Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-10
The AirTAC SGCJ200-250 Adjustable Cylinder SGCJ250X80-10 is a genuine double acting, double rod, 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 SGCJ250X80-10
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 environments.
The -10 code defines a 10 mm external adjuster window that shortens the extend stroke on site, letting you set a usable extend range of 70-80 mm without changing the cylinder itself. The retract end remains fixed. This design is dimensionally interchangeable per the ISO 15552 mounting interface, dropping directly into existing large-bore fixtures. Note this SKU lacks a magnet and cannot take a sensor; the -S variant is required for CMSG/DMSG/EMSG switches.

Theoretical Output Force (Ø250mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |

SGCJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-10 Is Used
Heavy Valve Actuation
Actuate large industrial valves with a 50 mm rod and G1 port, using the 10 mm adjuster to set precise closure limits on-site.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-10 the Right Cylinder?
The adjustable stroke is ideal when you need to fine-tune the extend end position on-site or share a spare cylinder across slightly different short-stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. Even at this 80 mm stroke, guide the load to prevent side-load wear on the rod. Since this non-S SKU has no magnet, you cannot mount position 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 SGCJ250X80-10 FAQ
The theoretical max is 5006 kgf at 1.0 MPa. It features a 50 mm rod, M42x2.0 rod thread, G1 port, and 60 mm adjustable air cushions at both ends.
The 80 mm nominal stroke is the maximum. The external -10 adjuster lets you shorten the extend stroke by up to 10 mm on-site, giving a usable extend range of 70-80 mm. The retract end is fixed. This mechanism only sets the end position; it does not lock the load.
