About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-100
The AirTAC SAIJ160X135-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 10053N push force at 0.5MPa and provides a usable travel window of 35 to 135mm, letting you dial back the nominal 135mm stroke by up to 100mm during setup. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
This heavy-duty actuator utilizes a 40mm carbon steel rod with an M36x2 thread, paired with 50mm air cushions at both ends to manage heavy end-of-travel impacts. The rear adjustment screw functions purely as a mechanical stop to set the retract position and deceleration point, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-100 Is Used
Heavy Press Changeovers
Dial in the exact 35-135mm end-stop for heavy pressing and forming tasks during rapid product size changeovers on the factory floor.
Variable Assembly Stops
Fine-tune the retract position on automated assembly lines to accommodate multiple part lengths without physically swapping actuators.
Machine Commissioning
Trim the effective travel during initial machine commissioning to prevent mechanical interference and dial in precise end-position timing.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-100 the Right Cylinder?
Choose this 160mm bore actuator when you need extreme fine-tuning over a wide 35-135mm travel band without swapping out physical cylinders during product changeovers. If your application requires less thrust, stepping down to the 125mm bore yields 6136N of push force at 0.5MPa, whereas moving up to the 200mm bore provides 15708N. Because this SKU features a 135mm stroke, the 40mm rod diameter provides excellent resistance to side-loading, though any long unsupported loads should still use an external guide.
For an exact ISO 15552 dimensional replacement, match the 160mm bore, 135mm stroke, 100mm adjustment range, PT G3/4 port thread, and your required mounting accessory from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the SAIJ series omits FB, CA, CB, and CR mounts. If your process requires true load-holding without continuous air pressure, this cylinder's adjuster is insufficient; consider the SAIL series with an air-released lock or an external pilot-operated check valve.

- ✓ 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 SAIJ160X135-100 FAQ
At an operating pressure of 0.5MPa, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At 0.9MPa, the push force increases to 18095N.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 135mm stroke by up to 100mm, creating a usable travel window of 35 to 135mm. It only sets the end position and deceleration; it does not lock or hold the load without live air pressure.
