About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-50
The AirTAC SAIJ32X130-50 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. By dialing the external stopper, you can trim the nominal 130 mm travel back by up to 50 mm, yielding a usable 80-130 mm end-position window. This allows precise end-tuning at commissioning without swapping the unit or adding external stops. Delivering 402 N of push force and 345 N of pull force at 0.5 MPa, it fits compact automation tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds between 30 and 800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It uses a PT tapered G1/8 port and a 27 mm air cushion at both ends to decelerate the load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-50 Is Used
Product Changeovers
Dial in the exact 80 to 130 mm travel window during format changes without replacing the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the retract stop during commissioning to absorb mechanical tolerances and achieve precise final positioning.
Corrosive Environments
Leverage the SUS304 stainless steel rod for reliable actuation in packaging lines or environments requiring high corrosion resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-50 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa, but step up to a 40 mm bore (628 N push) if your payload exceeds the 345 N pull capacity. An adjustable stroke is ideal for machine changeovers where the exact end position varies by product size, unlike a fixed-stroke SAI cylinder. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for fail-safe load holding, select an SAIL or BSAI cylinder. To match this ISO 15552 footprint, specify the 32 mm bore, 130 mm stroke, 50 mm adjustment, PT port, SUS304 rod, and no 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 SAIJ32BX130-50 FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop that shortens the effective stroke. For this 130 mm nominal stroke model, you can trim the travel back by up to 50 mm, creating an 80 to 130 mm usable window. The adjuster is a stop, not a lock, and requires live air to hold the load.
