About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X750-10
The AirTAC SAIJ125X750-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. This built-in adjustability allows you to fine-tune the retract end position at commissioning without swapping out the entire cylinder.
It features a 32 mm carbon steel rod and a PT G1/2 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. This model uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

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 SAIJ125X750-10 Is Used
Variable End-Stop Tuning
Dial in the exact 740 to 750 mm retract position during machine commissioning to perfect product ejection without machining custom spacers.
Product Changeover
Quickly adapt the stroke end-position on a packaging line when introducing a new carton size, using the rear screw to trim up to 10 mm of travel.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X750-10 the Right Cylinder?
The 10 mm rear adjuster is ideal for variable end-stops during machine setup or product changeover, replacing the need for fixed external stops. Because the rear adjuster acts only as a travel stop and does not hold the load without live air, use a SAIL or BSAI cylinder if load-holding is required.
With a 750 mm stroke, the unsupported rod is susceptible to side-loading; an external guide bearing is recommended to prevent premature seal wear. For a direct replacement, match the 125 mm bore, 750 mm stroke, 10 mm adjustment, PT G1/2 port, and the required mounting interface.
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 SAIJ125X750-10 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm. This creates a 740 to 750 mm usable travel window, allowing precise end-position tuning without changing the cylinder.
