Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-30
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-30 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 300mm 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 SGCJ250X300-30
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, and the G1 air port feeds the 50 mm piston rod. It handles a safe working load of roughly 14726 N, which means you can vertically lift about 1251 kg with a 2:1 safety margin.
The -30 code defines an external adjuster that lets you shorten the extend stroke on site by up to 30 mm, giving a usable range of 270 to 300 mm without changing the cylinder itself. Because it is dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. Note this SKU lacks a magnet and cannot take a sensor, and since TPU is unavailable on a 250 bore, the seals are NBR with a Viton H option for 0 to 150 C environments.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-30 Is Used
Heavy Press Tuning
Use the 30 mm extend adjuster to precisely set the bottom dead center on a 1251 kg vertical press operation without machining new spacers.
Pallet Stop Calibration
Fine-tune the stopping distance of heavy 250 mm bore actuators on a conveyor line by dialing the extend stroke back from 300 mm to 270 mm.
Mold Alignment
Adjust the extend end position on-site to perfectly seat heavy molds, compensating for mechanical wear over time using the external stop screw.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-30 the Right Cylinder?
Size this 250 mm bore against the neighbouring 200 mm class, which provides 15708 N of push at 0.5 MPa, to ensure you are not over-specifying. If you need more than 24543 N at 0.5 MPa, this is your high edge. The 30 mm adjustable extend window is perfect for sharing one spare across multiple stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because the standard stroke is 300 mm, guide any side loads to prevent rod bending. Remember that a plain cylinder drifts without live air, so fit an external rod lock or pilot-operated check valve if you need to hold a load.
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 SGCJ250X300-30 FAQ
At 0.5 MPa it pushes with 24543 N and pulls with 23562 N. At 0.7 MPa the push is 34360 N and the pull is 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa. It uses a G1 port and a 60 mm adjustable air cushion at each end.
The nominal 300 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable extend range of 270 to 300 mm. The retract end remains fixed. This mechanism sets the end position and is not a load lock.
