Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-30S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-30S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 200mm 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 SGCJ125X200-30S
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 piston magnet for position sensing. Four steel tie rods clamp the aluminum barrel to the covers, providing structural rigidity while remaining dimensionally interchangeable per the ISO 15552 mounting interface. It connects via a G1/2 port and moves the 32 mm rod at 30-500 mm/s.
The -30 code defines an external adjuster window that lets you shorten the extend stroke on site by up to 30 mm, yielding a usable forward travel of 170-200 mm without changing the cylinder itself. This on-site end-position tuning is ideal for sharing spares across stroke variants. It handles about 3682 N of safe working load, which means you can vertically lift roughly 313 kg with a 2:1 margin. The standard TPU seals offer long life, though a Viton H option extends the operating temperature range up to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-30S Is Used
Press Fit Tuning
Micro-adjust the 30 mm extend window on-site to set precise bottoming force for bearing insertion without swapping cylinders.
Divertor Stroke Trim
Fine-tune the actuator end position to match varying package sizes on a sorting line, using the magnet for exact timing.
Pallet Stop Calibration
Dial in the exact 170-200 mm extend position to halt pallets securely while relying on the 6136 N thrust to absorb impact.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X200-30S the Right Cylinder?
Size this 125 mm bore against its neighbors: a 160 mm bore provides 10053 N of push at 0.5 MPa if you need more power, while smaller alternatives offer less. The adjustable stroke mechanism is a major selection driver here, allowing precise on-site end-position tuning and letting one spare cover multiple stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this SKU includes the -S magnet, it directly accepts CMSG, DMSG, or EMSG sensors for switching. At a 200 mm stroke, side loads are minimal, but always guide the rod end to prevent binding. Note that a plain cylinder does not hold load on air loss; use an external rod lock or pilot-operated check valve for suspended loads.
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 SGCJ125X200-30S FAQ
This 125 mm bore cylinder uses a G1/2 port. It generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum of 1251 kgf at 1.0 MPa.
The external adjuster lets you shorten the extend stroke by up to 30 mm on site, giving a usable forward travel of 170-200 mm. The nominal 200 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position but does not lock the load.
