Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-30S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-30S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 600mm 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 SGCJ250X600-30S
Generating up to 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles heavy-duty positioning. The four steel tie rods clamp the aluminum barrel to the covers, while the G1 air port supplies the 50 mm piston rod. A built-in magnet enables position sensing with CMSG, DMSG, or EMSG switches.
The external adjuster shortens the extend stroke by up to 30 mm on site, meaning the usable extension range is 570 to 600 mm without changing the cylinder body. It delivers a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin. The 60 mm adjustable air cushions decelerate the payload at stroke end, but an external rod lock or pilot-operated check valve is required to hold a load on air loss, as the cushion is not a brake.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-30S Is Used
Heavy Pallet Forming
Drives large platens to compress pallets, using the 30 mm extend adjuster to dial in exact 570 to 600 mm final heights on site.
Press Ejection
Pushes finished parts out of heavy presses, relying on 24543 N of thrust at 0.5 MPa and 60 mm cushions to stop the mass smoothly.
Automated Stacking
Lifts components weighing up to 1251 kg vertically with a 2:1 safety margin, using the magnet for precise height confirmation.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-30S the Right Cylinder?
This 250 mm bore sits at the top of the SGCJ range, delivering 24543 N push at 0.5 MPa compared to 15708 N from the neighboring 200 mm bore. The 30 mm adjustable extend window lets you fine-tune the end position across 570 to 600 mm on site, which is ideal for sharing spares across slightly different machine variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The included -S magnet supports CMSG, DMSG, and EMSG sensors. Because the 600 mm stroke is long, always use an external guide 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 SGCJ250X600-30S FAQ
It provides 24543 N push and 23562 N pull at 0.5 MPa, or 34360 N push and 32986 N pull at 0.7 MPa, with a theoretical max of 5006 kgf at 1.0 MPa. The air port is G1, the rod is 50 mm with an M42x2.0 thread, and it uses 60 mm adjustable cushions.
The -30 code means an external stop screw shortens the extend stroke by up to 30 mm on site. The usable extend range is 570 to 600 mm, with 600 mm being the maximum. The retract end is fixed, and the adjuster sets the end position rather than locking the load.
