Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-50S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-50S 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 SGCJ125X100-50S
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore actuator brings precision end-position tuning to heavy pneumatic setups. The external adjuster allows you to shorten the extend stroke on-site by up to 50 mm, meaning the nominal 100 mm travel serves purely as the maximum limit while the retract end remains fixed. It handles about 3682 N of safe working load, which translates to lifting roughly 313 kg vertically with a 2:1 margin.
Built as a genuine ISO 15552 tie-rod cylinder, four steel rods clamp the aluminum barrel to the covers for high structural rigidity. The integrated -S piston magnet supports CMSG, DMSG and EMSG switches for electronic positioning, while the G1/2 port feeds the 32 mm rod. A two-way piston seal ensures reliable operation, and the standard TPU elastomer handles temperatures from -20 to +70 C, with a Viton H option extending heat resistance up to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-50S Is Used
Press Stroke Tuning
Dial in the exact 50 to 100 mm extend contact point on a light-duty assembly press without swapping the entire actuator.
Variable Length Diverters
Adjust the extend stroke on-site to accommodate different package sizes as they move down a heavy-duty sorting line.
Pallet Stop Calibration
Fine-tune the stopping position of 300 kg pallets on a roller conveyor by shortening the extend travel up to 50 mm.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-50S the Right Cylinder?
When sizing this bore, stepping down is not an option as 125 mm is the smallest in the SGCJ range, yielding 6136 N push at 0.5 MPa. Stepping up to the 160 mm bore provides 10053 N if your application demands greater thrust. The 50 mm adjustable window is highly valuable for sharing a single spare cylinder across multiple stroke variants, as you can fine-tune the extend end position mechanically on-site without changing the unit. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. Because this unit carries the -S suffix, it arrives magnet-ready for sensors. Even at 100 mm travel, always guide the load to prevent side-load wear on the rod seals.
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 SGCJ125X100-50S FAQ
This 125 mm bore cylinder pushes 6136 N and pulls 5734 N at 0.5 MPa. At 0.7 MPa it pushes 8590 N and pulls 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa. It uses a G1/2 air port and features a 32 mm piston rod.
The nominal 100 mm stroke is the maximum travel. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 50 to 100 mm. The retract end is fixed. This mechanism only sets the end position and does not lock the load; a separate rod lock or pilot-operated check valve is required for load holding.
