Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-20
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-20 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 80mm 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 SGCJ250X80-20
Delivering massive thrust, this 250 mm bore tie-rod actuator pushes 24543 N and pulls 23562 N at 0.5 MPa. Built to genuine ISO 15552 dimensions, it drops directly into existing large-bore mounting interfaces. The four steel tie rods clamp the aluminum barrel securely to the covers. A G1 air port feeds the chamber, while 60 mm adjustable air cushions absorb end-of-stroke impacts.
The -20 code defines a 20 mm external adjuster window, letting you shorten the extend stroke on-site from the 80 mm maximum down to 60 mm without changing the cylinder. This yields a safe working load around 14726 N, or roughly 1251 kg lifted vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors. Also, TPU seals are unavailable for this bore; it uses NBR packing, with a Viton H option for 0-150 C environments.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-20 Is Used
Press Tonnage Trimming
Apply 34360 N of extend force at 0.7 MPa to seat heavy components, using the 20 mm adjuster to dial in the exact 60-80 mm contact position.
Heavy Pallet Lifting
Lift roughly 1251 kg vertically with a 2:1 safety margin, relying on the rigid tie-rod frame to stabilize massive loads during elevation.
Large Gate Actuation
Drive heavy industrial gates using the G1 port for high airflow, tweaking the extend end-point on-site to match the valve seat perfectly.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-20 the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range; step down to a 200 mm bore (15708 N push at 0.5 MPa) if your force needs are lower. The 20 mm adjustable window is ideal for fine-tuning the extend end position on-site, allowing one shared spare across slightly different stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a non-magnet SKU, position sensing is impossible. For any application, remember a plain cylinder drifts on air loss—the cushion only decelerates, so fit an external rod lock or pilot-operated check valve to hold loads securely.
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 SGCJ250X80-20 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 is 5006 kgf at 1.0 MPa.
The nominal 80 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 20 mm on-site, giving a usable range of 60-80 mm. The retract end remains fixed.
