Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-75
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-75 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 SGCJ250X800-75
Delivering massive thrust for heavy industry, 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, providing structural rigidity for high-force cycles. It handles a safe working load of about 14726 N, translating to roughly 1251 kg lifted vertically with a 2:1 margin. The G1 air port feeds the 50 mm rod, which features an M42x2.0 thread and 60 mm adjustable air cushions at both ends.
The external adjuster allows you to shorten the extend stroke on-site by up to 75 mm, yielding a usable range of 725 to 800 mm. Nominal stroke is the maximum, letting you fine-tune the end position without changing the cylinder. This SKU lacks a magnet and cannot take a sensor; the -S variant is required for CMSG/DMSG/EMSG switches. Note that TPU seals are unavailable for this 250 mm bore, though Viton H raises the temperature limit to 150 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-75 Is Used
Heavy Press Tonnage
Provides raw clamping force for large metal forming presses, using the 75 mm adjuster to dial in the exact crush depth on-site.
Palletizer End Stops
Shifts heavy unit loads vertically, where the 725-800 mm extend window allows precise positioning without swapping actuators.
Stamping Pin Extraction
Pulls large industrial dies with 23562 N of retract force at 0.5 MPa, relying on the 60 mm cushions to absorb shock.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-75 the Right Cylinder?
When sizing, the 160 mm bore offers 10053 N push at 0.5 MPa, while this 250 mm bore tops out at 24543 N, making it the heavy-duty choice. The adjustable stroke helps when you need to share a spare across stroke variants or fine-tune the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a non-magnet SKU, position sensing is impossible without switching to an -S model. For the 800 mm stroke, external guides are critical to prevent rod bending and manage side loads. A plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for load holding.
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 SGCJ250X800-75 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 max is 5006 kgf at 1.0 MPa. It uses a G1 port, a 50 mm rod with an M42x2.0 thread, and 60 mm adjustable cushions. The speed range is 30-500 mm/s.
The external stop screw lets you shorten the extend stroke by up to 75 mm on-site. The usable extend range is 725 to 800 mm, with 800 mm being the maximum nominal stroke. The retract end remains fixed. This mechanism sets the end position and is not a load lock.
