About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-20
The AirTAC SAIJ160X135-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 135 mm travel by up to 20 mm. This creates a precise 115-135 mm usable window, letting you finalize end positions at commissioning without adding external stops. It delivers substantial thrust, pushing with 14074 N and pulling with 9425 N at 0.7 MPa.
Built with a SUS304 stainless steel rod, this version is tailored for environments where corrosion resistance is paramount. The extruded aluminum barrel features sensor grooves on both sides, and while this specific SKU lacks a magnet, adding one enables compatibility with AirTAC CMSE reed and DMSE electronic sensors. The rear adjuster functions strictly as a travel stop to set deceleration, 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 SAIJ160BX135-20 Is Used
Machine Changeover
Dial in the 115-135 mm travel window during product size transitions to set new end stops without physically swapping the cylinder.
Corrosive Assembly
Utilize the SUS304 stainless steel rod in humid or washdown manufacturing areas where carbon steel rods would degrade.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-20 the Right Cylinder?
Choose the SAIJ adjustable-stroke format over a fixed SAI when you anticipate product changeovers or need to fine-tune machine setup without swapping hardware.
To replace an ISO 15552 cylinder, match the 160 mm bore, 135 mm stroke, PT tapered ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this series. Because the rear screw is just a stop, load-holding without live air requires a SAIL lock, BSAI clamp-lock, or external rod lock. Although 135 mm is a moderate stroke, the heavy 40 mm rod and M36x2 thread handle high side loads, yet an external guide is still recommended for rigid stability.
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 SAIJ160BX135-20 FAQ
The rear adjuster screw lets you shorten the 135 mm nominal stroke by up to 20 mm, creating a usable travel window of 115 to 135 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
