Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-10
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-10 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 900mm 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 SGCJ250X900-10
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 automation. The G1 air port feeds the 50 mm piston rod, which features an M42x2.0 thread and 60 mm adjustable air cushions at both ends.
The -10 code defines an external adjuster that shortens the extend stroke on-site by up to 10 mm, letting you fine-tune the end position from 890 to 900 mm without changing the cylinder itself. It handles a safe working load of roughly 14726 N, translating to about 1251 kg lifted vertically with a 2:1 margin. Because this is a 250 mm bore, TPU seals are unavailable; standard NBR packing handles -20 to +70 C, while a Viton H option extends heat resistance to 150 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-10 Is Used
Heavy Press Ejection
Punches out large stamped metal parts, using the 10 mm adjuster to dial in the exact ejection point without repositioning the cylinder.
Stamping Press Ram
Drives a heavy forming tool downward, relying on the 60 mm cushions to decelerate the massive 50 mm rod at the end of a 900 mm travel.
Pallet Diversion
Shifts loaded pallets across a heavy-duty line, fine-tuning the extend stop to accommodate slight variations in pallet width.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-10 the Right Cylinder?
Size this 250 mm bore against the neighboring 200 mm class, 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 or want to share a single spare across multiple stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. Because the 900 mm stroke is long, always use an external guide 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 SGCJ250X900-10 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.
The nominal 900 mm stroke is the maximum length. An external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable range of 890 to 900 mm for fine-tuning the end position. The retract end remains fixed.
