Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-30S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-30S 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 SGCJ250X450-30S
Delivering massive thrust in a large-bore format, this ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. The four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity for heavy-duty cycles. A built-in piston magnet supports CMSG, DMSG and EMSG switches for position sensing.
The external adjuster allows you to shorten the extend stroke on-site by up to 30 mm, giving a usable range of 420 to 450 mm without changing the cylinder. This on-site fine-tuning is ideal for shared spares across stroke variants. It handles a safe working load of about 14726 N, roughly 1251 kg lifted vertically with a 2:1 margin. The G1 port feeds the 50 mm rod, and Viton H seals can raise the temperature limit to 150 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-30S Is Used
Heavy Pallet Forming
Apply 24543 N of push force at 0.5 MPa to compact large pallet loads, using the 30 mm adjuster to fine-tune the final press height on-site.
Large Gate Actuation
Drive heavy industrial gates with a 50 mm rod and G1 port, shortening the extend stroke up to 30 mm to match the exact valve closure point.
Press Ejection Systems
Eject massive formed parts using the 34360 N available at 0.7 MPa, relying on the 60 mm adjustable air cushions to decelerate the load smoothly.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-30S the Right Cylinder?
When sizing this unit, the 200 mm bore offers 15708 N push at 0.5 MPa for lighter frames, while this 250 mm bore reaches 24543 N for peak loads. The -30 mm adjustable window lets mechanics dial in the exact end position on-site, perfect for synchronizing shared spares across stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. The -S suffix means the piston magnet is present and ready for CMSG, DMSG or EMSG sensors. For any stroke over 500 mm, always use external guide rails to prevent side-load damage to the rod.
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 SGCJ250X450-30S FAQ
This 250 mm bore cylinder has a G1 air port and a 50 mm rod. It generates 24543 N push and 23562 N pull at 0.5 MPa, or 34360 N push and 32986 N pull at 0.7 MPa. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The nominal 450 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable range of 420 to 450 mm. The retract end remains fixed. This stop only sets the end position; it is not a load lock.
