Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-40S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-40S 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 SGCJ250X700-40S
Delivering massive thrust with on-site flexibility, this large-bore ISO 15552 tie-rod cylinder pushes 24543 N at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the covers for structural rigidity, and the G1 pneumatic port handles high flow. An external adjuster lets you shorten the extend stroke by up to 40 mm on-site, yielding a usable 660-700 mm extension while keeping the retract end fixed.
It handles about 14726 N of real work safely, roughly 1251 kg lifted vertically with a 2:1 margin. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops into existing large-bore fixtures. The -S suffix adds a piston magnet for CMSG/DMSG/EMSG switches. Note that TPU seals are unavailable on this 250 mm bore; standard NBR seals work from -20 to +70 C, while a Viton H option extends heat resistance to 150 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-40S Is Used
Heavy Pallet Forming
Apply up to 34360 N at 0.7 MPa to compress bulky goods, using the 40 mm extend adjustment to dial in exact pallet heights on the production line.
Press Fit Tuning
Execute large bushing insertions and fine-tune the bottoming position within the 660-700 mm usable stroke window to accommodate material thickness variations.
Automated Stacking
Lift heavy unit loads vertically, relying on the 1251 kg safe lift margin, while using the magnetic piston for CMSG/DMSG/EMSG end-of-stroke confirmation.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-40S the Right Cylinder?
Size this 250 mm bore against the 200 mm option, which provides 15708 N push at 0.5 MPa, or step up if you exceed the 5006 kgf maximum. The 40 mm adjustable window is ideal for fine-tuning end positions across shared spares without machining. Mount via FA, LB, TC, FTC, TCM1, or TCM2 brackets. The built-in magnet supports CMSG/DMSG/EMSG sensors. Because the 700 mm stroke creates leverage, use external guides to prevent rod bending and manage 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 SGCJ250X700-40S FAQ
At 0.5 MPa it pushes 24543 N and pulls 23562 N. At 0.7 MPa it pushes 34360 N and pulls 32986 N. The theoretical maximum is 5006 kgf at 1.0 MPa. It uses a G1 port and a 60 mm adjustable air cushion at each end.
The nominal 700 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable 660-700 mm range. The retract end remains fixed. This stop only sets position; it does not lock the load.
