About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-75
The AirTAC SAIJ32X190-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 402N of push force at 0.5 MPa. Its defining feature is the 75mm adjustment range, which creates a highly flexible usable travel window between 115 and 190mm. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
Built with an SUS304 stainless steel rod and PT tapered ports, this 32mm bore unit runs at speeds of 30-800mm/s. The rear screw acts purely as a travel stop to decelerate the load alongside the standard air cushions; it is not a locking device. For applications requiring position holding without live air pressure, an external rod lock or related SAIL cylinder is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-75 Is Used
Product Changeovers
Dial in the exact retract distance from 115 to 190mm during product size transitions without changing cylinder hardware.
Machine Setup
Fine-tune the end-of-stroke position during initial commissioning to perfect the mechanical timing of your assembly process.
Variable End Stops
Adjust the stopping point on the fly for conveyor sorting arms that handle multiple package sizes on a single line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-75 the Right Cylinder?
Choose this 32mm bore when your application requires up to 402N push force at 0.5 MPa but demands a variable end-stop for frequent product-size line changeovers. If your setup requires less force, stepping down is not an option in this series, but stepping up to a 40mm bore yields 628N if you need higher margin. The generous 75mm adjuster on this 190mm stroke lets you fine-tune the retract distance on the fly, a major advantage over a fixed-stroke SAI cylinder.
Because this is a 190mm stroke, the 12mm rod diameter handles moderate side loads, but long unsupported strokes still require an external guide. This model is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2. As a non-magnet variant, it does not support CMSE or DMSE sensors.
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 SAIJ32BX190-75 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw allows you to trim the effective stroke by up to 75mm. This creates a usable travel window from 115mm to 190mm, letting you set the exact retract end-position without adding external stops.
