Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-50
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-50 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 700mm 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 SGCJ250X700-50
Generating massive thrust for heavy-duty automation, this large-bore ISO 15552 tie-rod cylinder outputs 24543 N of push force at 0.5 MPa. Four steel tie rods rigidly clamp the aluminum barrel to the covers, and the G1 air port feeds the Ø50 mm piston rod. Because it is a non-magnet SKU, it cannot accept CMSG or DMSG sensors without switching to the -S variant.
The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, meaning the usable extension is 650 to 700 mm while the retract end stays fixed. This lets you fine-tune the end position without physically swapping the cylinder. It handles a safe working load of roughly 14726 N, which translates to lifting about 1251 kg vertically with a 2:1 margin. Note that TPU seals are unavailable here; NBR is standard, with a Viton H option for 0 to 150 C environments.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-50 Is Used
Heavy Pallet Lift
Raises 1251 kg loaded pallets vertically using the 700 mm extend stroke, relying on the 50 mm adjuster to set the exact transfer height.
Press Tonnage Stop
Provides 24543 N of pressing force at 0.5 MPa, using the external adjuster to dial in the precise 650 mm crush depth on-site.
Multi-Bay Diverter
Pushes heavy containers into sorting lanes, fine-tuning the extend end position by up to 50 mm to clear varying door widths.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-50 the Right Cylinder?
Sizing this actuator requires looking both ways: stepping down to a 200 mm bore drops the 0.5 MPa push force to 15708 N, while this 250 mm bore maxes out the SGCJ range at 24543 N. The 50 mm adjustable window is ideal when you need to synchronize end positions across multiple fixtures or share a spare cylinder across slightly different stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the nominal stroke is 700 mm, you must provide external guide support to prevent rod bending and side-load damage. Finally, remember this plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if the load must be held.
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 SGCJ250X700-50 FAQ
At 0.5 MPa it provides 24543 N of push and 23562 N of pull. At 0.7 MPa it provides 34360 N of push and 32986 N of pull. The theoretical maximum is 5006 kgf at 1.0 MPa. The air port is G1.
The nominal stroke is 700 mm, which is the maximum extension. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, yielding a usable range of 650 to 700 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
