Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-10
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-10 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 SGCJ125X150-10
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 aluminum barrel for high structural rigidity. It is a double-acting single-rod pneumatic actuator with a 125 mm bore, a G1/2 air port, and a 40 mm adjustable air cushion at each end. The external adjuster lets you shorten the extend stroke on site by up to 10 mm, meaning the usable extend travel is 140-150 mm while the nominal 150 mm remains the maximum. This on-site tuning lets you fine-tune the end position without physically changing the cylinder. The retract end is fixed.
It handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 safety margin. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. The default TPU seal offers long life across -20 to +70 C, while a Viton H option extends this to 0-150 C. Note this specific SKU lacks a magnet and cannot take a sensor; the -S variant is required for CMSG/DMSG/EMSG switches. A plain cylinder does not hold load on air loss, as the cushion only decelerates, so use an external rod lock for suspended loads.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-10 Is Used
Press Stroke Tuning
Fine-tune the extend end position by up to 10 mm on-site to accommodate different material thicknesses in a light-duty pressing operation.
Divertor Gate Adjustment
Dial in the exact 140-150 mm gate extension needed to route varying package sizes without swapping out the entire actuator.
Vertical Lift Stop
Lift loads up to roughly 313 kg with a 2:1 margin, using the external stop screw to set precise upper travel limits on-site.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-10 the Right Cylinder?
Size this 125 mm bore against its neighbors: the larger 160 mm bore provides 10053 N push at 0.5 MPa, while this 125 mm unit delivers 6136 N. The adjustable stroke is ideal when you need to share a spare cylinder across slightly different stroke variants or fine-tune the end position on-site without machining. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because this SKU has no -S suffix, it cannot accept a magnetic sensor. Even at 150 mm stroke, verify your guide carriage to prevent excessive side loading on the 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 SGCJ125X150-10 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. This 125 mm bore cylinder uses a G1/2 air port.
The external stop screw lets you shorten the extend stroke on-site by up to 10 mm. The usable extend travel becomes 140-150 mm, with the nominal 150 mm being the maximum. The retract end is fixed, and this stop mechanism only sets end position, it does not lock the load.
