About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-50
The AirTAC SAIJ160X125-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel. With a nominal 125 mm stroke and a 50 mm adjustment range, you gain a usable travel window of 75 to 125 mm. This enables precise end-position tuning at commissioning or during product changeovers without swapping the cylinder or adding external stops.
This model features a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It uses a PT G3/4 port and operates at speeds of 30-500 mm/s. The rear adjuster acts strictly as a travel stop for deceleration, not a lock, meaning it will not hold a load safely without live air pressure.

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 SAIJ160BX125-50 Is Used
Heavy Press Tuning
Dial in the exact 75-125 mm travel window during machine commissioning to set precise pressing forces on heavy assemblies without external stopper blocks.
Product Size Changeover
Quickly adjust the retract end-position on a conveyor diverter when switching between different package sizes, using the 50 mm adjustment range to adapt on the fly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-50 the Right Cylinder?
If you need less force, stepping down to a 125 mm bore yields 6136 N, while stepping up to a 200 mm bore provides 15708 N. Choose this adjustable-stroke SAIJ over a fixed-stroke SAI when you need to dial in the exact end position during machine setup or accommodate varying product sizes on the same line. Because the stroke is 125 mm, an external guide is recommended if side loads are present.
For an exact ISO 15552 replacement match, verify the 160 mm bore, 125 mm stroke, 50 mm adjustment, PT G3/4 port, and the SUS304 rod material. Note that SAIJ uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR. If your application requires true load-holding without live air pressure, consider the SAIL or BSAI series instead, as this rear adjuster is not a brake.
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 SAIJ160BX125-50 FAQ
At its maximum rated pressure of 1.0 MPa, it can deliver up to 2050 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 125 mm down to as little as 75 mm, creating a 75-125 mm usable window. This stopper fine-tunes the retract end position but does not lock the load without live air pressure.
