Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-50S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-50S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 80mm 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 SGCJ250X80-50S
Delivering 24543 N of thrust at 0.5 MPa, this ISO 15552 tie-rod cylinder is built for heavy-duty positioning. Four steel rods clamp the aluminum barrel to the covers, and the G1 pneumatic port feeds a 50 mm piston rod. An integrated piston magnet supports CMSG, DMSG, and EMSG sensors for precise end-position detection.
The external adjuster shortens the extend stroke by up to 50 mm on-site, letting you fine-tune the 30 to 80 mm usable travel without swapping the cylinder. It handles a safe working load of about 14726 N, lifting roughly 1251 kg vertically with a 2:1 margin. Note that TPU seals are unavailable for this 250 mm bore, which uses NBR packings, though a Viton H option extends the temperature range to 150 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-50S Is Used
Heavy Pallet Destrapping
Tuned extend stroke precisely severs steel bands on loaded pallets without striking the underlying timber deck.
Press Pin Insertion
Adjusts the 80 mm extend travel on-site to seat large-diameter pins into thick steel hubs accurately.
Bulk Valve Actuation
Provides the exact 30 to 80 mm travel required to open and close high-capacity process valves securely.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-50S the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range, offering 24543 N push at 0.5 MPa compared to 15708 N on the 200 mm bore. If your application needs less force, step down to the 200 mm option. The 50 mm adjustable window is ideal for sharing a single spare cylinder across multiple stroke variants, as you can tune the exact extend end-position on the floor. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The built-in magnet allows CMSG, DMSG, and EMSG switch integration. Because the nominal stroke is only 80 mm, side-load stress is minimal, but always guide the rod end 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 SGCJ250X80-50S FAQ
This 250 mm bore cylinder features a G1 air port and a 50 mm rod. It delivers 24543 N push and 23562 N pull at 0.5 MPa, increasing to 34360 N push and 32986 N pull at 0.7 MPa. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The nominal 80 mm extend stroke is the maximum travel. The external adjuster lets you shorten the extend stroke by up to 50 mm on-site, yielding a usable range of 30 to 80 mm. The retract end remains fixed, and this mechanism only sets the end position; it does not lock the load.
