About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-50
The AirTAC SAIJ32X190-50 is a double-acting, adjustable-stroke ISO 15552 profile cylinder featuring a robust 12mm SUS304 stainless steel rod and PT tapered port threads. A rear-mounted stroke adjuster allows you to dial back the 190mm nominal travel by up to 50mm, creating a precise 140-190mm usable window for on-the-fly end-position tuning.
Delivering 402N of push force at 0.5MPa, this compact 32mm bore unit integrates variable air cushions at both ends to soften impact. The adjuster acts purely as a mechanical stop to set the retract distance, meaning it will not hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-50 Is Used
Machine Changeover
Quickly fine-tune the 140-190mm travel window during product size transitions on a packaging line without adding external stops.
End-Position Trimming
Dial in the exact retract distance at commissioning using the rear adjuster, avoiding mechanical dead-ends or cylinder replacement.
Light-Duty Clamping
Provides 402N of push force at 0.5MPa for positioning light workpieces, relying on the SUS304 rod for environmental resilience.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-50 the Right Cylinder?
Choose this SAIJ32X190-50 when your machine setup requires variable end-stops or frequent product changeovers without swapping cylinders. If you need higher force, stepping up to the 40mm bore yields 628N of push force at 0.5MPa. Conversely, if your force requirements drop, the smaller SAI series lacks this built-in adjustment flexibility.
For load-holding applications without live pressure, this cylinder is insufficient as the rear screw is a stop rather than a lock; consider an AirTAC SAIL or BSAI series instead. This model uses PT tapered G1/8 ports, omits the magnet for sensors, and supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) while omitting FB, CA, CB, and CR brackets.
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 SAIJ32BX190-50 FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7MPa, the push force increases to 563N.
The rear adjuster screw acts as a mechanical stop that can shorten the 190mm nominal stroke by up to 50mm, giving an effective travel window of 140-190mm. It requires live air to function and does not lock the load in place.
