Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-100
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-100 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 200mm stroke, G1/2 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 SGCJ125~160 Adjustable Cylinder SGCJ125X200-100
Delivering 6136 N of push force at 0.5 MPa, this ISO 15552 tie-rod cylinder brings four steel rods and an external adjuster to large-bore pneumatics. The G1/2 port feeds a 125 mm bore that generates a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin.
The -100 code means you can shorten the extend stroke on site by up to 100 mm, dropping the usable extension to 100 mm without swapping the cylinder. Because the retract end is fixed, you simply turn the external stop screw to fine-tune the end position. This SKU lacks a magnet, so it cannot take CMSG or DMSG sensors without switching to the -S variant.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-100 Is Used
Press Fit Tuning
Dial in the exact 150 mm extend reach on site using the 100 mm adjuster window to seat bearings without over-travel.
Divertor Arm Stop
Fine-tune the push stroke to 180 mm to deflect packages precisely onto the secondary belt without re-mounting hardware.
Pallet Positioning
Shorten the extend stroke on the fly to adapt the 6136 N push force for different pallet widths at the wrapping station.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-100 the Right Cylinder?
Size this 125 mm bore against the 160 mm option if you need more power—the 160 delivers 10053 N push at 0.5 MPa, while stepping down is not possible as 125 is the smallest in the SGCJ range. The adjustable stroke shines when you share one spare cylinder across multiple stroke variants or need to dial in the extend end position on the machine. Mount it via FA, LB, TC, FTC, TCM1, or TCM2 brackets. Even at 200 mm stroke, guide the load to avoid side-loading the 32 mm rod.
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 SGCJ125~160 Adjustable Cylinder SGCJ125X200-100 FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it delivers 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. It uses a G1/2 port.
The nominal 200 mm stroke is the maximum. The external stop screw lets you shorten the extend stroke by up to 100 mm on site, giving a usable extend range of 100 to 200 mm. The retract end remains fixed, and this stop is for positioning only—it does not lock the load.
