Frequently Asked Questions - DFM-16-100-B-PPV-A-GF Festo

What is the operating pressure range for the DFM-16-100-B-PPV-A-GF?

The operating pressure range is 1 to 10 bar. For optimal performance, use filtered compressed air.

Can I use this cylinder without additional lubrication?

Yes, the cylinder is designed for maintenance-free operation with filtered compressed air. No additional lubrication is required for the entire service life.

How do I mount the DFM-16-100-B-PPV-A-GF?

The cylinder can be mounted using threaded holes on the body and/or mounting accessories like foot mounts or flange plates. Ensure the mounting surface is flat and rigid.

What is the theoretical force output at 6 bar?

At 6 bar, the advance force is approximately 120 N and the return force is approximately 104 N due to the piston rod area difference.

Can I use proximity switches for position sensing?

Yes, the cylinder has a slot for proximity switches (e.g., Festo SME/SMT series). They can be mounted along the stroke for end-position or intermediate sensing.

What is the maximum allowed side load?

The guided design allows for moderate side loads, but for maximum life, minimize side forces. Refer to the manual for exact permissible moments.

How do I adjust the cushioning?

Cushioning screws are located at both ends of the cylinder. Turn the screw clockwise to reduce cushioning (harder stop) or counterclockwise to increase cushioning (softer stop). Adjust in small increments.

What spare parts are recommended?

Common spare parts include seal kits (rod seal, wiper, piston seal) and cushioning screw sets. For the guide, linear bearings and guide rods are available separately.

Is the cylinder suitable for outdoor use?

The standard version is designed for indoor use with ambient temperatures from -10 to 60 °C. For outdoor or corrosive environments, use stainless steel or coated variants.

How do I replace the seals?

Disassemble the cylinder by removing the end caps. Replace the old seals with new ones from the seal kit. Apply a thin film of grease on the seals before reassembly. Torque the end caps to specified values.

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 (II) and (I) 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 dt:

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 8 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.
Tighten the lock nut (D). Observe the tightening torque M_tot (→ Table).	Tighten 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 test 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).
