Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-20
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-20 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 SGCJ250X700-20
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster that shortens the extend stroke on-site by up to 20 mm. The nominal 700 mm stroke remains the maximum travel, yielding a usable 680 to 700 mm window for fine-tuning the end position without changing the hardware. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the G1 air port feeds the 50 mm rod.
This double-acting single-rod unit handles a safe working load of roughly 14726 N, which translates to lifting about 1251 kg vertically with a 2:1 safety margin. The 60 mm adjustable air cushions at both ends absorb kinetic energy near stroke end, while the NBR seals operate from -20 to +70 C (Viton H raises this to 150 C). Note that TPU seals are unavailable on this 250 mm bore, and this specific SKU lacks a magnet so it cannot take CMSG, DMSG or EMSG sensors.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-20 Is Used
Heavy Pallet Lifting
Raises loaded pallets in automated distribution hubs, using the 20 mm adjuster to dial in the exact upper stop height for different pallet sizes.
Press Ejection Systems
Ejects heavy formed parts from large presses, relying on the 60 mm cushions to decelerate the 50 mm rod smoothly at the end of a 700 mm travel.
Stamping Positioning
Feeds thick steel blanks into stamping stations, tweaking the extend position on-site by up to 20 mm to align the material without reworking fixtures.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X700-20 the Right Cylinder?
When sizing this unit, the 160 mm bore offers 10053 N push at 0.5 MPa for lighter jobs, while the 250 mm bore sits at the top edge with 24543 N. The 20 mm external adjuster is ideal when you need to share a spare cylinder across slightly different stroke variants or fine-tune the extend end position on-site. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets via the ISO 15552 mounting interface. Because this is a 700 mm stroke, you must use external guides to prevent rod bending and side loads. To add position sensing, select the -S magnet variant for CMSG, DMSG or EMSG switches.
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 SGCJ250X700-20 FAQ
At 0.5 MPa it provides 24543 N push and 23562 N pull. At 0.7 MPa it delivers 34360 N push and 32986 N pull. The theoretical maximum force is 5006 kgf at 1.0 MPa. It uses a G1 air port and a 50 mm piston rod.
The external adjuster lets you shorten the extend stroke on-site by up to 20 mm. The nominal 700 mm stroke is the maximum, giving a usable extend range of 680 to 700 mm, while the retract end remains fixed. This mechanism sets the end position and is not a load lock.
