Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-30
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 300mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

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. It delivers 402 N of push force at 0.5 MPa and 724 N at 0.9 MPa.
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.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-30 Is Used
End-Position Tuning
Dial in the exact retract distance within the 270-300 mm window during commissioning without changing hardware.
Product Changeover
Quickly adjust the stroke stop on packaging lines when switching to a different product size or format.
Variable End Stops
Set precise mechanical limits for light assembly operations needing 402 N of push force at 0.5 MPa.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-30 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa. 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.

- ✓ 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 0.5 MPa it provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
