Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-30
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-30 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 SGCJ250X900-30
Generating up to 5006 kgf of theoretical maximum force at 1.0 MPa, this large-bore ISO 15552 tie-rod cylinder handles heavy industrial tasks. The four steel tie rods clamp the aluminum barrel securely to the covers, while the G1 air port feeds the 50 mm piston rod. It delivers 24543 N of push force at 0.5 MPa, translating to a safe working load of about 14726 N or a 1251 kg vertical lift with a 2:1 margin.
The external adjuster shortens the extend stroke on-site by up to 30 mm, letting you fine-tune the end position without changing the cylinder. The nominal 900 mm stroke remains the maximum, yielding a usable extend range of 870-900 mm. Because this is a 250 mm bore, TPU seals are unavailable; NBR packing is standard, with a Viton H option for 0-150 C heat. This non-magnet SKU cannot take a sensor.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-30 Is Used
Heavy Press Ejection
Delivers 34360 N push at 0.7 MPa to eject large formed parts, with the 30 mm adjuster tuning the ejection reach to clear the press bed.
Stamping Clamp Stop
Provides massive clamping force, using the external stop screw to dial in the exact 880 mm clamp position without reworking fixtures.
Large Mold Handling
Shifts heavy injection molds along the 900 mm stroke, relying on the rigid tie-rod frame to maintain alignment under high inertial loads.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-30 the Right Cylinder?
When sizing, the 200 mm bore neighbor offers 15708 N push at 0.5 MPa, while this 250 mm bore hits 24543 N, marking the top standard range. The 30 mm adjuster is ideal for sharing a spare across stroke variants or finalizing end positions on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. For the 900 mm stroke, external guides are critical to prevent rod bending and manage side loads. Note that a plain cylinder drifts on air loss; use an external rod lock for held 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 SGCJ250X900-30 FAQ
It features a G1 air port and a 50 mm rod. 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.
The external stop screw shortens the extend stroke by up to 30 mm on-site, giving a usable extend range of 870-900 mm. The nominal 900 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position and does not lock the load.
