Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-10S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-10S 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 SGCJ125X100-10S
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 aluminum barrel for high structural rigidity. A built-in piston magnet supports CMSG, DMSG and EMSG switches for precise position detection, while the G1/2 port handles the 30-500 mm/s speed range.
The external adjuster allows you to shorten the extend stroke on-site by up to 10 mm, giving a usable range of 90-100 mm without changing the cylinder itself. This on-site fine-tuning is ideal for shared spares across stroke variants. It handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-10S Is Used
Press Fit Tuning
Use the 10 mm extend-shortening window to dial in the exact bottoming position of a press fit without remachining stops.
Divertor Gate Adjustment
Fine-tune the actuation reach on a conveyor sorting gate on-site to accommodate different package widths.
Shared Spare Actuator
Stock one cylinder and adjust the extend stroke down 10 mm to cover multiple 90-100 mm positioning tasks.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-10S the Right Cylinder?
When sizing this 125 mm bore unit, stepping down is not an option as it is the low edge of the SGCJ range, producing 6136 N push at 0.5 MPa. Stepping up to the 160 mm bore yields 10053 N push if your application outgrows this capacity. The adjustable stroke helps when you need to tune the end position on-site or want a shared spare across slightly different stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2. The included -S magnet enables CMSG/DMSG/EMSG sensor use. Since the stroke is only 100 mm, side-load guide requirements are minimal compared to long-stroke installations.
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 SGCJ125X100-10S 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 air port size is G1/2.
The nominal 100 mm stroke is the maximum. The external stop screw lets you shorten the extend stroke on-site by up to 10 mm, yielding a usable extend range of 90-100 mm. The retract end is fixed. This mechanism only sets the end position; it does not lock the load.
