About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-100S
The AirTAC SAIJ160X260-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 160-260mm usable travel window. Built with a SUS304 stainless steel rod (option B) and a PT tapered port, it delivers 14074N of push force at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
Equipped with a magnet (-S), this unit supports AirTAC CMSE reed and DMSE electronic solid-state sensors. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It is not a lock; for load-holding without live air pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-100S Is Used
Product Changeover
Quickly fine-tune the retract end-stop during product size changes on a packaging line without replacing the cylinder or bolting on external stops.
Heavy Press Fit
Delivers 14074N of push force at 0.7 MPa for driving heavy assemblies, while the 100mm adjustment window allows precise positioning of the press fit.
Machine Setup
Dial in the exact 160-260mm travel distance during machine commissioning to perfect the stroke end-position for delicate operations.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-100S the Right Cylinder?
Choose this 160mm bore cylinder when an application requires high thrust (up to 10053N at 0.5 MPa) alongside variable end-position tuning. If you need less force, stepping down to a 125mm bore yields 6136N at 0.5 MPa, while moving up to a 200mm bore provides 15708N at 0.5 MPa. An adjustable stroke is ideal for product changeovers on a line, allowing you to dial in the exact retract distance without swapping the cylinder.
When replacing an ISO 15552 cylinder, match the 160mm bore, 260mm stroke, 100mm adjustment, PT port thread, and the -S magnet. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. With a 40mm rod and M36x2 thread, it handles high side loads, but any stroke over 300mm still requires an external guide.
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 SAIJ160BX260-100S FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder generates 14074N of push force and 9425N of pull force. At the maximum 1.0 MPa pressure, it reaches 2050 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 260mm nominal stroke by up to 100mm, providing a usable travel window of 160-260mm. It only sets the travel end and does not hold the load without live air.
