Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X25-20
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X25-20 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 25mm 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 SGCJ250X25-20
Delivering massive thrust, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. Four steel rods clamp the aluminum barrel to the covers, yielding a rigid frame that drops right into existing ISO 15552 mounting interface fixtures. It handles a safe working load of about 14726 N, which translates to lifting nearly 1251 kg vertically with a 2:1 margin.
The -20 code defines an external adjuster window that shortens the extend stroke on site by up to 20 mm. With a nominal 25 mm stroke, the usable extend range is 5 to 25 mm, letting you fine-tune the end position without swapping the cylinder. This 250 mm bore uses a G1 port, a 50 mm rod, and adjustable 60 mm cushions. Note that TPU seals are unavailable here; NBR is standard, with a Viton H option for 0-150 C heat.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X25-20 Is Used
Press Fit Tuning
Micro-adjust the 5 to 25 mm extend position on site to set precise insertion depth for heavy bearing press operations.
Stamping Depth Calibration
Dial in the exact 20 mm shortening window to regulate marking depth on thick steel plates without changing tooling.
Gate Seating Force
Apply 24543 N of force at 0.5 MPa to seat heavy industrial bulkhead valves, tweaking the closure point externally.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X25-20 the Right Cylinder?
Size this 250 mm bore against the 200 mm option, which provides 15708 N push at 0.5 MPa, or step up if you need the absolute maximum 5006 kgf at 1.0 MPa. The adjustable stroke is ideal when you need on-site end-position tuning across shared spares with slight stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this SKU lacks the -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic sensors. Even at this short 25 mm stroke, ensure external guides carry side loads to prevent binding.
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 SGCJ250X25-20 FAQ
This 250 mm bore cylinder features a G1 air port and delivers a push of 24543 N and pull of 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 -20 code means an external adjuster can shorten the extend stroke by up to 20 mm on site. The nominal 25 mm stroke is the maximum, giving a usable extend range of 5 to 25 mm. The retract end remains fixed, and this stop is for positioning only, not load holding.
