Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-100
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-100 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 SGCJ125X160-100
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster to fine-tune the extend end position without changing your mounting. The SGCJ125X160-100 uses a 100 mm on-site shortening window, meaning the usable extend stroke shrinks from the 160 mm maximum down to 60 mm while the retract end stays fixed. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the two-way piston seal ensures reliable bidirectional operation. Threaded to a G1/2 port, it handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 safety margin.
This double-acting single-rod unit is dimensionally interchangeable per the ISO 15552 mounting interface, dropping easily into existing large-bore fixtures. It features adjustable 40 mm air cushions at both ends to absorb kinetic energy near the stroke limits. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic sensors. Furthermore, the cushion only decelerates the piston; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a load securely.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-100 Is Used
Press Stroke Tuning
Dial in the exact 60 to 160 mm extend position on a light-duty stamping press without machining new spacers or swapping the cylinder body.
Variable Length Diverter
Adjust the extend reach of a package routing gate on the fly to accommodate different box sizes on a shared conveyor line.
Adjustable Stop Gate
Set a precise physical stop position for pallets entering a wrapping station, fine-tuning the 100 mm window to match pallet depth variations.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-100 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 moving up to the 160 mm bore increases the 0.5 MPa push force substantially to 10053 N. The 100 mm adjustable window is highly beneficial for sharing a single spare cylinder across multiple machines that require slightly different extend lengths from 60 to 160 mm. Standard mounting attachments include FA, LB, TC, FTC, TCM1, and TCM2 styles. Since this is a non-magnetized version, order an -S variant if your application requires position sensing. Although the 160 mm stroke is relatively short, always ensure adequate side-load guidance to prevent premature seal wear on the 32 mm piston 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 SGCJ125X160-100 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 32 mm piston rod with an M27x2.0 rod-end thread.
The nominal 160 mm stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 60 to 160 mm. The retract end position remains fixed. This mechanism only sets the end position and does not lock the load.
