Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-30
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-30 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 500mm 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 SGCJ250X500-30
Delivering massive thrust for heavy industry, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity. The G1 air port feeds the 50 mm rod, yielding a safe working load around 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin.
The -30 code defines an external adjuster that shortens the extend stroke on site by up to 30 mm. You can fine-tune the end position from 470 to 500 mm without changing the cylinder, while the retract end remains fixed. It uses NBR seals because TPU is unavailable on this 250 mm bore, though a Viton H option raises heat resistance to 150 C. Note this SKU lacks a magnet and cannot take a sensor.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-30 Is Used
Press Stroke Tuning
Micro-adjust the 30 mm extend window on a metal stamping press to set precise bottom-dead-center without physically shimming the tool.
Heavy Platen Lowering
Safely lowers a 1200 kg platen using adjustable air cushions, tweaking the final landing position on the fly to match varying material heights.
Pallet Stopper Gate
Acts as a heavy-duty stop gate in a high-mass conveyor line, using the on-site adjuster to accommodate different pallet depths quickly.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-30 the Right Cylinder?
When sizing this unit, the smaller 200 mm bore offers 15708 N push at 0.5 MPa, whereas this 250 mm bore tops out at 24543 N. The adjustable stroke is ideal for sharing spares across stroke variants or tuning end positions on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the stroke is 500 mm, add external guides to prevent rod bending under side loads. Choose the -S variant if you need CMSG or DMSG 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 SGCJ250X500-30 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 external stop screw lets you shorten the extend stroke by up to 30 mm on site, giving a usable range of 470 to 500 mm. The nominal 500 mm stroke is the maximum, and the retract end is fixed. This mechanism sets the end position and is not a load lock.
