Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-30S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-30S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 350mm 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 SGCJ125X350-30S
Delivering 6136 N of push force at 0.5 MPa, this ISO 15552 tie-rod cylinder handles about 3682 N of safe working load, roughly 313 kg lifted vertically with a 2:1 margin. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the G1/2 port matches the 125 mm bore standard.
The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 320-350 mm without changing the cylinder itself. Because the -S suffix denotes a built-in piston magnet, you can fit CMSG, DMSG, or EMSG switches for position sensing. Standard TPU seals offer long life, while a Viton H option raises the operating ceiling to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-30S Is Used
Press Fit Tuning
Dial in the exact 320-350 mm extend position on-site to seat bearings without over-traveling.
Divertor Gate Stop
Adjust the extend stop in the field to alter the gate angle for varying package sizes.
Pallet Lift Limit
Fine-tune the lift height to clear different pallet stacks using the external adjuster.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-30S the Right Cylinder?
When sizing this unit, the neighboring 160 mm bore steps up to 10053 N push at 0.5 MPa, whereas the 125 mm bore sits at the low edge of this large-bore family. The adjustable stroke is ideal for sharing a single spare across multiple stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The included magnet supports CMSG/DMSG/EMSG sensors. For any stroke at or above 500 mm, always use a external guide 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 SGCJ125X350-30S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it yields 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa. The G1/2 port supplies the air.
The nominal 350 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 30 mm on-site, giving a usable range of 320-350 mm. The retract end is fixed. This stop only sets the end position; it is not a load lock.
