Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-75S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-75S 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 SGCJ250X800-75S
Delivering massive thrust in a large-bore format, this ISO 15552 tie-rod cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. The four steel tie rods clamp the aluminum barrel securely to the covers, while the G1 port feeds the 50 mm piston rod. Because this is a 250 mm bore, TPU seals are not offered; instead it uses NBR buffer gaskets, with a Viton H option for 0 to 150 C environments.
The -75S code provides a 75 mm external adjuster window to shorten the extend stroke on site from the 800 mm maximum down to 725 mm, letting you fine-tune the end position without swapping the cylinder. The retract end remains fixed. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin. The built-in magnet supports CMSG, DMSG and EMSG sensors for position feedback.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-75S Is Used
Heavy Pallet Lifting
Raises loaded pallets in automated warehouses, using the 75 mm adjuster to set exact upper stopping heights without repositioning the frame.
Stamping Press Feed
Pushes heavy metal blanks into a large press, relying on the 24543 N thrust at 0.5 MPa and fine-tuning the extend end to match die clearance.
Bulk Material Diversion
Actuates a heavy-duty diverter arm on a high-capacity line, using the 60 mm adjustable air cushions to decelerate the massive payload smoothly.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-75S 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 need the absolute maximum 5006 kgf at 1.0 MPa. The adjustable stroke is ideal when you need on-site end-position tuning across shared spare parts, as you can dial in the 725 to 800 mm extend window precisely. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets, all dimensionally interchangeable per the ISO 15552 mounting interface. The -S suffix means a magnet is already integrated for electronic or reed switches. Because the stroke is 800 mm, always 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 SGCJ250X800-75S FAQ
This 250 mm bore cylinder features a G1 air port and a 50 mm rod. It pushes with 24543 N and pulls with 23562 N at 0.5 MPa. At 0.7 MPa, push is 34360 N and pull is 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The external stop screw lets you shorten the extend stroke on site by up to 75 mm, giving a usable extend range of 725 to 800 mm from the 800 mm nominal maximum. The retract end is fixed. This mechanism only sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve to hold a load on air loss.
