About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-30
The AirTAC SAIJ160X190-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from the 190 mm nominal stroke, providing a precise 160-190 mm usable window. Belonging to the 160 mm bore class, it delivers 10053 N of pull force at 0.5 MPa and reaches a maximum of 18095 N at 0.9 MPa. This substantial thrust capacity makes it highly suitable for heavy-duty mold handling and large press operations.
This specific SKU is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments, alongside PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. It is important to note that the rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-30 Is Used
Heavy Press Tuning
Dial in the exact 160-190 mm travel window during heavy press commissioning without adding external mechanical stops.
Mold Changeover
Accommodate varying mold sizes on a single line by adjusting the rear stopper, drastically reducing machine setup time.
Corrosive Forming
Leverage the SUS304 stainless steel rod for large-part forming tasks in humid or chemically exposed manufacturing cells.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-30 the Right Cylinder?
Select this 160 mm bore cylinder when an application demands high force combined with on-the-fly end-position tuning, avoiding the need to physically swap out a fixed-stroke SAI cylinder during product changeovers. If your process requires less force, stepping down to a 125 mm bore yields 5734 N of pull at 0.5 MPa, whereas stepping up to a 200 mm bore provides 15080 N of pull. Because the 190 mm stroke is well under the 1500 mm maximum standard stroke for this bore, it is a standard catalog item.
When matching ISO 15552 interchangeability dimensions, ensure your setup accounts for the PT port threads and the reduced SAIJ mounting set, which includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets (omitting FB, CA, CB, and CR). Although this stroke length does not strictly require external guiding, the robust 40 mm rod and M36x2 thread handle significant side loads, and the cylinder operates at a controlled speed range of 30-500 mm/s.
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 SAIJ160 Adjustable Cylinder SAIJ160BX190-30 FAQ
The rear adjusting screw allows you to mechanically shorten the 190 mm nominal stroke by up to 30 mm, creating a usable travel window of 160-190 mm. This stopper sets the end position but does not lock the load without live air pressure.
