About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X700-10
The AirTAC SAIJ125X700-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 700 mm stroke that can be fine-tuned down by up to 10 mm, giving an effective usable travel window of 690 to 700 mm.
This model features a carbon steel piston rod with an M27x2 thread and a PT G1/2 port. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. The rear adjuster functions purely as a mechanical stop to dial in the end position during commissioning; it does not lock or hold the load without live air pressure.

Theoretical Output Force (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 5734 N | 5734 N |
| 0.7 MPa | 8027 N | — |
| Max (@1.0 MPa) | 1169 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125X700-10 Is Used
Heavy Press Tolerance Tuning
Dial in the exact 690-700 mm end-stop during press assembly to compensate for mechanical wear or material thickness variations without external stopper blocks.
Product Size Changeover
Quickly adjust the retract position on a packaging line when switching between product sizes, using the 10 mm rear screw for precise end-point calibration.
Large Conveyor Positioning
Fine-tune the stroke end on heavy-duty conveyor diverters or large format material handling equipment where exact retraction is critical for timing.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X700-10 the Right Cylinder?
The 10 mm adjustment range is ideal for fine-tuning the retract end during machine setup or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead. Because the stroke is 700 mm, an external guide is recommended to prevent side-loading on the unsupported rod. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable with ISO 15552 cylinders.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ125 Adjustable Cylinder SAIJ125X700-10 FAQ
It can reach a maximum of 1251 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 700 mm down to 690 mm. It is used for fine-tuning end positions at commissioning and is not a lock, meaning the cylinder requires live air to hold its load.
