Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-20S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-20S 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 SGCJ250X500-20S
Delivering massive thrust for heavy industry, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N of force at 0.5 MPa. Four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity, while the genuine ISO 15552 mounting interface ensures dimensional interchangeability for your existing large-bore fixtures. Air enters via a G1 port, driving a 50 mm piston rod at speeds of 30-500 mm/s.
The -20 code defines an external adjuster that lets you shorten the extend stroke on-site by up to 20 mm, giving a usable range of 480-500 mm without changing the cylinder itself. This on-site end-position tuning is invaluable for dialing in exact stops. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin. Because this is a 250 mm bore, TPU seals are unavailable; standard NBR packing handles -20 to +70 C, with a Viton H option for 0-150 C environments. The -S suffix means a built-in magnet is ready for CMSG/DMSG/EMSG sensors.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-20S Is Used
Heavy Pallet Forming
Dial in the exact 480-500 mm extend stop on-site to press heavy pallets without over-traveling, using the massive 24543 N thrust to compact materials securely.
Press Fit Tuning
Fine-tune the 20 mm extend window during assembly line commissioning to set precise bearing insertion depths, leveraging the 5006 kgf max force for stubborn components.
Automated Guided Vehicle Stops
Adjust the external stop screw to perfectly halt AGVs at loading docks, using the built-in magnet to trigger CMSG sensors for synchronized deceleration.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X500-20S the Right Cylinder?
Size this 250 mm bore against its neighbors: a 200 mm bore yields 15708 N push at 0.5 MPa, while the 250 mm bore delivers 24543 N, making it the top choice when you need extreme force. The adjustable stroke shines when you need to fine-tune end positions across multiple stations or share spares across stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The included -S magnet supports CMSG/DMSG/EMSG switches. Because the stroke is 500 mm, large-bore long strokes require external rod-end support to prevent side-load bending.
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 SGCJ250X500-20S 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. It uses a G1 port and a 50 mm rod.
The external adjuster lets you shorten the extend stroke on-site by up to 20 mm, providing a usable extend range of 480-500 mm from the 500 mm nominal maximum. The retract end is fixed. This stop only sets the end position; it does not lock the load.
