Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-20S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-20S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 300mm 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 SGCJ250X300-20S
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles heavy tasks with ease. Four steel rods clamp the aluminum barrel to the covers, and the G1 air port feeds the 50 mm rod. A built-in magnet supports CMSG, DMSG and EMSG switches for position sensing.
The external adjuster lets you shorten the extend stroke on site by up to 20 mm, giving a usable range of 280 to 300 mm without changing the cylinder itself. This on-site tuning is ideal for shared spares across stroke variants. Note that TPU seals are not offered on this 250 mm bore; NBR is standard, with a Viton H option for 0 to 150 C heat. It handles a safe working load of about 14726 N, lifting roughly 1251 kg vertically with a 2:1 margin.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-20S Is Used
Heavy Pallet Forming
Apply 24543 N of push force at 0.5 MPa to compact large pallet loads, using the 20 mm extend adjuster to tune the final press height on site.
Large Gate Actuation
Drive heavy industrial gates with the 50 mm rod, relying on the 60 mm adjustable air cushions to decelerate the 5006 kgf peak impact smoothly.
Press Positioning
Set precise stop points for heavy pressing tasks, shortening the extend stroke from 300 mm down to 280 mm to accommodate varying material thicknesses.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X300-20S the Right Cylinder?
When sizing this unit, the 160 mm bore offers 10053 N of push at 0.5 MPa for lighter jobs, while the 250 mm bore sits at the top with 24543 N. The 20 mm adjustable window helps fine-tune end positions on-site or consolidate spare parts across similar stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. The -S suffix means a magnet is installed for CMSG, DMSG or EMSG sensors. For any stroke over 500 mm, use a guide rail to prevent side-load damage to the rod seals.
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 SGCJ250X300-20S FAQ
At 0.5 MPa it provides 24543 N of push and 23562 N of pull. At 0.7 MPa the push is 34360 N and the pull is 32986 N. The theoretical maximum force is 5006 kgf at 1.0 MPa. It uses a G1 air port.
The -20 code means an external adjuster can shorten the extend stroke by up to 20 mm on site. The usable extend range is 280 to 300 mm, with 300 mm being the maximum. The retract end is fixed. This stop sets the end position but does not hold the load on air loss; use an external rod lock for that.
