Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X400-100S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X400-100S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 400mm 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 SGCJ125X400-100S
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore ISO 15552 tie-rod cylinder handles heavy-duty positioning with ease. Four steel tie rods clamp the aluminum barrel to the covers for structural rigidity, while the G1/2 port supplies air to the double-acting single rod. Because the -S suffix denotes a built-in piston magnet, you can mount CMSG, DMSG, or EMSG reed and electronic switches directly for end-position sensing.
The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, meaning usable travel spans 300 to 400 mm without swapping the cylinder. This on-site tuning is perfect for dialing in exact end stops, and the unit drops into existing fixtures via the ISO 15552 mounting interface. Factoring in a 2:1 safety margin, it provides a safe vertical lift capacity of roughly 313 kg, or about 3682 N of reliable working load.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X400-100S Is Used
Press Stroke Tuning
Fine-tune the extend end-position of a stamping or pressing head on-site using the 100 mm adjuster window to accommodate varying material thicknesses without changing cylinders.
Diversion Gate Stops
Adjust the extend stroke by up to 100 mm to perfectly position a pneumatic routing gate for different package sizes moving down a heavy-duty transfer line.
Pallet Lift Positioning
Lift and lower pallets with a safe working load near 3682 N, tweaking the extend stop in the field to set precise raising heights for various pallet configurations.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X400-100S the Right Cylinder?
When sizing this actuator against neighboring bores, the 125 mm sits at the lower edge of the large-bore family, offering 6136 N push at 0.5 MPa compared to 10053 N on the 160 mm. Stepping up or down lets you match exact force requirements without oversizing. The 100 mm adjustable window is highly useful when you need to share a single spare cylinder across multiple stroke variants or fine-tune a machine stop on the fly. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Since the -S magnet is present, you can fit CMSG, DMSG, or EMSG sensors. For this 400 mm stroke, always use a guide rail 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 SGCJ125X400-100S FAQ
At 0.5 MPa this 125 mm bore cylinder provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa, push increases to 8590 N and pull to 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa. It uses a G1/2 air port, features a 32 mm rod, and has 40 mm adjustable air cushions at both ends.
The nominal 400 mm stroke is the maximum travel. An external stop screw mechanism lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 300 to 400 mm. The retract end remains fixed. This adjuster sets the end position and does not lock the load; you will need an external rod lock or pilot-operated check valve to hold a load securely without live air.
