Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-40
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-40 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 SGCJ250X900-40
Delivering massive thrust, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. It handles a safe working load of roughly 14726 N, which means you can vertically lift about 1251 kg with a 2:1 safety margin. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and it is dimensionally interchangeable per the ISO 15552 mounting interface.
The SGCJ250X900-40 uses a G1 air port and an external adjuster that shortens the extend stroke on site by up to 40 mm, giving a usable extend range of 860-900 mm without changing the cylinder itself. Because this is a 250 mm bore, TPU seals are not available; instead it uses NBR buffer gaskets, with a Viton H option for 0-150 C heat. Note that this specific SKU lacks a magnet and cannot take a magnetic switch, so order the -S variant if you need CMSG/DMSG/EMSG sensors.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-40 Is Used
Heavy Pallet Lifting
Raises heavy industrial pallets, using the 40 mm extend adjuster to dial in the exact upper stop height for different load sizes.
Hydraulic Press Dampening
Provides massive clamping force in large press lines, relying on the 60 mm adjustable air cushions to decelerate the heavy rod.
Automated Welding Fixtures
Positions heavy welding jigs, fine-tuning the extend end position on-site to accommodate varying workpiece geometries.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-40 the Right Cylinder?
Size this 250 mm bore against the 200 mm option, which provides 15708 N of push at 0.5 MPa, to ensure you are not over-specifying. If you need more than the 24543 N available here, no larger standard SGCJ bore exists, so you must run higher pressure up to 1.0 MPa or use multiple cylinders. The 40 mm adjustable window is ideal when you want to share one spare cylinder across several stroke variants or fine-tune the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2. Because the 900 mm stroke is long, always use an external guide to prevent rod bending and 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 SGCJ250X900-40 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. It uses a G1 port and a 50 mm rod with an M42x2.0 thread.
The external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 860-900 mm from the 900 mm nominal maximum. The retract end is fixed. This stop only sets the end position; it is not a load lock, so use an external rod lock or pilot-operated check valve to hold a load.
