Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X130-40S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X130-40S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 130mm 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 SGCJ125X130-40S
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 piston magnet supports CMSG, DMSG and EMSG switches for precise position detection, while the G1/2 port handles the required air volume.
An external adjuster lets you shorten the extend stroke on-site by up to 40 mm, meaning the usable forward travel spans 90 to 130 mm without changing the cylinder itself. This on-site end-position tuning is ideal for shared spares across stroke variants. The unit handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin. Standard TPU seals offer long life, though a Viton H option extends the operating range up to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X130-40S Is Used
Press Tonnage Calibration
Use the 40 mm extend-shortening window to dial in the exact 90 to 130 mm contact point on a light stamping press without shimming the tooling.
Divert Arm Positioning
Adjust the extend stop on-site to match varying package sizes on a sorting line, ensuring the divert arm hits the precise push location every time.
Pallet Stopper Gate
Leverage the 6136 N push force and magnetic sensors to act as a heavy pallet stop, fine-tuning the gate extension to accommodate different pallet depths.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X130-40S the Right Cylinder?
When sizing this 125 mm bore, stepping down is not an option as it is the smallest in the SGCJ range, but stepping up to the 160 mm bore increases push force at 0.5 MPa to 10053 N. The 40 mm adjustable window is particularly useful when you need to fine-tune the extend end position after installation or share a single spare across multiple stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. Because this is an -S model, it arrives magnet-ready for CMSG, DMSG or EMSG sensors. For any stroke length at or above 500 mm, always use a guide rail to prevent side-load damage to 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 SGCJ125X130-40S FAQ
This 125 mm bore cylinder features a G1/2 port and delivers 6136 N push and 5734 N pull at 0.5 MPa. At 0.7 MPa, push increases to 8590 N and pull to 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
The nominal 130 mm stroke is the maximum forward travel. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 90 to 130 mm. The retract end remains fixed, and this stop only sets the end position—it does not lock the load.
