Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X400-10S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X400-10S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 400mm 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 SGCJ250X400-10S
Delivering massive thrust for heavy industry, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. The four steel rods clamp the aluminum barrel securely, while the built-in piston magnet supports CMSG, DMSG, and EMSG sensors for precise position detection.
A 10 mm external adjuster lets you fine-tune the extend end position on-site, meaning you can shorten the usable extend stroke from 400 mm down to 390 mm without changing the cylinder itself. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin. This 250 mm bore uses a G1 port, a 50 mm rod, and Viton H high-temperature seals up to 150 C because TPU is unavailable here.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X400-10S Is Used
Heavy Pallet Lifts
Raises loaded pallets in automated warehouses, using the 10 mm stroke adjuster to dial in the exact transfer height.
Press Ejection
Pushes finished parts out of large stamping presses, relying on the 60 mm adjustable air cushions to halt the 50 mm rod smoothly.
Bulk Gate Actuation
Opens heavy hopper gates in cement plants, benefiting from the 24543 N thrust and Viton H seals for high process heat.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X400-10S the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range, pushing 24543 N at 0.5 MPa; step down to a 200 mm bore for 15708 N if your load permits. The 10 mm adjustable window is ideal for sharing one spare cylinder across multiple stroke variants or fine-tuning machine stops. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix provides the magnet needed for switches. For any stroke over 500 mm, always use external guide rails to prevent rod side-loading damage.
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 SGCJ250X400-10S 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 force is 5006 kgf at 1.0 MPa.
The nominal 400 mm extend stroke is the maximum. The external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable range of 390 to 400 mm. The retract end remains fixed, and this mechanism sets the end position rather than locking the load.
