About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-30
The AirTAC SAIJ32X105-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. With a 105 mm nominal stroke and a 30 mm adjustment range, it provides a usable travel window of 75 to 105 mm. This flexibility is ideal for machine setup and product changeovers, eliminating the need to swap the entire cylinder or bolt on external stops.
In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides, and the standard carbon steel rod has an M10x1.25 thread. The rear adjuster acts purely as a mechanical stop for position tuning and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-30 Is Used
Machine Changeover
Dial in the 75-105 mm travel window during product size changes without physically replacing the cylinder or adding external stops.
End-Position Tuning
Use the rear adjuster to precisely set the retract distance for delicate picking or pressing operations at commissioning.
Variable End Stops
Ideal for diverter arms or gating mechanisms where the exact stopping point needs occasional field adjustment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-30 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa. If your setup demands less force, stepping down is not an option in the ISO 15552 range, but stepping up to a 40 mm bore yields 628 N. The adjustable stroke is selected over a fixed SAI model when you need variable end-stops during commissioning. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 105 mm stroke, 30 mm adjustment, PT tapered port thread, and standard carbon steel rod. Because this is a non-magnetic variant, position sensing via CMSE or DMSE switches is not supported without the -S option. The approved mounting set includes 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 SAIJ32X105-30 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it achieves 82 kgf.
The rear adjuster allows you to shorten the 105 mm nominal stroke by up to 30 mm, creating a usable travel window of 75 to 105 mm. The adjuster functions as a mechanical stop and does not lock the load without live air.
