Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-10S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-10S 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 SGCJ125X350-10S
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 340-350 mm extend stroke window. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity. The G1/2 port feeds the double-acting single rod, and the built-in magnet (-S) supports CMSG, DMSG, or EMSG position switches.
An external adjuster allows you to shorten the extend stroke on-site by up to 10 mm without changing the cylinder mount, while the retract end remains fixed. This on-site end-position tuning is ideal for sharing spares across stroke variants. The standard TPU seal handles -20 to +70 C, with a Viton H option for 0-150 C heat. It handles a safe working load of about 3682 N, lifting roughly 313 kg vertically with a 2:1 margin.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-10S Is Used
Press Fit Tuning
Fine-tune the 10 mm extend window on-site to dial in the exact pressing depth of bearings without swapping the cylinder.
Divertor Stroke Trim
Adjust the extend end position to match varying package widths on a sorting line, ensuring precise diverting contact.
Pallet Stop Calibration
Shorten the extend stroke by up to 10 mm to calibrate the stopping face for mixed pallet sizes while using the G1/2 port.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X350-10S the Right Cylinder?
When sizing this 125 mm bore unit against its neighbours, note it sits at the low edge of the large-bore family. Stepping up to the 160 mm bore increases push force at 0.5 MPa to 10053 N, whereas dropping below 125 mm leaves the ISO 15552 large-bore range. The adjustable stroke helps when you need fine end-position tuning on-site or want a shared spare across slightly different stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S magnet enables CMSG/DMSG/EMSG sensors. For this 350 mm stroke, guide the load externally 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 SGCJ125X350-10S 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. It uses a G1/2 port and a 40 mm adjustable air cushion at each end.
The 10 mm window means an external stop screw lets you shorten the extend stroke on-site from the 350 mm maximum down to 340 mm. The retract end is fixed. This stop sets the end position and is not a load lock; use an external rod lock or pilot-operated check valve to hold a load.
