Pneumatic Cylinder XCPC DNG-160×200-S

1. Purpose and Operating Principle

Standard double-acting pneumatic cylinder of the DNG series (ISO 15552) with magnetic piston. Designed for powerful linear motion in industrial automation: pressing operations, clamping devices, lifting and pushing mechanisms, assembly lines with high loads.

The Ø160 mm piston and 200 mm stroke provide a theoretical forward force of more than 12 000 N at 6 bar working pressure. It operates on the double-acting principle: compressed air supplied to the corresponding chamber moves the piston; return is provided by pressure from the opposite side.

The piston is fitted with a permanent magnet (code S) for use with inductive and reed position sensors — the cylinder integrates easily into instrumentation and PLC control systems without additional accessories.

3. Design Features

Part number breakdown

Design solutions

• Body: aluminium profile to ISO 15552 with longitudinal slots for position sensor mounting.

• Rod: alloy steel, rod end with male thread M36×2.

• Port: G 3/4″ female thread (BSPP).

• Cushioning: adjustable pneumatic cushioning at both ends — smooth stopping under heavy loads and high speeds.

• Mounting: normal (standard) version, plus FA, FB, CA, CB, LB, TC — wide choice for any machine frame layout.

• Lubrication: not required when clean filtered air is used. If oil is introduced via a lubricator, subsequent oil supply must be continuous.

4. Installation Recommendations

1. Port thread G 3/4″ — parallel (BSPP): seal with a flat gasket, no PTFE tape.

2. Rod thread M36×2 — metric; select the rod end and mating thread strictly to this pitch.

3. Adjustable cushioning must be set to the actual load mass and cycle speed after installation.

4. Under side loads on the rod fit an external linear guide — service life of the rod bushes and seals increases significantly.

5. For the 160 mm bore it is recommended to fit flow-control valves with check function on each line — simplifies speed control and prevents rod surges.

6. Ensure air filtration: with the large piston area contaminants wear seals out faster.

7. Minimum working pressure is 1 bar — higher than compact series; allow for this when designing low-pressure systems.

5. Equivalents and Comparison

All models below comply with ISO 15552, 160 mm bore, 200 mm stroke, double-acting, with magnetic piston.

Important: when replacing, check the mounting style — each manufacturer codes it differently, but overall and connection dimensions to ISO 15552 are identical for the same bore.

Comparison with neighbouring XCPC series:

• DNC — bores 32–125 mm, more modern.

• SI — ISO 6431 standard (up to 200 mm).

• DNG — heavy-duty series specifically for bores 160–320 mm where high force is required.

6. Common Mistakes

• Exceeding working pressure above 10 bar (proof pressure of 15 bar is not intended for continuous duty).

• Running with factory (unadjusted) cushioning under heavy load — impact loads and accelerated wear.

• Intermittent rather than continuous use of lubrication after it has been introduced once — washing out of the factory grease.

• Using non-standard (non-ISO 15552) mounting elements — loss of interchangeability and risk of misalignment.

• Underestimating the load on the machine support structure at full force (~1 230 kg at 6 bar).

• Selecting the cylinder by bore only without allowing for the 1 bar minimum pressure.

7. Applications

• Industrial automation and robotics

• Pressing and stamping operations

• Clamping and holding devices

• Lifting and pushing mechanisms

• Packaging equipment

• Woodworking and metalworking

• Assembly lines with high cyclic loads

8. Expert Opinion

Vitali Boluchevski, Lead Engineer, Acvatron SRL, 18 years of experience:

“In the large-bore segment the quality of the tube bore finish and the cushioning adjustment are decisive. With proper air preparation and buffer setting the DNG-160×200-S really lasts for years. The key points are not to skimp on filtration and not to leave the cushion ‘as shipped’ under real load. Replacing a Festo/SMC of the same bore and stroke needs no frame modification thanks to ISO 15552.”

9. FAQ

1. Can a Festo DNC-160-200 be replaced by an XCPC DNG-160×200-S without modification?
Yes. Both cylinders comply with ISO 15552 — mounting and connection dimensions are identical. Replacement takes 20–30 minutes with no changes to the machine frame.

2. Is lubrication required?
No. With clean filtered air the cylinder runs without external lubrication. If a lubricator is already installed, oil supply must be continuous.

3. Which sensors are compatible?
Any reed and inductive sensors for ISO 15552 slots. Suitable series include XCPC XC-31R, XC-21R, Festo SME/SMT equivalents, SMC D-A93 — they fit in the longitudinal body slots without extra brackets.

4. What is the working pressure range?
From 1 to 10 bar. The 1 bar minimum is higher than that of compact series.

5. What force does the cylinder develop at 6 bar?
Theoretical forward force ≈ 12 063 N (~1 230 kg), return force ≈ 10 700 N (~1 090 kg).
