About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-30
The AirTAC SAIJ32X300-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end-position. With a 300 mm nominal stroke and a 30 mm adjustment range, it provides a usable travel window of 270 to 300 mm. This eliminates the need to swap cylinders or add external stops during product changeovers.
This unit features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and uses PT tapered port threads (G1/8). The extruded aluminum barrel includes sensor grooves on both sides. If position monitoring is required later, you can add AirTAC CMSE reed or DMSE solid-state sensors, though this specific SKU ships without a magnet. The rear screw acts purely as a mechanical stop to set deceleration and travel; it does not hold the load without live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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.

Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-30 the Right Cylinder?
If you need less force, a 25 mm bore might suffice, but stepping up to a 40 mm bore increases the push force to 628 N for heavier payloads. The adjustable stroke is ideal for machine setups requiring variable end-stops, whereas a fixed-stroke SAI cylinder is better for dedicated, single-task stations. For true load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as this adjuster is only a stop.
Because the 300 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 thread face higher side-load risks. An external guide is recommended to prevent rod deflection. This cylinder is dimensionally interchangeable per ISO 15552 mounting interfaces and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 Adjustable Cylinder SAIJ32 SAIJ32AX300-30 FAQ
The rear adjuster screw lets you shorten the effective travel by up to 30 mm, giving a usable stroke window of 270 to 300 mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air.
At 0.9 MPa, the push force increases to 724 N.
