Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-30
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-30 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 SGCJ250X80-30
Delivering massive thrust for heavy industry, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. Four steel tie rods clamp the aluminium barrel to the covers, and the unit drops into existing fixtures dimensionally interchangeable per the ISO 15552 mounting interface. It uses a G1 air port and an M42x2.0 rod thread.
The -30 code means an external adjuster can shorten the extend stroke on-site by up to 30 mm, giving a usable extend range of 50-80 mm without changing the cylinder itself. It handles a safe working load of about 14726 N, roughly 1251 kg lifted vertically with a 2:1 margin. Note this is a Ø250 bore, so TPU seals are unavailable; NBR is standard, with a Viton H option for 0-150 C heat.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-30 Is Used
Press Fit Tuning
Dial in the exact 50-80 mm insertion depth for heavy bearings on-site using the external adjuster, avoiding cylinder swaps.
Heavy Stamping
Generate up to 5006 kgf of theoretical clamping force for large metal forming operations, decelerated by 60 mm cushions.
Valve Body Seating
Apply precise, high-force end-position pressure to seat large industrial valve components securely.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-30 the Right Cylinder?
Size this 250 mm bore against the neighbouring 200 mm option, which provides 15708 N push at 0.5 MPa, or step up if you need the full 5006 kgf max theoretical force at 1.0 MPa. The adjustable stroke is ideal for fine-tuning press end positions on-site and lets you standardize one spare across slight stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this SKU lacks the -S suffix, it cannot take a magnetic switch; add -S for CMSG/DMSG/EMSG sensors. Even at this short 80 mm stroke, ensure external guides carry 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 SGCJ250X80-30 FAQ
It features a G1 air port. 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.
The nominal extend stroke is 80 mm. The -30 code provides an external stop screw that lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable range of 50-80 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve to hold a load securely.
