About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X110-30
The AirTAC SAIJ125X110-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 80-110 mm usable travel window from its 110 mm nominal stroke. The extruded aluminum barrel includes dual sensor grooves, accommodating CMSE reed and DMSE electronic switches when a magnet is specified.
This model utilizes a robust 32 mm carbon steel rod and a PT tapered G1/2 port to handle high flow requirements. The rear adjustment mechanism allows precise end-position tuning during commissioning without adding external stops. It supports a speed range of 30-500 mm/s and features variable air cushions at both ends to manage kinetic energy.

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 SAIJ125X110-30 Is Used
Product Changeover Tuning
Dial in the exact end position within the 80-110 mm window during machine setup for varying product sizes without changing the cylinder.
Commissioning Calibration
Fine-tune the retract end position during initial commissioning to perfect timing without adding bulky external mechanical stops.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X110-30 the Right Cylinder?
Choose this 125 mm bore when an 80 mm bore falls short—yielding 2513 N versus this model's 6136 N at 0.5 MPa. The 30 mm adjustment range is ideal for product changeovers where exact end-of-stroke positioning must be dialed in on the fly, avoiding the need to swap out a fixed-stroke SAI cylinder. Mounting options include the SAIJ subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.
For any application exceeding 300 mm of stroke, external guide rails are recommended to manage side loads, though this 110 mm unit is compact. Remember that the rear adjuster acts solely as a travel stop and does not hold the load without live air pressure; for true pneumatic locking, consider the SAIL or BSAI series instead.
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 SAIJ125X110-30 FAQ
At 0.7 MPa, the push force increases to 8590 N.
The rear adjuster allows you to shorten the effective stroke by up to 30 mm, providing a usable travel window of 80 to 110 mm from the nominal 110 mm stroke. This stopper only sets the end position and does not lock the load without air pressure.
