Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-50
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-50 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 150mm 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 SGCJ125X150-50
Delivering 6136 N of push force at 0.5 MPa, this ISO 15552 tie-rod cylinder brings large-bore power to tasks needing precise end-position tuning. Four steel tie rods clamp the aluminum barrel to the covers, and the G1/2 port feeds the 32 mm rod. An external adjuster lets you shorten the extend stroke by up to 50 mm right at the machine, meaning the 150 mm nominal stroke serves as your maximum travel while the retract end stays fixed. This on-site tuning avoids swapping cylinders for minor length changes.
The mechanism sets the end position but is not a load lock, so fit an external rod lock or pilot-operated check valve if you need to hold a vertical load against gravity. The standard TPU seals handle -20 to +70 C, while the Viton H option extends that to 0-150 C. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors. In practice, it safely handles about 3682 N of real work, which translates to lifting roughly 313 kg vertically with a 2:1 margin.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-50 Is Used
Press Fit Tuning
Fine-tune the 150 mm extend stroke by up to 50 mm on-site to dial in the exact seating depth for bearing or bushing press fits without machining new stops.
Divertor Gate Adjustment
Adjust the extend endpoint externally to change a divertor gate angle on the fly, accommodating different package sizes on the same line.
Pallet Stop Calibration
Shorten the extend stroke by the 50 mm window to calibrate pallet stop positions precisely during equipment changeovers.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-50 the Right Cylinder?
When sizing this 125 mm bore, stepping down is not an option as it is the smallest in the SGCJ range, but stepping up to the 160 mm bore increases push force at 0.5 MPa to 10053 N. The 50 mm adjustable window is highly useful when you want a shared spare across multiple stroke variants or need to fine-tune the extend end position without changing the cylinder body. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Since this specific SKU has no -S magnet, it cannot accept position sensors; add the -S suffix if you require CMSG, DMSG, or EMSG switches. Although 150 mm is under the 500 mm side-load threshold, always guide the rod to prevent 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 SGCJ125~160 Adjustable Cylinder SGCJ125X150-50 FAQ
This 125 mm bore cylinder uses a G1/2 port. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa.
The 150 mm nominal stroke is the maximum travel. The external adjuster lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 100-150 mm. The retract end remains fixed, and this adjuster sets the end position rather than locking the load.
