Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-100
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-100 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 900mm 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 SGCJ250X900-100
Delivering massive thrust for heavy industry, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity for high-force cycles. It feeds air through a G1 port and decelerates smoothly via 60 mm adjustable air cushions at both ends.
The -100 code means an external adjuster can shorten the extend stroke on-site by up to 100 mm, letting you fine-tune the end position from 800 to 900 mm without changing the cylinder itself. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops into existing large-bore fixtures. This non-magnet SKU cannot take a sensor, but the -S variant supports CMSG/DMSG/EMSG switches. It handles a safe working load of about 14726 N, which means you can vertically lift roughly 1251 kg with a 2:1 margin. Note that TPU seals are unavailable here; NBR is standard, with a Viton H option for 0-150 C heat.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-100 Is Used
Heavy Press Ejection
Ejects large formed parts from hydraulic presses, using the 100 mm extend adjuster to dial in the exact ejection point without repositioning the heavy cylinder.
Stamping Clamp Stop
Acts as a heavy-duty clamping stop in stamping lines, fine-tuning the 800-900 mm stroke window on-site to accommodate different die heights.
Large Mold Handling
Moves heavy injection molds along the production line, relying on the 60 mm cushions to decelerate the massive payload safely at the end of travel.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-100 the Right Cylinder?
Size this 250 mm bore against the 200 mm option, which provides 15708 N push at 0.5 MPa, or step up if you need the absolute maximum 5006 kgf at 1.0 MPa. The adjustable stroke is ideal when you need on-site end-position tuning across shared spare parts, letting one cylinder cover a 800-900 mm window. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a non-magnet model, it cannot accept position sensors; specify the -S variant if you require CMSG/DMSG/EMSG switches. For a 900 mm stroke, always use external guides to prevent rod bending and manage side loads.
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 SGCJ250X900-100 FAQ
At 0.5 MPa it pushes with 24543 N and pulls with 23562 N. At 0.7 MPa it pushes with 34360 N and pulls with 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa. This 250 mm bore cylinder uses a G1 air port.
The -100 code means an external stop screw shortens the extend stroke by up to 100 mm on-site. The usable extend range is 800-900 mm, with 900 mm being the maximum nominal stroke. The retract end is fixed. This mechanism sets the end position but does not lock the load; use an external rod lock or pilot-operated check valve to hold a load on air loss.
