Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-40S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-40S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 150mm 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 SGCJ125X150-40S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses four steel rods to clamp its aluminium barrel for high structural rigidity. The built-in magnet supports CMSG, DMSG and EMSG sensors for exact position detection. A G1/2 port supplies the 32 mm rod, yielding a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 margin.
The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 110 to 150 mm without changing the cylinder itself. This on-site end-position tuning is ideal for sharing spares across stroke variants. The retract end remains fixed, and the 40 mm adjustable air cushions purely decelerate the piston near the ends rather than holding the load.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-40S Is Used
Press Fit Tuning
Fine-tune the pressing depth of bearings on-site using the 40 mm extend shortening window, avoiding cylinder removal while dialing in the perfect insertion force.
Divertor Stroke Adjust
Adjust the extend reach of a sorting diverter arm from 150 mm down to 110 mm to handle varying package sizes on the fly without changing the pneumatic setup.
Pallet Stop Positioning
Set precise pallet stop locations on a handling line by trimming the extend stroke, using the CMSG sensor feedback to confirm the exact end position.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-40S the Right Cylinder?
This 125 mm bore sits at the lower edge of the SGCJ range, offering 6136 N push at 0.5 MPa. If your application requires less force, step down to a smaller bore; if you need substantially more thrust, the 160 mm bore provides 10053 N at the same pressure. The -40 mm adjustable window is highly useful when you need to fine-tune the extend end position on-site or want a single spare to cover several stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. The -S suffix means a piston magnet is already fitted for CMSG, DMSG or EMSG switches. Even at 150 mm stroke, always guide the load to prevent side-load wear on the rod seals.
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 SGCJ125X150-40S 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. The air port size is G1/2.
The nominal stroke is 150 mm, which is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 110 to 150 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
