Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-40
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-40 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 75mm 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 SGCJ250X75-40
Generating up to 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles heavy-duty positioning with precision. The four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity, while the G1 port feeds the 50 mm piston rod. It delivers a safe working load of about 14726 N, capable of lifting roughly 1251 kg vertically with a 2:1 margin.
The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 35 to 75 mm without changing the cylinder itself. This SKU lacks a magnet and cannot take a sensor; adding the -S variant enables CMSG/DMSG/EMSG switches. Note that TPU seals are unavailable on this 250 mm bore, though Viton H raises the temperature limit to 0-150 C.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-40 Is Used
Press Stroke Calibration
Fine-tune the 35 to 75 mm extend distance on-site to set precise stamping depth without swapping the cylinder.
Heavy Pallet Stopping
Use the 24543 N push force at 0.5 MPa to halt loaded pallets, adjusting the stop position by up to 40 mm.
Clamp Position Trimming
Dial in the exact clamping reach on heavy fixtures using the external adjuster to shorten the extend stroke.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X75-40 the Right Cylinder?
When sizing this unit against its neighbors, the 200 mm bore provides 15708 N push at 0.5 MPa, while this 250 mm bore jumps to 24543 N. The 40 mm adjustable window is ideal for sharing a spare cylinder across multiple stroke variants or fine-tuning the end position during machine commissioning. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a no-S SKU, it cannot accept magnetic sensors. Even at 75 mm stroke, ensure external guide rails support any 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 SGCJ250X75-40 FAQ
This 250 mm bore cylinder features a G1 port and generates 24543 N push and 23562 N pull at 0.5 MPa. At 0.7 MPa it delivers 34360 N push and 32986 N pull. The theoretical maximum force is 5006 kgf at 1.0 MPa.
The external stop screw lets you shorten the extend stroke on-site by up to 40 mm from the 75 mm nominal maximum, yielding a usable extend range of 35 to 75 mm. The retract end remains fixed, and this stop only sets the end position; it is not a load lock.
