Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-100
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-100 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 800mm 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 SGCJ250X800-100
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates a 100 mm external adjuster to shorten the extend stroke on site. Four steel tie rods clamp the aluminum barrel to the covers, and the G1 air port feeds a 50 mm piston rod. Because the nominal 800 mm stroke is the maximum, you can fine-tune the end position down to 700 mm without changing the hardware.
It handles a safe working load of roughly 14726 N, lifting about 1251 kg vertically with a 2:1 margin. The build is dimensionally interchangeable per the ISO 15552 mounting interface. Note that TPU seals are unavailable for this 250 mm bore; it uses NBR with a Viton H option for 0-150 C heat. This no-magnet SKU cannot take a sensor, while the -S variant supports CMSG/DMSG/EMSG switches.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-100 Is Used
Heavy Pallet Lifting
Raises heavy pallets in automated warehouses, using the 100 mm extend window to dial in exact upper stopping heights without repositioning the fixture.
Press Ejection Setup
Ejects large formed parts from heavy presses, allowing operators to shorten the extend stroke by up to 100 mm to match varying die dimensions.
Stamping Depth Control
Drives large stamping rams where the 700-800 mm usable extend range provides on-site flexibility to set precise material deformation depth.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-100 the Right Cylinder?
Size this 250 mm bore against the neighboring 200 mm class, which provides 15708 N push at 0.5 MPa. The 250 mm bore sits at the top edge with 24543 N. The 100 mm adjustable window lets you standardize one spare across multiple stroke variants, tuning the extend end precisely on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a non-magnet SKU, it cannot accept position sensors; add the -S suffix for CMSG/DMSG/EMSG compatibility. An 800 mm stroke on a large bore demands external guide rails to prevent rod bending under side loads.
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 SGCJ250X800-100 FAQ
At 0.5 MPa it delivers 24543 N push and 23562 N pull. At 0.7 MPa it outputs 34360 N push and 32986 N pull. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The external adjuster lets you shorten the extend stroke on site by up to 100 mm. The nominal 800 mm stroke is the maximum, giving a usable extend range of 700-800 mm. The retract end is fixed, and the adjuster only sets the end position; it does not lock the load.
