Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-100
The AirTAC SGCJ200-250 Adjustable Cylinder SGCJ250X700-100 is a genuine double acting, double rod, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 700mm stroke, G1 air ports and adjustable end cushioning. Its large-bore tie-rod build delivers high thrust and drops into standardized ISO 15552 mounting on heavy automation.

About the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-100
Four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity for heavy-duty cycles.
The nominal 700 mm stroke serves as the maximum travel, allowing you to shorten the extend distance by up to 100 mm without changing the cylinder mounting. Because this is a 250 mm bore, the standard TPU seal is unavailable; instead, NBR packings handle the -20 to +70 C range, with a Viton H option for 0-150 C environments. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors without upgrading to the -S variant.

Theoretical Output Force (Ø250mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |
| 0.7 MPa | 32987 N | 32987 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 SGCJ250X700-100 Is Used
Heavy Pallet Lifting
Raises loaded pallets in automated distribution hubs, using the 100 mm adjuster to dial in exact upper conveyor transfer heights without remounting the hardware.
Stamping Clamp Descent
Lowers heavy clamping platens in fabrication cells, shortening the extend stroke on-site to accommodate different material thicknesses while utilizing the 60 mm cushions for soft stops.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-100 the Right Cylinder?
The adjustable stroke is particularly useful when you need to share a single spare cylinder across multiple stroke variants or dial in a precise end position on the machinery. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the 700 mm stroke is substantial, always use external guides and rod-end support to prevent side-load bending on the 50 mm rod.
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 SGCJ250X700-100 FAQ
The theoretical maximum force is 5006 kgf at 1.0 MPa. It features a 250 mm bore, a 50 mm rod with an M42x2.0 thread, a G1 air port, and 60 mm adjustable air cushions at both ends.
The 700 mm nominal stroke is the maximum travel. The external adjuster lets you shorten the extend stroke by up to 100 mm on site, giving a usable extend range of 600 to 700 mm. The retract end remains fixed. This mechanism only sets the end position; a plain cylinder does not hold load on air loss, so use an external rod lock or pilot-operated check valve for load holding.
