Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-75
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-75 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 SGCJ125X100-75
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 aluminium barrel for high structural rigidity. The G1/2 port feeds a 32 mm rod, and a two-way piston seal ensures reliable pressure containment across the 125 mm bore.
An external adjuster allows you to shorten the extend stroke on-site by up to 75 mm, meaning the usable forward travel spans 25 to 100 mm while the retract position stays fixed. This on-site tuning is ideal for dialling in exact end positions without swapping hardware. The default TPU seals handle -20 to +70 C, while a Viton H option extends heat resistance to 150 C. Handling a safe working load of roughly 3682 N, it can lift about 313 kg vertically with a 2:1 margin.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-75 Is Used
Press Stroke Tuning
Dial in the exact 25 to 100 mm forming depth on-site using the external adjuster without disassembling the press tooling.
Divertor Gate Positioning
Fine-tune the extend stop to perfectly match new package sizes on a sorting line, relying on the 6136 N thrust to swing heavy gates.
Pallet Stop Alignment
Adjust the end position in the field to handle varying pallet heights, using the fixed retract end to maintain a consistent home location.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-75 the Right Cylinder?
When sizing this unit, the smaller 160 mm bore raises the 0.5 MPa push force to 10053 N, whereas stepping down drops you out of the large-bore ISO 15552 family. The -75 mm adjust window is highly useful when you need to share one spare cylinder across several stroke variants or fine-tune the end position during machine commissioning. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. Because this specific SKU lacks the -S suffix, it cannot accept a magnetic sensor; you would need the -S variant to use CMSG, DMSG or EMSG switches. For any application approaching or exceeding 500 mm of travel, always guide the load externally to prevent side-load damage to 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 SGCJ125X100-75 FAQ
This 125 mm bore cylinder features a G1/2 air port and a 32 mm rod. It generates 6136 N push and 5734 N pull at 0.5 MPa, increasing to 8590 N push and 8028 N pull at 0.7 MPa. The theoretical maximum force is 1251 kgf at 1.0 MPa.
The nominal stroke is 100 mm, which is the maximum forward travel. An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable extend range of 25 to 100 mm. The retract end is fixed, and this mechanism only sets the end position; it does not lock or hold the load.
