Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-10
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-10 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 350mm 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 SGCJ250X350-10
Delivering massive thrust, 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, and the G1 port feeds the Ø50 mm rod. It handles a safe working load of about 14726 N, which means you can vertically lift roughly 1251 kg with a 2:1 safety margin.
The -10 code means an external adjuster can shorten the extend stroke on-site by up to 10 mm, giving a usable range of 340-350 mm without changing the cylinder itself. Because this is a Ø250 bore, TPU seals are unavailable; standard NBR packings handle -20 to +70 C, while a Viton H option extends heat resistance to 150 C. Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-10 Is Used
Heavy Pallet Forming
Drives large platens to compress pallets, using the 10 mm extend adjuster to dial in exact final thickness.
High-Flow Actuation
Shifts heavy industrial valves where the 34360 N push force at 0.7 MPa easily overcomes pipeline friction.
Press Ejection
Ejects dense metal parts from a mold, relying on the 60 mm adjustable air cushions to decelerate the massive load.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X350-10 the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range, offering 34360 N push at 0.7 MPa; step down to a 200 mm bore for 21991 N if you need less force. The 10 mm extend-adjustment window is ideal for fine-tuning end positions across shared spare cylinders. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. For any stroke at or over 500 mm, use a external guide to prevent side-load damage. Remember that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve to hold a load.
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 SGCJ250X350-10 FAQ
This cylinder features a G1 air port and a Ø50 mm rod. 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.
The nominal 350 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable extend range of 340-350 mm for fine position tuning. The retract end remains fixed, and the cushion only decelerates; it does not lock the load.
