7. Mounting, general

→ Note

In order to avoid operative malfunctions and increased wear

• Observe the characteristic curves and permissible limits
- Handle the guide units [1] through [5] in such a way that the guide rods and piston rod are not damaged.
- Ensure that the mounting surfaces 0f and 0i are flat.
• Install guide units 1 through 5 without distortion

Mounting variants:

a) Flat from on top

c) Lateral from underneath

b) Flat from underneath

d) On front end ^2051

• Use the following screws 7 and centring sleeves 6 , depending on the mounting variant:

i Information

To mount guide units [1 through 5]

- If possible, use screws [7] with a screw-in length of 1.5 x d ^20 .

- Fasten the guide unit according to load, size and stroke length, but with at least 2 screws [7].

X=1.5

→ Note

To mount the variant d):

With protruding guide rods in the retracted state:

- Ensure there is clear passage of the guide and stop rods, e.g. through grooves in the mounting surface (H).

8. Mounting the proximity sensors

When intermediate strokes are being sensed, the proximity sensor can be at the level of a fastening hole (K) and not fastened.

• Take the following assembly alternatives e) through g) into consideration:

c) Offset the proximity

sensor's within its

operating path (b) by 6 mm.

f) Rotate the proximity

sensor 8 by 180°.

g) Select another permissible proximity sensor

(→ www.festo.com/catalogue)

- As required, cover the sensor slots with a slot cover AB ^2 [9] and use them to fix the cables into place (→ More detailed information).

9. Stroke adjustment

9a. For guide units 2 through 4 (no metallic stop)

- Vent the guide units 2 through 4.

→ Note

To avoid the unintentional loosening of the piston rod:

- When loosening and tightening the lock nut (F), counterhold the stop nut (G).

Retracted end position (EJ)
Extended end position (AI)

Loosen the lock nut (D).	Loosen the lock nut (F).
Adjust the stop rod (Y) with the internal hexagon socket (E).	Adjust the stop rod (G).
Shorten the stroke by a maximum of 10 mm.	Shorten the stroke by a maximum of 10 mm.
Tighter the lock nut (D). Observe the tightening torque M_tot (→ Table).	Tighter the lock nut (F). Observe the tightening torque M_tot2 (→ Table).

- Vent the guide units 2 through 4.

- Start the test run. Check the set stroke.

5) Tolerance for tightening torques K_u with no indication of tolerance: ± 20%

9b. For guide unit 5 (metallic stop)

DEM-...B-YSRW

- Vent the guide unit [5].

→ Note

- To reduce the shortening of the stroke dimension a by a maximum of 10 mm and enlarge it by dimension l by a maximum of 10 mm (→ Section 1.1). - Do not exceed fall short of dimension all since the shock absorber performance is otherwise strongly reduced.

- Adjust the shock absorber (B) to dimension a/l as follows:

Retracted end position

Extended end position

Loosen the lock nut (A)

Adjust the shock absorber (B).

Observe dimension L increase the factory-set stroke by a maximum of 10 mm (→ Table).

Tighten the lock nut (A). Observe the tightening torque M_a (→ Table).

- Vent the guide unit [5].

- Start the best run. Check the set stroke.

10. Maintenance and care

10a. In case of guide unit 5

During operation, the viscosity of the hydraulic oil reduces due to friction heat.

→ Shock absorber reset times become shorter (hard knocking).

At low temperatures around 0°C, the viscosity of the hydraulic oil rises.

→Shock absurber reset times become longer.

The moving mass should always reach the end position safely, but not knock hard against it.

- The shock absorbers should be replaced when their functioning / shock

absorbing performance is no longer ensured due to excessive wear.

- Check the cushioning regularly for the following signs of wear:

Oil leakage

- Hard knocking

- Stop rod remains in retracted end position / moves slowly from end position

• The following environmental conditions shorten the test intervals:

High thermal stress

- Severe accumulation of dirt

– Proximity of grease-dissolving liquids or vapours.

• Exchange the shock absorber (B) after 10 million strokes (→ Section 9b).
