Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-20
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-20 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 100mm 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 SGCJ125X100-20
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 -20 code means you can shorten the 100 mm extend stroke by up to 20 mm on-site, yielding a usable range of 80 to 100 mm while the retract end remains fixed. It handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin.
Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the standard TPU seals provide long service life. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. This base SKU lacks a magnet and cannot take a sensor; add the -S variant for CMSG/DMSG/EMSG switches. The G1/2 port matches the 125 mm bore, and a plain cylinder drifts on air loss, so fit an external rod lock for held loads.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-20 Is Used
Press Fit Tuning
Micro-adjust the 20 mm extend window on-site to set precise pressing force without remounting the cylinder.
Divertor Stop
Shorten the extend stroke to accommodate varying package sizes on a packaging line.
Pallet Positioning
Fine-tune the end stop to align pallets precisely before stretch wrapping.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-20 the Right Cylinder?
Size this 125 mm bore against its neighbors: the 160 mm bore yields 10053 N push at 0.5 MPa for heavier demands, while this 125 mm unit provides 6136 N push and 5734 N pull at 0.5 MPa. The adjustable stroke is ideal when you need on-site end-position tuning or want a shared spare across slightly different stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this base model lacks the -S magnet, it cannot accept position sensors. Even at 100 mm stroke, always guide the load to prevent side-load damage to the rod seal.
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 SGCJ125X100-20 FAQ
At 0.5 MPa it delivers 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical max force is 1251 kgf at 1.0 MPa. The air port is G1/2.
The 100 mm nominal stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 20 mm on-site, giving a usable extend range of 80 to 100 mm. The retract end is fixed, and this stop is for positioning only, not load holding.
