Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-75
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-75 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 SGCJ250X700-75
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 G1 air port feeds the 50 mm piston rod, generating a safe working load of roughly 14726 N. That translates to lifting about 1251 kg vertically with a 2:1 safety margin.
An external adjuster lets you shorten the extend stroke on site by up to 75 mm, giving a usable range of 625 to 700 mm without changing the cylinder itself. The retract end remains fixed. Because this is a 250 mm bore, TPU seals are unavailable, but NBR packing handles standard -20 to +70 C duties, with a Viton H option for 0-150 C heat. This non-magnet SKU lacks the -S option and cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-75 Is Used
Heavy Press Tonnage
Supplies up to 34360 N of extend force at 0.7 MPa for forming heavy-gauge metal panels, using the 75 mm adjuster to tune the exact bottom-dead-center position.
Pallet Lift Positioning
Raises loaded pallets vertically, safely managing around 1251 kg with a 2:1 margin, while the 60 mm adjustable air cushions decelerate the payload smoothly.
Large Mold Ejection
Ejects substantial injection molds from shared fixtures, allowing on-site stroke shortening from 700 mm down to 625 mm to accommodate varying mold heights.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-75 the Right Cylinder?
Size this 250 mm bore against the 200 mm option, which provides 15708 N of push at 0.5 MPa, or step up if you need the absolute maximum 5006 kgf at 1.0 MPa. The 75 mm adjustable window is ideal for fine-tuning end positions across multiple fixtures or sharing a spare cylinder across stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets, all conforming to ISO 15552 interface dimensions. With a 700 mm stroke, you must use external guide rails to prevent rod bending and absorb side loads. Remember that air cushions only decelerate the piston; use an external rod lock or pilot-operated check valve to hold a load securely on air loss.
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 SGCJ250X700-75 FAQ
At 0.5 MPa it pushes with 24543 N and pulls with 23562 N. 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.
The external adjuster lets you shorten the extend stroke on site by up to 75 mm. The usable extend range is 625 to 700 mm, with 700 mm being the maximum nominal stroke, while the retract end remains fixed.
