Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X100-40
The AirTAC SGCJ200-250 Adjustable Cylinder SGCJ250X100-40 is a genuine double acting, double rod, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 100mm 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 SGCJ250X100-40
Delivering massive thrust, 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 for high structural rigidity. The unit features a G1 air port, a 50 mm piston rod, and M42x2.0 rod-end threading.
The -40 code defines an external adjuster window that lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 60 to 100 mm without changing the cylinder itself. It carries genuine ISO 15552 mounting-interface interchangeability, dropping directly into existing large-bore fixtures. Note that TPU seals are not available on this 250 mm bore; it uses NBR packing, with a Viton H option for 0 to 150 C environments. This specific SKU lacks a magnet and cannot take a position sensor.

Theoretical Output Force (Ø250mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |
| 0.7 MPa | 32987 N | 32987 N |
| Max (@1.0 MPa) | 4805 kgf | |
SGCJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X100-40 Is Used
Heavy Pallet Forming
Exerts up to 34360 N at 0.7 MPa to compress bulk materials, with the 40 mm adjuster tuning the final press height precisely on the factory floor.
Large Gate Actuation
Drives heavy industrial valves using the 50 mm rod, relying on the 60 mm adjustable air cushions to decelerate the massive 5006 kgf peak load smoothly.
Stamping Press Feed
Shortens the extend stroke on-site from 100 mm down to 60 mm to synchronize part ejection timing without disassembling the ISO 15552 mounting block.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X100-40 the Right Cylinder?
If your application requires less force, step down to the 160 mm bore for 10053 N. The adjustable stroke is ideal for sharing a spare cylinder across multiple stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a no-S SKU, it cannot accept CMSG, DMSG, or EMSG sensors. For any stroke length, ensure adequate side-load guidance to prevent premature seal wear.
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 SGCJ250X100-40 FAQ
At 0.5 MPa it pushes with 24543 N and pulls with 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. It uses a G1 port, a 50 mm rod, and 60 mm adjustable air cushions at both ends.
The -40 code means an external stop screw lets you shorten the extend stroke by up to 40 mm on-site. The usable extend range is 60 to 100 mm, with the nominal 100 mm being the maximum. The retract end remains fixed. This stop only sets the end position; it does not lock the load, so you need an external rod lock or pilot-operated check valve to hold a load on air loss.
