Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-10
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-10 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 100mm 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 SGCJ125X100-10
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles serious work. It provides a safe working load of about 3682 N, which means you can vertically lift roughly 313 kg with a 2:1 safety margin. The G1/2 port and four steel tie rods clamping the aluminum barrel ensure rigid, reliable operation.
The external adjuster lets you shorten the extend stroke on-site by up to 10 mm, giving a usable range of 90 to 100 mm without changing the cylinder itself. This on-site end-position tuning is paired with a two-way piston seal and adjustable air cushions at both ends. Note that this specific SKU lacks a magnet, so it cannot take a magnetic sensor; you would need the -S variant for CMSG/DMSG/EMSG switches.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-10 Is Used
Press Fit Tuning
Fine-tune the 10 mm extend window on-site to set the exact bottoming position for pressing bearings without swapping the physical cylinder.
Transfer Diverter
Adjust the extend stop to perfectly align a diverter gate profile for varying product sizes on a heavy-duty packaging line.
Pallet Stopper
Use the 6136 N push force to halt heavy pallets, tweaking the 10 mm stroke window to accommodate different pallet thicknesses.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-10 the Right Cylinder?
When sizing this 125 mm bore against its neighbors, it sits at the lower edge of the large-bore family, offering 6136 N push at 0.5 MPa compared to the 10053 N available from the 160 mm bore. The adjustable stroke feature is particularly useful when you want a shared spare across slight stroke variants or need fine end-position tuning on the machine. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this unit has no -S suffix, it cannot accept position sensors. For any stroke over 500 mm, always 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 SGCJ125X100-10 FAQ
This 125 mm bore cylinder features a G1/2 port and delivers 6136 N push / 5734 N pull at 0.5 MPa, 8590 N push / 8028 N pull at 0.7 MPa, and a theoretical maximum of 1251 kgf at 1.0 MPa.
The nominal 100 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable extend range of 90 to 100 mm. The retract end remains fixed.
