Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-20S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-20S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 450mm 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 SGCJ250X450-20S
Delivering massive thrust, this ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. The Ø250 bore uses a G1 port, a Ø50 rod and M42x2.0 thread, making it ideal for heavy-duty pressing. Four steel rods clamp the aluminium barrel for high structural rigidity.
The -20 code means an external adjuster can shorten the extend stroke on-site by up to 20 mm, giving a usable range of 430-450 mm without changing the hardware. It handles a safe working load of about 14726 N, lifting roughly 1251 kg vertically with a 2:1 margin. The -S suffix adds a piston magnet for CMSG/DMSG/EMSG sensors, while the Viton H seal option extends heat resistance to 150 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-20S Is Used
Press Fit Tuning
Fine-tune the 450 mm extend stroke down by 20 mm on-site to set the exact bottoming position for heavy bearing press fits.
Pallet Stop Calibration
Adjust the end stop externally to accommodate varying pallet heights without swapping out the entire cylinder assembly.
Heavy Clamp Positioning
Dial in the clamping reach precisely to 430 mm for oversized workpieces, using the G1 port for high-flow actuation.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-20S the Right Cylinder?
Size this against the 200 mm bore, which provides 15708 N push at 0.5 MPa, or step up if you need the full 24543 N from this 250 mm bore. The adjustable stroke is perfect for sharing spares across stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets via the ISO 15552 interface. Because the stroke is 450 mm, always use a guide rail to prevent side-load damage. The -S magnet enables position sensing.
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 SGCJ250X450-20S FAQ
At 0.5 MPa it pushes 24543 N and pulls 23562 N. At 0.7 MPa it pushes 34360 N and pulls 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The -20 code provides an external adjuster that shortens the extend stroke by up to 20 mm on-site, yielding a usable range of 430-450 mm. The nominal 450 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position but does not lock the load.
