Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-40
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-40 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 SGCJ250X600-40
Delivering massive thrust, this large-bore ISO 15552 tie-rod cylinder pushes with 24543 N and pulls with 23562 N at 0.5 MPa. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin. The G1 air port feeds the 50 mm piston rod, while four steel tie rods clamp the aluminium barrel to the covers for high structural rigidity.
The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 560 to 600 mm without changing the cylinder itself. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops into existing large-bore fixtures. Note this is a no-magnet SKU that cannot take a sensor, and TPU seals are unavailable on this 250 mm bore (NBR standard, Viton H for 0-150 C).

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-40 Is Used
Heavy Press Tonnage
Provides raw clamping force for hydraulic press replacement tasks, using the 40 mm adjuster to dial in the exact material crush depth on-site.
Bulk Pallet Positioning
Lifts heavy palletized goods, tweaking the extend end-position by up to 40 mm to accommodate varying load heights without swapping hardware.
Large Mold Ejection
Ejects substantial industrial molds from machines, relying on the 60 mm adjustable air cushions to safely decelerate the massive moving mass.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X600-40 the Right Cylinder?
When sizing this unit, the neighbouring 200 mm bore yields 15708 N push at 0.5 MPa, whereas this 250 mm bore hits 24543 N, placing it at the top edge of the range. The 40 mm adjustable window is ideal for sharing a spare across stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because the 600 mm stroke is long, always use external guides to prevent rod bending under side loads. Select the -S variant if you require CMSG, DMSG, or EMSG sensors, as this plain SKU cannot accept them.
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 SGCJ250X600-40 FAQ
At 0.5 MPa it pushes 24543 N and pulls 23562 N. At 0.7 MPa it pushes 34360 N and pulls 32986 N. The theoretical maximum is 5006 kgf at 1.0 MPa. This 250 mm bore unit uses a G1 air port and a 50 mm rod with an M42x2.0 thread.
The nominal 600 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable extend range of 560 to 600 mm. The retract end remains fixed. This mechanism sets the end position and is not a load lock; use an external rod lock or pilot-operated check valve to hold a load.
