Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-40
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-40 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 160mm 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 SGCJ125X160-40
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses four steel rods to clamp its aluminium barrel for high structural rigidity. A two-way piston seal and the G1/2 port ensure reliable airflow, while the external adjuster allows you to shorten the extend stroke on-site by up to 40 mm without changing the unit itself.
The nominal 160 mm stroke remains the maximum, yielding a usable 120 to 160 mm extend window with a fixed retract end. It handles a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 margin. A Viton H seal option can extend the operating temperature up to 150 C, and since this specific SKU lacks a magnet, it cannot accept magnetic switches without switching to the -S variant.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-40 Is Used
Press Fit Tuning
Micro-adjust the 40 mm extend window on-site to set precise bottoming pressure for pressing bearings without remounting the cylinder.
Transfer Diverter
Dial in the exact extend stop position to deflect parts onto secondary packaging lines while accommodating varying product widths.
Pallet Stopper Gate
Regulate the extend stroke to act as a fixed-height pallet stop, allowing quick field changes when pallet dimensions vary.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-40 the Right Cylinder?
When sizing this 125 mm bore, stepping down is not an option as it is the smallest in the SGCJ family, but stepping up to the 160 mm bore raises the 0.5 MPa push force to 10053 N if your application demands more power. The 40 mm adjustable window is ideal for fine-tuning end positions on-site or sharing a single spare cylinder across multiple stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this non-magnet SKU cannot host a sensor, you must select the -S version if your circuit requires CMSG, DMSG, or EMSG switches. For this 160 mm stroke, standard guide tolerances apply, but any future deployment exceeding 500 mm will require external load guides to prevent side-loading damage.
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 SGCJ125X160-40 FAQ
This 125 mm bore cylinder uses a G1/2 air port and generates 6136 N push and 5734 N pull at 0.5 MPa. 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 external adjuster lets you shorten the extend stroke by up to 40 mm on-site, giving a usable extend range of 120 to 160 mm. The nominal 160 mm stroke is the maximum, and the retract end remains fixed. This mechanism only sets the end position and does not lock the load.
