Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-40S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-40S 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 SGCJ250X80-40S
Delivering massive thrust for heavy industry, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. The four steel rods clamp the aluminium barrel to the covers for maximum rigidity, while the genuine ISO 15552 mounting interface ensures dimensional interchangeability with standard large-bore fixtures. A built-in piston magnet supports CMSG, DMSG and EMSG switches for precise position detection.
The -40 code means an external adjuster can shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 40 to 80 mm without changing the cylinder. This on-site tuning is ideal for dialling in exact end positions. The G1 port and M42x2.0 rod thread handle high flow, and the 60 mm adjustable air cushions absorb heavy impact. Handling about 14726 N of real work, it can lift roughly 1251 kg vertically with a 2:1 margin. Note that TPU seals are unavailable for this 250 mm bore; NBR is standard, with a Viton H option for 0 to 150 C environments.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-40S Is Used
Press Pinning
Dial in the exact 40 to 80 mm extend depth on-site to seat heavy bearings without swapping cylinders.
Pallet Stopping
Use the massive 34360 N push force at 0.7 MPa to halt loaded pallets, fine-tuning the stop position by 40 mm.
Gate Actuation
Adjust the external stop to set precise valve opening distances, relying on the 60 mm cushions to absorb fluid shocks.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-40S the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range, delivering 24543 N push at 0.5 MPa. If you do not need this full power, stepping down to the 200 mm bore drops the push force to 15708 N while saving space. The adjustable stroke is a major selection advantage here: because the extend end position can be fine-tuned by up to 40 mm on-site, you can standardise on this single 80 mm nominal unit across multiple machines and simply dial in the exact 40 to 80 mm travel required. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2. The -S suffix means the magnet is present and ready for sensors. Even at this short 80 mm stroke, always guide the load to prevent side-load damage.
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 SGCJ250X80-40S 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. This 250 mm bore cylinder uses a G1 air port and an M42x2.0 piston rod thread.
The nominal stroke is 80 mm, which is the maximum extend travel. The external -40 adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 40 to 80 mm. The retract end is fixed. This stop only sets the end position; it does not lock the load, so use an external rod lock for holding.
