About the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-75
Generating 6136 N of push force at 0.5 MPa, this ISO 15552 tie-rod cylinder brings four steel rods and an aluminum barrel to heavy-duty actuation. The G1/2 port feeds a 32 mm rod, yielding a safe working load of roughly 3682 N or about 313 kg lifted vertically with a 2:1 margin.
The external adjuster shortens the extend stroke on-site by up to 75 mm, giving a usable range of 925 to 1000 mm without changing the cylinder. The retract end remains fixed. A two-way piston seal and adjustable 40 mm air cushions manage deceleration, while the Viton H option extends service to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-75 Is Used
Transfer Line Diverter
Fine-tune the 925 to 1000 mm extend reach on-site to push heavy pallets onto a bypass lane without swapping the actuator.
Stacker Height Calibration
Dial in the exact upper stop position for tier stacking, using the 75 mm external window to adapt to varying pallet heights.
Press End-Position Trim
Adjust the extend end point on the shop floor to set precise forming depth, avoiding mechanical hard-stops on the machinery.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-75 the Right Cylinder?
Size this 125 mm bore against the 160 mm option if you need up to 10053 N at 0.5 MPa, or drop to smaller bores for lighter loads. The 75 mm adjust window lets you fine-tune the extend end position on-site, ideal for sharing one spare across multiple stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2. Because this is a non-magnet SKU, it cannot take CMSG or DMSG sensors. For the 1000 mm stroke, use an external guide to prevent rod bending and side-load damage.
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 SGCJ125X1000-75 FAQ
It delivers 6136 N push and 5734 N pull at 0.5 MPa, or 8590 N push and 8028 N pull at 0.7 MPa. The theoretical max is 1251 kgf at 1.0 MPa. The air port is G1/2.
An external stop screw shortens the extend stroke by up to 75 mm on-site, giving a usable extend range of 925 to 1000 mm. The nominal 1000 mm is the maximum, and the retract end is fixed. This stop only sets position and does not lock the load.
