Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-100S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-100S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 80mm 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 SGCJ250X80-100S
Delivering massive thrust in a heavy-duty format, this large-bore ISO 15552 tie-rod cylinder uses four steel rods to clamp its aluminium barrel securely to the end covers. The double-acting single-rod design generates 24543 N of push force and 23562 N of pull force at 0.5 MPa, while the G1 air port feeds the 50 mm piston rod. Because this is a 250 mm bore unit, the standard TPU seal is unavailable, but an NBR front-cover packing handles the -20 to +70 C range, and a Viton H option extends heat resistance up to 150 C.
The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, meaning the 80 mm nominal stroke represents the maximum extension. You can fine-tune the end position without physically changing the cylinder. This model includes a built-in piston magnet for CMSG, DMSG, and EMSG sensors. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 safety margin.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-100S Is Used
Press Fit Tuning
Micro-adjust the 100 mm extend window on-site to set precise insertion depths for heavy bearing assemblies without swapping physical spacers.
Stamping Depth Control
Leverage the 24543 N push force to form thick plate steel, dialing in the exact stroke end position to control material deformation.
Heavy Clamping
Secure large fabricated weldments for machining, using the 50 mm rod and massive 5006 kgf maximum force to hold parts rigidly.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X80-100S the Right Cylinder?
When sizing this unit, stepping down to a 200 mm bore drops the 0.5 MPa push force to 15708 N, whereas this 250 mm bore provides 24543 N. The adjustable stroke is highly useful for sharing one spare cylinder across multiple stroke variants, as you can tune the extend end position on-site. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. The included -S magnet supports reed and electronic position sensing. Even at this short 80 mm stroke, always ensure external guides carry side loads to prevent rod binding.
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 SGCJ250X80-100S FAQ
At 0.5 MPa it provides 24543 N push and 23562 N pull. At 0.7 MPa it provides 34360 N push and 32986 N pull. The theoretical maximum force is 5006 kgf at 1.0 MPa. It features a 50 mm rod, a G1 air port, an M42x2.0 rod thread, and 60 mm adjustable air cushions at both ends.
The 80 mm nominal stroke is the maximum extension. The external stop screw lets you shorten the extend stroke on-site by up to 100 mm, allowing you to set the end position anywhere down to zero. The retract end remains fixed. This mechanism only sets the end position; it does not lock the load.
