About the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X200-75
Delivering massive thrust with on-site flexibility, this large-bore ISO 15552 tie-rod cylinder pushes 24543 N and pulls 23562 N at 0.5 MPa. The four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity. It features a G1 air port, an M42x2.0 rod thread, and 60 mm adjustable air cushions at both ends. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures.
The -75 code denotes an external adjuster that shortens the extend stroke on-site by up to 75 mm, yielding a usable extend range of 125 to 200 mm without changing the cylinder itself. This lets you fine-tune the end position perfectly, while the retract end remains fixed. Note that TPU seals are unavailable for this 250 mm bore; it uses NBR seals, with a Viton H option for 0 to 150 C environments. Since this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors.

Theoretical Output Force (Ø250mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |

SGCJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X200-75 Is Used
Press Tonnage Tuning
Dial in the exact bottom dead center of a 1251 kg forming press by adjusting the extend stroke on-site by up to 75 mm.
Heavy Pallet Stops
Act as a rugged 24543 N shock stop for automated guided vehicles, using the 60 mm cushions to absorb heavy impacts.
Fixture Positioning
Securely clamp oversized fabricated steel components in welding cells with fine-tuned extend end positions.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X200-75 the Right Cylinder?
The adjustable stroke is ideal for sharing a spare cylinder across multiple stroke variants or dialing in end positions on-site. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because this is a non-magnetized SKU, you cannot mount position sensors; choose an -S variant if you require CMSG, DMSG, or EMSG switches. For any stroke over 500 mm, always use external guide rails to prevent side-load damage. A plain cylinder drifts on air loss, so add an external rod lock or pilot-operated check valve for load holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Long-stroke side load — support the rod end
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load; support long strokes at the rod end.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X200-75 FAQ
At 0.5 MPa it pushes 24543 N and pulls 23562 N. At 0.7 MPa it pushes 34360 N and pulls 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa. It uses a G1 air port, a 50 mm rod, an M42x2.0 rod thread, and 60 mm adjustable air cushions.
The -75 code means an external stop screw shortens the extend stroke by up to 75 mm on-site. With a 200 mm nominal stroke, the usable extend range is 125 to 200 mm. The retract end is fixed. This mechanism sets the end position but is not a load lock.
