Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-20S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-20S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 700mm 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 SGCJ250X700-20S
Delivering massive thrust for heavy industry, this ISO 15552 tie-rod cylinder pushes with 24543 N at 0.5 MPa. The four steel tie rods clamp the aluminium barrel securely to the covers, yielding high rigidity for demanding cycles. Because it is a large 250 mm bore, the port is G1 and TPU seals are not offered; instead it uses NBR packings, with a Viton H option for 0 to 150 C environments. A built-in magnet (-S) supports CMSG, DMSG and EMSG sensors for position detection.
The -20 code means an external adjuster can shorten the extend stroke on site by up to 20 mm, letting you fine-tune the end position from 680 to 700 mm without changing the cylinder itself. This yields a safe working load of roughly 14726 N, or about 1251 kg lifted vertically with a 2:1 margin. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-20S Is Used
Heavy Pallet Lifts
Raises loaded pallets in automated warehouses, using the 20 mm extend adjuster to set precise stopping heights without repositioning the frame.
Press End Tuning
Drives large forming presses where the on-site stroke reduction dials in the exact contact point for varying material thicknesses.
Stamping Clamps
Secures heavy steel plates in stamping lines, leveraging the 60 mm adjustable air cushions to decelerate massive moving masses smoothly.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-20S the Right Cylinder?
Size this 250 mm bore against the neighbouring 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 20 mm adjustable window is ideal for sharing a spare cylinder across similar stroke variants or dialing in the exact end position on site. Mounting choices include FA, LB, TC, FTC, TCM1 and TCM2. The -S suffix ensures you have the magnet required for CMSG, DMSG or EMSG switches. Because the 700 mm stroke is long, always provide external guide rails to prevent rod bending under side loads.
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 SGCJ250X700-20S FAQ
This 250 mm bore cylinder features a G1 air port and an M42x2.0 rod thread. It delivers 24543 N push and 23562 N pull at 0.5 MPa, 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical maximum force of 5006 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 20 mm on site, giving a usable extend range of 680 to 700 mm while the retract end remains fixed. This mechanism only sets the end position; it does not lock the load, so you need an external rod lock or pilot-operated check valve to hold a load without live air.
