7 Commissioning
7.1 Preparation
• Pressurise the system slowly. A soft start valve is used for gradual start-up
pressurisation www.festo.com/catalogue. è
With medium or large payloads or at high speeds:
• Use sufficiently large arrester fixtures. The product will tolerate the maximum
velocities and payloads without external arrester fixtures
