About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-100
The AirTAC SAIJ32X115-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 115 mm travel but incorporates a 100 mm adjustment range, allowing you to fine-tune the effective extension anywhere between 15 mm and 115 mm during commissioning. This compact bore delivers 402N of push force at 0.5 MPa and operates efficiently between 30-800 mm/s.
Built with a SUS304 stainless steel rod for corrosion resistance, this variant uses PT tapered port threads (G1/8) and lacks a magnet. The rear stopper lets you dial in the exact end-position without swapping hardware, while the extruded aluminum barrel integrates dual sensor grooves. Remember, the adjuster acts as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-100 Is Used
Variable End-Stop Calibration
Dial in the exact 15-115 mm extension during machine setup to test multiple product sizes without disassembling the pneumatic rig.
Product Changeover
Quickly shorten the cylinder stroke on packaging lines when switching to different package lengths, saving valuable retooling time.
Prototype Positioning
Use the 100 mm adjustment range to find the optimal clamping distance on test fixtures before locking down the final dimensions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-100 the Right Cylinder?
Choose this 32 mm bore when your application requires precise end-position tuning across a 15-115 mm window, avoiding the need to stock multiple fixed-stroke SAI cylinders. If your project demands higher thrust, stepping up to the 40 mm bore yields 628N of push force at 0.5 MPa. Because the stroke is 115 mm, side-loading is minimal, but always ensure the M10x1.25 rod thread is properly aligned to prevent binding.
For an exact ISO 15552 replacement match, specify the SAIJ32X115-100 with a 32 mm bore, 115 mm stroke, 100 mm adjustment, PT G1/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet. Since the rear screw only decelerates the travel end, use an external rod lock or a SAIL cylinder if you need fail-safe load holding without live air.
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 SAIJ32BX115-100 FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective travel from the nominal 115 mm down to 15 mm. This provides a 100 mm tuning window for precise end-positioning without replacing the cylinder.
At 0.5 MPa operating pressure, the SAIJ32X115-100 provides 402N of push force and 345N of pull force. It can reach up to 724N of push force at 0.9 MPa.
