Pneumatic Cylinder XCPC DNC-32×160-S (ISO 15552)

1. Purpose and operating principle

When compressed air is supplied to one chamber, the piston moves, generating force on the rod. The return stroke is performed by supplying air to the opposite chamber. The magnetic piston (code S) allows non-contact position sensors (SME/SMT-8 type or equivalents) to be mounted in the profile grooves of the barrel.

The cylinder fully complies with ISO 15552 mounting and connection dimensions, ensuring interchangeability with Festo DNC, SMC C96, Camozzi 60, Airtac SC and other cylinders.

2. Technical specifications

⚠️ Unconfirmed data (not stated in the public XCPC datasheet): exact cylinder weight, tightening torques, corrosion resistance class CRC, ATEX/RoHS certificates. Please confirm with an Acvatron SRL manager or request the datasheet for the specific batch.

3. Design features

Part number breakdown DNC-32×160-S

Design solutions

• Aluminium profile barrel with sensor grooves on four sides.

• Adjustable needle valves for cushioning on both end covers.

• Wear-resistant piston guide ring and rod seals.

• Compatible with standard ISO 15552 mountings (LB, FA, FB, CA, CB, SDB, etc.).

• Compact design — saves installation space compared with older-standard cylinders.

4. Installation recommendations

• Port threads are G1/8″ (BSPP, parallel). Seal with a flat gasket or O-ring. Do not use PTFE tape (FUM) — fragments can enter the pneumatic system.

• Piston rod thread M10×1.25 is metric cylindrical. Connection is made with a nut and lock-nut or a clevis/rod-end. No sealing is required.

• Mounting position — any. For vertical installation with rod down, protect against moisture and dirt.

• For tools that require lubrication, install a separate lubricator in the line (DNC series has no built-in greaser).

• Position sensors are mounted in the profile grooves and secured with a screw. Recommended types: SME-8, SMT-8 or compatible.

• Before first start-up, purge the lines of chips and contamination. Working air must meet cleanliness class 7:4:4 or better according to ISO 8573-1.

5. Cross-references and comparison

Cross-references (verify parameters before replacement)

⚠️ Before replacement always check: presence of magnet, cushioning type, rod thread and overall dimensions from the drawing.

6. Common mistakes

1. Using PTFE tape on G1/8″ ports — tape fragments enter the pneumatic system and damage valves/sensors.

2. Installation without adjusting the cushioning — hard impact at end of stroke, premature wear of seals and guides.

3. Operating above 10 bar — exceeding the allowable pressure destroys the seals.

4. Lack of air filtration — abrasive particles and moisture rapidly reduce cylinder service life.

5. Incorrect mounting selection — side loads on the rod cause premature wear of the guide bushing.

7. Application areas

• Assembly and packaging machines

• Conveyor systems and manipulators

• Clamping and holding devices

• Light pressing and ejecting mechanisms

• Food, woodworking and light-industry equipment (provided air cleanliness requirements are met)

8. Expert opinion

“The XCPC DNC series is one of the most popular replacements for European ISO 15552 cylinders on the Moldovan market. With proper air preparation and cushioning adjustment, service life is comparable to original Festo/SMC units at a significantly lower cost. The key is not to economise on air preparation and to set the cushions correctly.”

9. FAQ

1. Can Festo DNC-32-160-PPV-A be replaced by XCPC DNC-32×160-S without modifying the mountings?
Yes. Both cylinders comply with ISO 15552 — mounting holes, centre distances and connection dimensions are identical.

2. What does the “S” code in the part number mean?
Magnetic piston. Allows non-contact position sensors to be mounted in the barrel profile grooves.

3. What is the maximum allowable pressure?
1.0 MPa (10 bar). Test pressure is 1.5 MPa.

4. Is a lubricator required?
For standard operation — no. If the cylinder works with tools that require lubrication, install a separate lubricator in the line.

5. What thread is on the rod and how is it sealed?
M10×1.25 (male metric). No sealing is required — the connection is mechanical.
