Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X125-20
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X125-20 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 125mm 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 SGCJ125X125-20
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 rigidity. The G1/2 port feeds a 32 mm rod that handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin.
An external adjuster lets you shorten the extend stroke on-site by up to 20 mm, giving a usable range of 105-125 mm without changing the cylinder itself. The retract end remains fixed. This design is dimensionally interchangeable per the ISO 15552 mounting interface, and the two-way piston seal ensures reliable operation across the 30-500 mm/s speed range.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X125-20 Is Used
Press Fit Tuning
Fine-tune the 105-125 mm extend stroke on-site to dial in precise press fits without swapping cylinders or machining spacers.
Divertor Gate Stop
Adjust the end position by up to 20 mm to perfectly align a heavy divertor gate stop across varying product sizes.
Pallet Lift Cradle
Lifts roughly 313 kg vertically with a 2:1 margin, using the external adjuster to match pallet heights precisely.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X125-20 the Right Cylinder?
When sizing this 125 mm bore unit against its neighbors, it sits at the low edge of the large-bore family, offering 6136 N push at 0.5 MPa compared to the 10053 N available from the 160 mm bore. The 20 mm adjustable extend window is ideal for fine-tuning end positions on-site or sharing a spare cylinder across multiple stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a non-magnet SKU, it cannot accept CMSG, DMSG, or EMSG sensors without the -S variant. For this 125 mm stroke, side-load is minimal, but any application exceeding 500 mm requires an external guide to 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 SGCJ125X125-20 FAQ
This 125 mm bore cylinder features a G1/2 port and delivers 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 -20 code indicates an external adjuster that shortens the extend stroke by up to 20 mm on-site, giving a usable extend range of 105-125 mm while the nominal 125 mm remains the maximum. The retract end is fixed, and this stop only sets position—it does not lock the load.
