Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-75S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-75S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 160mm 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 SGCJ125X160-75S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder features a 125 mm bore and a built-in magnet for position sensing. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the G1/2 port handles the required airflow. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without custom brackets.
The external adjuster lets you shorten the extend stroke on-site by up to 75 mm, giving a usable forward range of 85 to 160 mm while the retract end remains fixed. This means you can fine-tune the end position without physically swapping the cylinder, making a single spare part viable across multiple stroke variants. It handles about 3682 N of real work safely, which translates to lifting roughly 313 kg vertically with a 2:1 margin. The standard TPU seals offer long life, though a Viton H option extends operation to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-75S Is Used
Press Fit Tuning
Fine-tune the 85 to 160 mm extend stroke on-site to dial in the exact insertion depth for bearing press fits without changing the cylinder.
Variable Stop Positioning
Shorten the extend stroke by up to 75 mm to accommodate different product lengths on a packaging line using a single actuator.
Pallet Lift Dwell
Leverage the 313 kg vertical lift capacity to raise pallets, adjusting the forward stop externally to set precise dwell heights.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-75S the Right Cylinder?
Size this 125 mm bore against its neighbors: a 160 mm bore provides 10053 N at 0.5 MPa for heavier loads, while dropping below 125 mm loses the large-bore advantage. The adjustable stroke shines when you need on-site end-position tuning or want to standardize spares across slightly different stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix means a piston magnet is present for CMSG, DMSG, or EMSG sensors. For any stroke over 500 mm, use a guide rail to prevent 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 SGCJ125X160-75S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 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 port.
The nominal 160 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, yielding a usable forward range of 85 to 160 mm. The retract end is fixed, and this stop only sets the end position; it does not lock the load.
