Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-100
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-100 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 350mm 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 SGCJ125X350-100
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 350 mm nominal stroke. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the G1/2 port feeds the double-acting single-rod piston. It is dimensionally interchangeable per the ISO 15552 mounting interface, dropping directly into existing large-bore fixtures.
The -100 code means an external adjuster can shorten the extend stroke on-site by up to 100 mm, yielding a usable extend range of 250-350 mm without changing the cylinder itself. This fine-tunes the end position perfectly, handling a safe working load of about 3682 N or lifting roughly 313 kg vertically with a 2:1 margin. Standard TPU seals offer long life, though a Viton H option extends operation to 150 C. Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-100 Is Used
Press Fit Tuning
Adjust the extend stroke on-site by up to 100 mm to set precise contact pressure on press fits without machining new spacers.
Variable Length Stops
Act as a retractable stop on a conveyor line where the required package ejection distance occasionally shifts between 250 and 350 mm.
Shared Spare Cylinder
Keep one spare cylinder in maintenance inventory and dial the stroke down from 350 mm to match various shorter-stroke units on the floor.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-100 the Right Cylinder?
Size this 125 mm bore against its neighbors: the 160 mm bore jumps to 10053 N push at 0.5 MPa, while smaller bores drop off significantly in thrust. The 100 mm adjustable window is ideal when you need to share a spare cylinder across slightly different stroke variants or fine-tune the extend end position on the machine. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a non-magnet SKU, you cannot fit position sensors; specify an -S variant if you need CMSG/DMSG/EMSG switches. For this 350 mm stroke, ensure external guide rails are used to absorb side loads and prevent rod 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 SGCJ125X350-100 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 and features a 40 mm adjustable air cushion at each end.
The 350 mm nominal stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 250-350 mm. The retract end is fixed. This mechanism sets the end position but does not lock the load; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss, as the cushion only decelerates.
