Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-40S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-40S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1000mm 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 SGCJ125X1000-40S
Generating 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates a 1000 mm stroke with a 40 mm external adjuster. Four steel tie rods clamp the aluminium barrel to the covers, and the G1/2 port matches the 125 mm bore standard. The built-in piston magnet supports CMSG, DMSG and EMSG switches for precise position detection.
The on-site adjuster shortens the extend stroke down to 960 mm without changing the mount, while the retract end remains fixed. It 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 operate from -20 to +70 C, with a Viton H option extending heat resistance up to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-40S Is Used
Transfer Line Diverter
Fine-tune the 1000 mm extend position by up to 40 mm on-site to align with varying pallet sizes without remounting the cylinder.
Vertical Lift Gate
Lifts roughly 313 kg of gate load with a 2:1 safety margin, using the G1/2 port and adjustable cushions to control the descent.
Heavy Press Ejector
Uses the 6136 N push force at 0.5 MPa to eject parts, relying on the tie-rod rigidity to maintain alignment under sudden impact.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-40S the Right Cylinder?
When sizing this 125 mm bore unit against its neighbours, stepping down is not an option as it is the smallest in the SGCJ family, but stepping up to the 160 mm bore raises the 0.5 MPa push force to 10053 N. The 40 mm adjustable window is ideal for sharing one 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 -S suffix means a magnet is already fitted for sensors. Because the stroke is 1000 mm, external rod-end guidance is mandatory to prevent rod bending under side 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 SGCJ125X1000-40S FAQ
This 125 mm bore cylinder has a G1/2 port. It delivers 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 force of 1251 kgf at 1.0 MPa.
The nominal 1000 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 40 mm on-site, giving a usable extend range of 960 to 1000 mm. The retract end is fixed, and this mechanism only sets the end position, it does not lock the load.
