About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-30S
The AirTAC SAIJ32X90-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 90 mm stroke that can be fine-tuned down by up to 30 mm, creating a precise 60-90 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it fits perfectly into compact setups requiring exact end-position calibration.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE or DMSE sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and fluid control is managed via a PT G1/8 port. The rear stopper screw allows you to dial in the retract position during commissioning without adding external stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-30S Is Used
Changeover Calibration
Dial in the 60-90 mm travel window during machine changeovers to accommodate different product sizes without swapping hardware.
End-Position Trimming
Fine-tune the retract stop during commissioning to perfect alignment and avoid mechanical crashes in tight assembly spaces.
Corrosive Testing Setup
Leverage the SUS304 stainless steel rod in light chemical or washdown environments while adjusting the stroke to test sensor limits.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-30S the Right Cylinder?
Select this 32 mm bore when an application demands 402 N push force at 0.5 MPa but requires variable end-stops for product changeovers; if you need less force, dropping to a smaller bore is advised, while stepping up to a 40 mm bore yields 628 N. Choose the SAIJ adjustable-stroke design over a fixed SAI cylinder when you need to trim the travel window on the fly. Remember that the rear adjuster acts only as a travel stop, not a lock, so the SAIJ32X90-30-S cannot hold a load without live air—use a SAIL or BSAI cylinder for fail-safe load holding. To match this ISO 15552 interchangeable cylinder, confirm the 90 mm stroke, 30 mm adjustment, PT G1/8 port, and the -S magnet.
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 SAIJ32BX90-30S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The 90 mm nominal stroke can be adjusted back by up to 30 mm, resulting in a usable travel window of 60-90 mm.
The rear adjuster is a mechanical stopper that physically limits the retract stroke to fine-tune the end position. It is not a locking device, so the cylinder cannot hold a load without continuous air pressure; for load-holding, consider a SAIL or BSAI cylinder.
