Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-40S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-40S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 900mm 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 SGCJ250X900-40S
Generating massive thrust, this large-bore ISO 15552 tie-rod cylinder outputs 24543 N of push force at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the covers, delivering structural rigidity for heavy-duty automation. A built-in piston magnet supports CMSG, DMSG, and EMSG sensors for position detection.
The -40 code defines an external adjuster that shortens the extend stroke on site by up to 40 mm, yielding a usable range of 860 to 900 mm while the retract end remains fixed. This lets you fine-tune the end position without physically changing the cylinder. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops into existing large-bore fixtures. It handles a safe working load of roughly 14726 N, translating to about 1251 kg lifted vertically with a 2:1 margin. Pneumatic supply connects via a G1 port, and the NBR seals accommodate temperatures from -20 to +70 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-40S Is Used
Heavy Pallet Lifting
Elevates 1200 kg pallets in automated distribution hubs, using the 40 mm adjuster to precisely set the lift height to match varying dock levels.
Press Ejection
Clears large finished parts from hydraulic presses, relying on the 60 mm adjustable air cushions to decelerate the 50 mm rod smoothly at the end of a 900 mm travel.
Automated Storage
Actuates heavy shelving carriages in high-bay warehouses, benefiting from the ISO 15552 mounting interface for straightforward fixture integration.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-40S the Right Cylinder?
When sizing this actuator, the neighboring 200 mm bore provides 15708 N of push at 0.5 MPa, whereas this 250 mm bore delivers 24543 N, establishing the upper limit of the SGCJ range. The adjustable stroke is ideal for sharing a single spare cylinder across multiple stroke variants or fine-tuning end positions during machine commissioning. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the -S suffix denotes a magnet, it directly accepts CMSG, DMSG, and EMSG switches. At a 900 mm stroke, the large bore generates significant rod bending moments; always provide external guide rails to support side loads and 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 SGCJ250X900-40S FAQ
At 0.5 MPa it provides 24543 N of push and 23562 N of pull. 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. Air connects via a G1 port.
The 900 mm stroke is the maximum travel. An external stop screw lets you shorten the extend stroke on site by up to 40 mm, giving a usable extend range of 860 to 900 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock.
