Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X250-10
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X250-10 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 250mm 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 SGCJ125X250-10
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 G1/2 port feeds a 32 mm piston rod, and a two-way piston seal ensures reliable double-acting single-rod operation. It handles a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 safety margin.
The -10 code defines a 10 mm external adjuster window, letting you shorten the extend stroke on-site from the 250 mm maximum down to 240 mm without changing the cylinder itself. This fine-tunes the end position perfectly, while the retract end remains fixed. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops cleanly into existing large-bore fixtures. Note this non-magnet SKU cannot take a sensor; adding the -S variant enables CMSG/DMSG/EMSG switches.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X250-10 Is Used
Press Fit Tuning
Fine-tune the exact insertion depth of a bearing press on-site using the 10 mm extend window without swapping the actuator.
Divertor Gate Stop
Adjust the extend end-position by a few millimetres to perfectly match new package sizes on a sorting line.
Pallet Positioning
Set the precise push-off distance for pallet handling, accommodating minor frame tolerances directly at the machine.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X250-10 the Right Cylinder?
This 125 mm bore generates 6136 N push at 0.5 MPa, sitting at the low edge of the SGCJ range. If you need less force, the smaller bores scale down accordingly, while stepping up to the 160 mm bore yields 10053 N for heavier demands. The 10 mm adjustable window is ideal when you need to share one spare cylinder across slightly different stroke variants or fine-tune the end position on-site. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a non-S SKU, it cannot accept magnetic sensors. For any stroke over 500 mm, always use a guide rail to prevent rod side-loading and premature seal wear.
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 SGCJ125X250-10 FAQ
At 0.5 MPa it delivers 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical maximum is 1251 kgf at 1.0 MPa. This 125 mm bore cylinder uses a G1/2 air port and a 32 mm rod with an M27x2.0 thread.
The nominal 250 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 10 mm on-site, giving a usable extend range of 240 to 250 mm. The retract end is fixed. This mechanism only sets the end position; it does not lock the load.
