Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-10S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-10S 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 SGCJ250X900-10S
Delivering massive thrust for heavy industry, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. The four steel tie rods clamp the aluminium barrel securely to the covers, while the G1 port handles the high air volume needed for the 250 mm bore. An external adjuster lets you shorten the extend stroke on-site by up to 10 mm, meaning the 900 mm nominal stroke serves as a maximum and the retract end remains fixed. This allows fine-tuning of the end position without physically changing the cylinder.
For practical sizing, expect a safe working load around 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 safety margin. The included -S magnet supports CMSG, DMSG and EMSG switches for precise position detection. Note that TPU seals are unavailable for this bore; NBR is standard, though a Viton H option extends the temperature range from 0 to 150 C. The 60 mm adjustable air cushions at each end decelerate the heavy piston smoothly, but remember a plain cylinder drifts without live air—use an external rod lock for held loads.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-10S Is Used
Heavy Stamp Press Ejection
Ejects large formed panels from a 2000-ton press, using the 10 mm extend adjuster to dial in the exact hand-off position without repositioning the heavy die.
Automated Pallet Lift Gate
Raises loaded 1000 kg pallets on a conveyor junction, relying on the 60 mm adjustable air cushions to safely stop the massive 250 mm piston at the top of its 900 mm travel.
Large Pipe Bending Stop
Acts as a positive end-stop for thick steel pipe feeding into a bender, fine-tuning the cut length on-site via the external adjuster while tracking position with EMSG sensors.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-10S the Right Cylinder?
When sizing this unit, the 250 mm bore sits at the top of the SGCJ range, pushing 24543 N at 0.5 MPa. If your application is lighter, stepping down to a 200 mm bore drops the push force to 15708 N while saving significant physical space and air volume. The adjustable 10 mm extend window is highly useful when you need to share a spare cylinder across multiple stroke variants or fine-tune the end position on-site without machining. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets, all conforming to the ISO 15552 mounting interface for easy fixture interchange. Because the 900 mm stroke is long, always provide external rod-end support to prevent side-loading and rod bending under such high forces.
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 SGCJ250X900-10S 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.
The external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable extend range of 890 to 900 mm. The nominal 900 mm stroke is the maximum, and the retract end is fixed. This mechanism sets the end position and is not a load lock.
