About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-40
The AirTAC SAIJ160X135-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 95 to 135 mm, allowing you to dial back the 135 mm nominal stroke by up to 40 mm during commissioning. Delivering a robust 9425 N pull force at 0.5 MPa, it is built for heavy-duty positioning.
This unit features a SUS304 stainless steel rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember the rear adjuster acts only as a travel stop, not a load lock, so live air pressure is required to hold position.

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 SAIJ160BX135-40 Is Used
End-Position Tuning
Fine-tune the retract stroke precisely during machine setup without adding external stops or changing the cylinder.
Product Changeover
Quickly adjust the travel window from 95 to 135 mm to accommodate different product sizes on the same line.
Heavy-Duty Positioning
Leverage the 9425 N pull force for moving substantial masses while using the rear screw to set exact stopping points.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-40 the Right Cylinder?
Choose this 160 mm bore when you need higher thrust than the 125 mm bore (5734 N pull at 0.5 MPa) but less than the massive 200 mm class. The adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for product changeovers without swapping components. Since the total stroke is 135 mm, an external guide is recommended for side-load stability. For load-holding without live pressure, consider an external rod lock or the SAIL 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 SAIJ160 Adjustable Cylinder SAIJ160BX135-40 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 2050 kgf.
The rear adjuster screw lets you shorten the 135 mm nominal stroke by up to 40 mm, creating a usable travel window of 95 to 135 mm. It acts as a mechanical stop and does not lock the load without air pressure.
