About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX115-20
The AirTAC SAIJ160X115-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning. It features a 160 mm bore and a 115 mm nominal stroke that can be dialed back by up to 20 mm, creating a precise 95-115 mm usable travel window without needing external stops. Built with an SUS304 stainless steel rod and PT tapered ports, it delivers robust performance in demanding environments.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. You can use AirTAC CMSE reed or DMSE electronic sensors, though this specific SKU does not include a magnet. The rear adjuster acts purely as a travel stop for deceleration and positioning, not as a lock to hold the load 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 SAIJ160BX115-20 Is Used
Heavy Press Tuning
Dial in the exact 95-115 mm travel window during heavy press commissioning to accommodate material thickness variations without changing the cylinder.
Product Size Changeover
Quickly adjust the rear stopper for different product sizes on a high-force assembly line, reducing machine setup downtime.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX115-20 the Right Cylinder?
The adjustable stroke is perfect for product-size changeovers on a line, letting you dial in the exact 95-115 mm travel window on the fly instead of swapping out a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, you would need to integrate an external rod lock or look at the SAIL or BSAI series, as the SAIJ adjuster is only a stop.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 115 mm stroke, PT port thread, and your required mounting style. SAIJ supports a specific subset of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because this model features a large 40 mm rod and M36x2 thread, it handles high side loads well, but any application approaching the maximum stroke range should still use an external guide to prevent premature wear.
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 SAIJ160BX115-20 FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 20 mm. This creates a usable stroke window of 95 to 115 mm, letting you fine-tune the end position at commissioning without adding external stops.
At 0.9 MPa, the push force is 18095 N and the pull force is 9425 N.
