Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-30
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-30 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1000mm 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 SGCJ125X1000-30
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles heavy duty automation with ease. Four steel tie rods clamp the aluminum barrel to the covers for structural rigidity, while the two-way piston seal ensures reliable bidirectional operation. It provides a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin. The G1/2 port feeds the 125 mm bore chamber efficiently.
The -30 code defines a 30 mm external adjuster window, letting you shorten the extend stroke on-site from the 1000 mm maximum down to 970 mm without changing the cylinder itself. The retract end remains fixed. This design is dimensionally interchangeable per the ISO 15552 mounting interface, dropping into existing large-bore fixtures seamlessly. For high-heat environments up to 150 C, you can specify the Viton H seal option instead of the standard TPU.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-30 Is Used
Stopper Cylinder Tuning
Acts as an adjustable stopper on a heavy transfer line, using the 30 mm window to fine-tune the 1000 mm extend position so diverse pallet lengths index correctly without swapping hardware.
Long-Stroke Press Feed
Pushes bulk material into a forming press, where the on-site adjuster dials in the exact 970 to 1000 mm feed length to compensate for material thickness variations.
Heavy Payload Escapement
Separates large castings on a gravity conveyor, relying on the 6136 N thrust at 0.5 MPa to index parts while the external stop screw sets the precise release point.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-30 the Right Cylinder?
When sizing this unit, the 125 mm bore sits at the low edge of the SGCJ family, offering 6136 N push at 0.5 MPa; stepping up to the 160 mm bore yields 10053 N if your payload increases. Conversely, if you need significantly more force, the 250 mm bore provides 24543 N. The adjustable stroke is ideal for sharing a single spare cylinder across multiple stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a no-S SKU, it cannot take a magnetic switch; you must select the -S variant for CMSG/DMSG/EMSG sensor compatibility. At 1000 mm of stroke, large-bore rods are prone to bending under side loads, so an external guide and rod-end support are mandatory.
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 SGCJ125X1000-30 FAQ
This 125 mm bore cylinder uses a G1/2 port. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, and a theoretical maximum of 1251 kgf at 1.0 MPa.
The 1000 mm nominal stroke is the maximum length. The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable extend range of 970 to 1000 mm. The retract end is fixed. This mechanism only sets the end position; it does not lock the load, so you need an external rod lock or pilot-operated check valve to hold a load on air loss.
