Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-10S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-10S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 80mm 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 SGCJ250X80-10S
Generating a massive 24543 N of push force at 0.5 MPa, this 250 mm bore ISO 15552 tie-rod cylinder handles heavy-duty positioning with ease. The four steel tie rods clamp the aluminum barrel securely, and the G1 air port feeds the 50 mm piston rod. Because this is a -S model, a built-in piston magnet supports CMSG, DMSG, or EMSG switches for precise end-of-stroke detection.
The -10 code means an external adjuster can shorten the extend stroke on site by up to 10 mm, giving a usable extend range of 70 to 80 mm without changing the cylinder itself. This on-site fine-tuning is ideal for dialing in exact end positions. It delivers a safe working load of about 14726 N, which means it can lift roughly 1251 kg vertically with a 2:1 margin. Note that TPU seals are not offered on this 250 bore; NBR is standard, with a Viton H option for 0 to 150 C environments.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-10S Is Used
Heavy Pallet Clamping
Dial in the exact 70 to 80 mm clamping reach on-site to secure heavy pallets without over-traveling and crushing the load.
Press End-Stop Tuning
Fine-tune the final 10 mm of the extend stroke on a heavy press to accommodate different material thicknesses quickly.
Heavy Lift Positioning
Lift loads up to 1251 kg vertically and use the external adjuster to set the precise discharge height at various conveyor stations.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-10S the Right Cylinder?
As the largest bore in the SGCJ range, this 250 mm cylinder sits at the high edge, offering 24543 N push at 0.5 MPa compared to 15708 N on the 200 mm bore. If your application needs less force, stepping down saves space and air. The adjustable stroke feature is highly useful when you need to share a spare cylinder across slightly different stroke variants or fine-tune the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The included -S magnet allows for electronic or reed sensor tracking. Even at this short 80 mm stroke, always guide the rod to prevent side-load wear.
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 SGCJ250X80-10S FAQ
At 0.5 MPa it provides 24543 N push and 23562 N pull. At 0.7 MPa it delivers 34360 N push and 32986 N pull. The theoretical max force is 5006 kgf at 1.0 MPa. This 250 mm bore cylinder uses a G1 air port and features a 50 mm rod with an M42x2.0 thread.
The 80 mm nominal stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable range of 70 to 80 mm. The retract end is fixed. This adjuster sets the end position and is not a load lock; for holding loads on air loss, use an external rod lock or pilot-operated check valve.
