Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-30S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-30S 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 SGCJ250X80-30S
Delivering massive thrust with on-site flexibility, 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 for high structural rigidity, and the body is dimensionally interchangeable per the ISO 15552 mounting interface. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin.
The -30 code means an external adjuster can shorten the extend stroke by up to 30 mm on site, letting you fine-tune the 80 mm maximum travel down to 50 mm without changing the cylinder. The retract end is fixed. A G1 port supplies air, and the -S suffix adds a piston magnet for CMSG/DMSG/EMSG switches. Note that TPU seals are unavailable on this 250 mm bore; it uses NBR, with a Viton H option for 0-150 C environments.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-30S Is Used
Heavy Pallet Forming
Lifts heavy pallets and dunnage, using the 30 mm extend adjuster to dial in the exact raise height for different load sizes without swapping cylinders.
High-Flow Valve Actuation
Drives large process valves where the 50 to 80 mm travel window must be precisely matched to the valve disc seat on site.
Industrial Pressing
Applies up to 5006 kgf of theoretical clamping force, using the adjustable stop to set the exact crush depth for various materials.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-30S the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range, pushing 24543 N at 0.5 MPa. If you step down to a 200 mm bore, force drops to 15708 N. The adjustable stroke is ideal when you need to share one spare cylinder across slightly different stroke variants or fine-tune the end position on the machine. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2. Because this is an 80 mm stroke, side-load guide rules for strokes over 500 mm do not apply, but you should still guide the rod. The -S magnet supports CMSG/DMSG/EMSG sensors.
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 SGCJ250X80-30S FAQ
It pushes with 24543 N and pulls with 23562 N at 0.5 MPa. At 0.7 MPa, push is 34360 N and pull is 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa. It uses a G1 port and a 60 mm adjustable air cushion at each end.
The nominal 80 mm stroke is the maximum travel. An external stop screw lets you shorten the extend stroke by up to 30 mm on site, giving a usable extend range of 50 to 80 mm. The retract end is fixed. This stop sets the end position and is not a load lock; you need an external rod lock or pilot-operated check valve to hold a load on air loss.
