About the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-100S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder features a 125 mm bore and a 1000 mm stroke. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the two-way piston seal ensures reliable bidirectional operation. The G1/2 port supplies air efficiently to match the bore size.
An external adjuster allows you to shorten the extend stroke on-site by up to 100 mm, giving a usable range of 900 to 1000 mm without changing the cylinder itself. This is ideal for fine-tuning end positions across shared machine spares. The built-in -S magnet supports CMSG, DMSG and EMSG switches for position sensing. Handling a safe working load of roughly 3682 N, it can lift about 313 kg vertically with a 2:1 margin. For high-temperature environments up to 150 C, specify the Viton H seal option.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-100S Is Used
Transfer Line Diverter
Fine-tune the 1000 mm extend stop on-site by up to 100 mm to perfectly align a diverter gate without machining new mountings.
Pallet Stopper Adjustment
Accommodate varying pallet heights on a packaging line by dialing in the extend stroke window from 900 to 1000 mm as needed.
Heavy Lift Positioning
Lift loads around 313 kg vertically with a 2:1 safety margin, using the magnetic piston for precise end-of-stroke confirmation.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-100S the Right Cylinder?
When sizing this actuator, the 125 mm bore sits at the lower edge of the SGCJ large-bore family, offering 6136 N push at 0.5 MPa. If your application requires less force, consider a smaller standard cylinder, but if you need 14074 N push at 0.7 MPa, step up to the 160 mm bore. The adjustable stroke is particularly useful when you want one spare cylinder to cover multiple stroke variants by tuning the extend end position on-site. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. Because this model features a 1000 mm stroke, you must use external guides to prevent rod bending and manage side loads. The included -S magnet allows seamless integration with CMSG, DMSG or EMSG sensors.
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 SGCJ125X1000-100S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. The air port size is G1/2.
The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, providing a usable extend range of 900 to 1000 mm. The nominal 1000 mm stroke is the maximum, and the retract end remains fixed. Note that a plain cylinder does not hold load without live air; use an external rod lock or pilot-operated check valve for load holding.
