About the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X400-10S
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 position sensing, while the G1/2 port manages air flow efficiently.
An external adjuster allows you to shorten the extend stroke on-site by up to 10 mm, giving a usable range of 390 to 400 mm without changing the cylinder itself. It handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin. The two-way piston seal and adjustable air cushions ensure reliable deceleration at both ends.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X400-10S Is Used
Press Fit Tuning
Fine-tune the 10 mm extend window on-site to dial in exact pressing depths for bearing insertion without swapping cylinders.
Divertor Adjustment
Shift the extend end position by a few millimetres to accommodate different package sizes on a sorting line.
Pallet Stopper
Use the 6136 N push force to halt heavy pallets, adjusting the stop point precisely to match pallet geometry.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X400-10S the Right Cylinder?
When sizing this unit, stepping down to a smaller bore lowers the force output, while stepping up to a 160 mm bore increases the push force to 10053 N at 0.5 MPa. The 10 mm adjustable window is ideal for fine-tuning end positions on-site or sharing spares across slightly different stroke variants. You can mount it using FA, LB, TC, FTC, TCM1 or TCM2 accessories per the ISO 15552 interface. The included -S magnet enables sensor use, and for any stroke length of 400 mm or more, always use an external guide to prevent side-load 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 SGCJ125X400-10S 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 external adjuster lets you shorten the extend stroke by up to 10 mm on-site, yielding a usable extend range of 390 to 400 mm. The nominal 400 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position and does not lock the load.
