About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-20
The AirTAC SAIJ32X190-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 170 to 190 mm, allowing you to dial back the 190 mm nominal stroke by up to 20 mm during commissioning without adding external stops. The 32 mm bore delivers 402 N of push force at 0.5 MPa, making it suited for lighter-duty handling tasks.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-20 Is Used
Machine Setup Changeover
Fine-tune the retract end position by up to 20 mm during product size changes on a packaging line, eliminating the need to physically swap cylinders or bolt on external stoppers.
Light-Duty Clamping
Provides 402 N of push force at 0.5 MPa for securing small components or light assemblies, with the SUS304 rod offering corrosion resistance in mildly humid production areas.
Variable End Stops
Dial in the exact 170-190 mm travel distance required for diverting or positioning varying package sizes on a conveyor without reprogramming the entire pneumatic system.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-20 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires exact end-position tuning on the fly, such as during product changeovers on a packaging line. If you need greater clamping or thrust force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The 12 mm rod and M10x1.25 thread handle moderate side loads, but for this 190 mm stroke, external guidance is recommended if lateral forces are present.
For ISO 15552 interchangeability, match the 32 mm bore, 190 mm nominal stroke, 20 mm adjustment range, PT G1/8 port, and your required mounting set. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI 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 SAIJ32BX190-20 FAQ
At a 0.5 MPa operating pressure, the 32 mm bore generates 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm from the 190 mm nominal length, creating a 170-190 mm usable travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
