Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X550-30S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X550-30S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 550mm 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 SGCJ250X550-30S
Generating 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder features a 250 mm bore and a 550 mm stroke. The external adjuster allows you to shorten the extend stroke on-site by up to 30 mm, yielding a usable range of 520 to 550 mm without changing the cylinder itself. A G1 port handles the air supply, while four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity.
The built-in piston magnet supports CMSG, DMSG, and EMSG switches for precise position detection. Because this is a 250 mm bore, TPU seals are unavailable, but NBR packing handles standard -20 to +70 C environments, with a Viton H option for 0-150 C heat. This actuator handles a safe working load of roughly 14726 N, translating to lifting about 1251 kg vertically with a 2:1 margin. Note that the 60 mm adjustable air cushions only decelerate the piston near the end caps; they do not hold the load on air loss, so use an external rod lock or pilot-operated check valve for static holding.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X550-30S Is Used
Heavy Pallet Lifting
Lifts heavy palletized loads up to 1251 kg vertically with a 2:1 safety margin, utilizing the 30 mm on-site stroke adjuster to precisely set the upper stopping height.
Press Ejection Station
Ejects finished parts from large presses using 24543 N of thrust, relying on the 60 mm adjustable air cushions to smoothly decelerate the 50 mm rod at stroke end.
Automated Guided Vehicle Stops
Acts as a heavy-duty physical stop mechanism for AGVs, where the G1 port and tie-rod rigidity endure repeated high-mass impacts in busy logistics hubs.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X550-30S the Right Cylinder?
When sizing this actuator, stepping down to a 200 mm bore yields 15708 N of push at 0.5 MPa, whereas this 250 mm bore delivers 24543 N, and it remains the largest available option in the SGCJ family. The 30 mm adjustable window is highly useful for synchronizing end positions across multiple fixtures or sharing spares across stroke variants, as you can fine-tune the extend stop on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets, all conforming to ISO 15552 mounting-interface dimensions. The -S suffix confirms the magnet is present for sensors. Because the 550 mm stroke is relatively long for a large-bore actuator, ensure adequate rod-end support and external guiding 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 SGCJ250X550-30S 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, 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 lets you shorten the extend stroke on-site by up to 30 mm. The nominal 550 mm stroke is the maximum, giving a usable extend range of 520 to 550 mm, while the retract end remains fixed. This mechanism sets the end position and is not a load lock.
