About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X230-30
The AirTAC SAIJ125X230-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 200-230 mm, allowing you to dial back the nominal 230 mm stroke by up to 30 mm during commissioning. Belonging to the 125 mm bore class, it delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa, making it suited for heavy-duty positioning tasks.
This model incorporates a 32 mm carbon steel rod with an M27x2 thread, providing a robust interface for high side-load resilience. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125X230-30 Is Used
Machine Changeovers
Fine-tune the 200-230 mm travel window during product format changes without physically replacing the cylinder or adding external stopper blocks.
Variable End-Stop Positioning
Ideal for heavy-duty conveyors where the retraction end-position needs occasional adjustment to accommodate varying package sizes or downstream processes.
Heavy-Duty Clamping
Provides up to 6136 N of clamping force at 0.5 MPa, with the rear stopper allowing precise tuning of the clamping depth to prevent workpiece damage.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X230-30 the Right Cylinder?
Choose this 125 mm bore adjustable-stroke cylinder when your application requires a push force around 6136 N (at 0.5 MPa) and on-the-fly end-stop tuning without swapping cylinders. If your force requirements are lower, stepping down to an 80 mm bore yields 2513 N of push force. The 30 mm adjustment range is ideal for accommodating product size changes on a conveyor line. Because the 230 mm stroke is below the 300 mm threshold, external side-load guides are less critical here than on longer strokes, though the thick 32 mm rod inherently handles deflection well.
As an ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders. To match this exact unit, specify a 125 mm bore, 230 mm stroke, 30 mm adjustment range, PT tapered port (G1/2), and no magnet. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster is a travel stop, not a lock; for load-holding without live air, consider the SAIL or BSAI series.

- ✓ 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 SAIJ125X230-30 FAQ
At 0.5 MPa operating pressure, the SAIJ125X230-30 generates a push (extend) force of 6136 N and a pull (retract) force of 5734 N. At the maximum pressure of 1.0 MPa, it can deliver up to 1251 kgf of push force.
The rear mechanical adjuster allows you to shorten the effective stroke from the nominal 230 mm down to 200 mm. This creates a 200-230 mm usable travel window for fine-tuning the end position at commissioning. The adjuster acts only as a travel stop and does not lock the load without continuous air pressure.
