Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-10S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-10S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 450mm 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 SGCJ250X450-10S
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles heavy industrial tasks with ease. The four steel tie rods clamp the aluminum barrel securely, while the G1 air port supplies the massive volume needed for the 250 mm bore. A built-in piston magnet comes standard, ready for CMSG, DMSG or EMSG position switches.
The external adjuster lets you shorten the extend stroke on-site by up to 10 mm, giving a usable range of 440 to 450 mm without changing the cylinder itself. This on-site fine-tuning is perfect for dialing in exact end positions. It yields a safe working load of about 14726 N, roughly 1251 kg lifted vertically with a 2:1 margin. Note that TPU seals are not offered on this 250 mm bore; it uses NBR packings, with a Viton H option for 0 to 150 C environments.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-10S Is Used
Heavy Pallet Forming
Drives large platens to compress pallets, using the 10 mm extend adjuster to perfectly tune the final pressing height on-site without swapping cylinders.
Stamping Press Feed
Pushes heavy billets into a forming press, relying on 24543 N of thrust at 0.5 MPa and the G1 port to maintain steady high-force movement.
Automated Door Actuation
Opens massive industrial warehouse doors, utilizing the 60 mm adjustable air cushions to decelerate the heavy load smoothly at the end of travel.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-10S the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range, providing 24543 N push and 23562 N pull at 0.5 MPa. If your application only needs 15708 N of push force, stepping down to the 200 mm bore saves air volume and cost. The adjustable stroke feature is highly valuable here, allowing you to stock one 450 mm cylinder and fine-tune the end position across 10 mm to cover slight variations across multiple machines. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. Because the -S magnet is present, you can directly mount CMSG, DMSG or EMSG sensors. For a 450 mm stroke, ensure you use a guide rail to absorb side loads and prevent rod bending.
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 SGCJ250X450-10S FAQ
This 250 mm bore cylinder features a G1 air port and a 50 mm rod. It generates 24543 N push and 23562 N pull at 0.5 MPa, 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical maximum of 5006 kgf at 1.0 MPa.
An external stop screw lets you shorten the extend stroke on-site by up to 10 mm, providing a usable extend range of 440 to 450 mm. The nominal 450 mm stroke is the maximum, and the retract end remains fixed. This mechanism only sets the end position and does not lock the load.
