Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X125-40S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X125-40S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø160mm bore and 125mm stroke, G3/4 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 SGCJ160X125-40S
Delivering 10053 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates a magnetic piston for position sensing. Four steel tie rods clamp the aluminum barrel to the covers, providing rigid alignment while maintaining dimensional interchangeability per the ISO 15552 mounting interface for existing large-bore fixtures. The G3/4 port matches the 160 mm bore standard.
The external -40 mm adjuster lets you shorten the extend stroke on-site from the 125 mm maximum down to 85 mm without changing the cylinder. This on-site end-position tuning is ideal for sharing spares across stroke variants. It handles about 6032 N of safe working load, roughly 512 kg lifted vertically with a 2:1 margin. The default TPU seal offers long life, while a Viton H option extends the temperature range to 0-150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X125-40S Is Used
Press Tonnage Calibration
Fine-tune the 85-125 mm extend stroke on-site to set exact material contact depth without swapping cylinders.
Diverting Arm Stops
Adjust the external stop screw to modify the extend reach on the fly for varying package widths on the line.
Pallet Positioning Pins
Dial in the precise pin engagement depth on-site using the 40 mm window to accommodate different pallet heights.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X125-40S the Right Cylinder?
Size both ways against the 160 mm bore: the 125 mm option yields 6136 N push at 0.5 MPa, while the 250 mm bore provides 24543 N. This model fits neatly in the middle, offering 14074 N at 0.7 MPa. The adjustable stroke helps when you need on-site end-position tuning or want a shared spare across stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix means a built-in magnet for CMSG/DMSG/EMSG switches. For any stroke over 500 mm, use a 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 SGCJ160X125-40S FAQ
This 160 mm bore cylinder features a G3/4 air port. It delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push and 13194 N pull at 0.7 MPa, with a theoretical max of 2050 kgf at 1.0 MPa.
The nominal 125 mm stroke is the maximum. An external adjuster lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable extend range of 85-125 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock.
