1. Purpose and operating principle
The XCPC DNC-63×100-S is a double-acting pneumatic cylinder. Compressed air is alternately supplied to the two cylinder chambers.
Operating sequence:
- Compressed air enters the piston-side chamber.
- Pressure acts on the Ø63 mm piston.
- The piston extends the rod.
- When the directional valve switches, air enters the rod-side chamber.
- The piston returns to its initial position.
- Pneumatic cushioning reduces piston speed at the end of the stroke.
- If the magnetic version is specified, a sensor installed in the cylinder groove can detect piston position.

Theoretical force
The piston area for Ø63 mm is approximately 3117 mm².
At 6 bar, the theoretical extension force is approximately 1870 N. Actual useful force will be lower because of seal friction, back pressure and other losses.
⚠️ The specifications above are based on XCPC DNC series manufacturer data. For a specific order, the exact configuration should be confirmed, especially the presence of the piston magnet and installation dimensions.
3. Design features
| Code element | Meaning |
|---|---|
| DNC | Standard profile pneumatic-cylinder series |
| 63 | 63 mm piston diameter |
| X | Separator used in XCPC coding |
| 100 | 100 mm stroke |
| S | XCPC configuration/variant identifier; the exact meaning should be checked against the manufacturer’s ordering code |
Key design features:
- DNC-type profile construction;
- double-acting operation;
- Ø63 mm bore;
- 100 mm stroke;
- adjustable pneumatic cushioning;
- optional magnetic piston for position sensors;
- G3/8 pneumatic ports;
- Ø20 mm rod with M16×1.5 thread.
4. Installation recommendations
- Verify the Ø63 mm bore and 100 mm stroke.
- Check all mounting dimensions before replacing an existing cylinder.
- Verify the M16×1.5 rod thread.
- The cylinder port is G3/8.
- Use properly filtered and prepared compressed air.
- Use flow-control valves with check valves when controlled speed is required.
- Adjust end-of-stroke cushioning gradually; excessive restriction can slow the cylinder unnecessarily.
- Avoid lateral loads on the rod. Use external guides where transverse forces occur.
- If position sensors are required, confirm the magnetic version.
- Do not confuse cylindrical G/BSPP threads with BSPT. Sealing must be selected according to the actual thread type and fitting design.
5. Equivalents and comparison
Same-size alternatives

|---|---|---|---|---|
| XCPC | DNC-63X100-S | 63 mm | 100 mm | DNC series |
| Festo | DNC-63-100-PPV-A, 163405 | 63 mm | 100 mm | Comparable ISO 15552 version |
| SMC | C95, corresponding configuration | 63 mm | 100 mm | Verify exact configuration |
| Parker | P1D, corresponding configuration | 63 mm | 100 mm | Verify exact configuration |
These are reference points for selecting an alternative, not a declaration of direct interchangeability. Before replacement, compare mounting dimensions, rod thread, ports, cushioning and sensor arrangement.

6. Common mistakes
- Selecting the cylinder only by piston diameter.
- Confusing XCPC DNC-63X100-S with Festo DNC-63-100-PPV-A.
- Assuming that every version includes a magnet.
- Ignoring the rod thread and mounting dimensions.
- Applying lateral loads directly to the rod.
- Incorrectly adjusting the end-of-stroke cushioning.
- Choosing the wrong thread type or sealing method.
7. Applications
XCPC DNC-63×100-S can be used in:
- industrial automation;
- packaging machines;
- machine tools;
- conveyor systems;
- feeding mechanisms;
- clamping devices;
- positioning systems;
- automatic assembly lines;
- sorting mechanisms;
- special pneumatic actuators.
Compatibility with a particular machine should be determined from the actual mechanical dimensions and system requirements.
8. Expert opinion
“Vitali Boluchevski, Lead Engineer, Acvatron SRL, 18 years of experience”:
When replacing a pneumatic cylinder, I recommend checking more than bore and stroke. For DNC cylinders, mounting dimensions, rod thread, port position and the version with or without a magnet are also important. In practice, these details are often what determines whether a cylinder that looks identical can actually be installed as a direct replacement. For equipment operating intensively in Moldova, compressed-air quality should also be checked because contamination and condensate directly affect seal life.
9. FAQ
Can XCPC DNC-63X100-S replace a Festo DNC-63-100-PPV-A?
It can be considered an alternative of the same general DNC/ISO 15552 size, but direct replacement must be confirmed by comparing mounting dimensions, rod thread, ports and cushioning configuration.
What force does a Ø63 mm cylinder produce?
At 6 bar, the theoretical extension force is approximately 1870 N. Actual force will be lower due to mechanical and pneumatic losses.
Does the cylinder have a magnet?
The magnet is optional for the XCPC DNC series. If a position sensor is required, the corresponding magnetic configuration must be specified and confirmed.
What fittings are required?
For the Ø63 mm version, XCPC specifies a G3/8 pneumatic port.
What is the rod thread?
For Ø63 mm, XCPC specifies an M16×1.5 rod thread.
