About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-30S
The AirTAC SAIJ32X115-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the travel, creating an 85-115 mm usable window from its 115 mm nominal stroke. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance. The -S magnet enables precise end-position detection using AirTAC CMSE reed or DMSE electronic solid-state switches.
This model features a PT tapered G1/8 port and a 12 mm rod with an M10x1.25 thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-30S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 85-115 mm window during machine commissioning without physically replacing the cylinder or adding external stopper blocks.
Product Size Changeover
Quickly adapt the stroke length on packaging lines handling varying product sizes, using the rear screw to accommodate different dimensions on the fly.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for precise positioning tasks in food, medical, or chemical processing where moisture and corrosion are present.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-30S the Right Cylinder?
Choose this 32 mm bore when an application requires precise variable end-stops rather than a fixed-stroke SAI cylinder, such as during machine setup or product-size changeovers. If your process needs greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the 115 mm stroke is under 300 mm, side-load risks are minimal, though the 12 mm rod thread still handles moderate lateral loads.
To match this ISO 15552 interchangeable cylinder, specify a 32 mm bore, 115 mm stroke, 30 mm adjustment, PT G1/8 port, and the -S magnet. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ does not hold loads without live air, so for fail-safe load holding, consider an external rod lock or the SAIL series.
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 SAIJ32BX115-30S FAQ
The rear adjusting screw acts as a mechanical stop that shortens the effective stroke by up to 30 mm. This gives the 115 mm nominal stroke a usable travel window of 85 to 115 mm, allowing fine-tuning of the end position without changing the cylinder.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
