Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-30
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-30 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 SGCJ125X100-30
Delivering 6136 N of push force at 0.5 MPa, this ISO 15552 tie-rod cylinder features an external adjuster that shortens the extend stroke on-site by up to 30 mm. The nominal 100 mm stroke serves as the maximum, yielding a usable 70 to 100 mm extend range while the retract end remains fixed. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the G1/2 port handles the 125 mm bore airflow.
This genuine ISO 15552 mounting interface drops directly into existing large-bore fixtures without compatibility issues. It handles about 3682 N of safe working load, which translates to roughly 313 kg lifted vertically with a 2:1 margin. The standard TPU seals offer long service life, though a Viton H option extends the operating temperature range up to 150 C. Note that this specific SKU lacks a magnet and cannot accept CMSG or DMSG sensors.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-30 Is Used
Press Fit Tuning
Adjusts the 100 mm extend stroke down by 30 mm to set precise contact pressure on bearing inserts without machining new stops.
Transfer Diverter
Fine-tunes the extend end position on-site to perfectly align a divert gate with varying product widths on the line.
Pallet Stopper
Shortens the extend stroke by up to 30 mm to accommodate different pallet depths while maintaining a fixed retract position.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-30 the Right Cylinder?
Size this 125 mm bore against the neighboring 160 mm option, which jumps to 10053 N of push force at 0.5 MPa, or step down if lower forces are adequate. The 30 mm adjustable window is ideal when you need to fine-tune the extend end position across multiple shared spares without swapping the entire cylinder. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this SKU has no -S suffix, it cannot support magnetic sensing; choose the -S variant for CMSG or DMSG switches. Even at 100 mm, always guide the rod to prevent side-loading 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 SGCJ125X100-30 FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull force. At 0.7 MPa it delivers 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. This 125 mm bore cylinder uses a G1/2 air port and features a 40 mm adjustable air cushion at both ends.
The external adjuster allows you to shorten the extend stroke on-site by up to 30 mm. The nominal 100 mm stroke is the maximum, so the usable extend range is 70 to 100 mm. The retract end remains fixed. This mechanism only sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve for load holding.
