Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-20
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-20 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 800mm 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 SGCJ250X800-20
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder tackles heavy industrial pressing. Four steel rods clamp the aluminum barrel, and the G1 port feeds the Ø50 mm rod. It safely handles about 14726 N of real work, lifting roughly 1251 kg vertically with a 2:1 margin.
The external adjuster lets you shorten the extend stroke by up to 20 mm on site, giving a usable range of 780 to 800 mm without changing the mount. Because TPU is unavailable on this 250 mm bore, it uses NBR seals, though a Viton H option extends heat resistance to 150 C. This non-magnet SKU cannot take a sensor; adding the -S variant enables CMSG switches.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-20 Is Used
Heavy Press Tuning
Fine-tune the 20 mm extend window on-site to set precise bottoming force without repositioning the press frame.
Pallet Positioning
Shift heavy 1251 kg vertical loads using the 800 mm stroke, adjusting the end stop to match varying pallet heights.
Mold Clamping
Clamp large injection molds securely, using the G1 port and 34360 N at 0.7 MPa to hold position during operation.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X800-20 the Right Cylinder?
Sized between the 200 mm bore (15708 N push at 0.5 MPa) and larger custom units, this 250 mm model provides 24543 N at 0.5 MPa. The 20 mm adjust window is ideal for sharing spares across stroke variants or fine-tuning end positions on-site. Mount via FA, LB, TC, FTC, TCM1, or TCM2 brackets. At 800 mm, long strokes demand external guides to prevent rod bending. Without live air, the cushion only decelerates; fit an external rod lock to hold 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 SGCJ250X800-20 FAQ
It delivers 24543 N push and 23562 N pull at 0.5 MPa, rising to 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical max of 5006 kgf at 1.0 MPa. The air port is G1.
An external stop screw shortens the extend stroke by up to 20 mm on site, yielding a usable range of 780 to 800 mm. The nominal 800 mm is the maximum, and the retract end is fixed. This stop sets position only and is not a load lock.
