About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-100S
The AirTAC SAIJ160X900-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 800 to 900 mm usable travel window. Equipped with a SUS304 stainless steel rod and a -S magnet, it delivers 18095 N of push force at 0.9 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This heavy-duty pneumatic actuator uses PT G3/4 ports and M36x2 rod threads. The rear mechanical stopper lets you fine-tune the retract end position during commissioning without adding external stops. It supports AirTAC CMSE reed and DMSE electronic sensors to track piston position accurately.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-100S Is Used
Heavy Press Tuning
Dial in the exact 800-900 mm end position during heavy press commissioning without swapping cylinders or fabricating external stopper blocks.
Large Product Changeover
Adjust the retract distance on the fly to accommodate different large product sizes moving down an assembly conveyor line.
Automated Assembly Setup
Fine-tune the stroke end-point during automated assembly machine setup to perfectly seat large components without impact damage.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-100S the Right Cylinder?
Select this 160 mm bore actuator when an application demands high thrust, such as the 14074 N push force at 0.7 MPa, alongside a variable end-stop. If your setup requires less force, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa. For load-holding without live air pressure, note that the rear adjuster acts only as a travel stop and not a lock; consider an AirTAC SAIL or BSAI series cylinder for positive holding.
Because the 900 mm stroke is long, the 40 mm rod and M36x2 thread still require an external guide to manage side loads and prevent rod bending. This SAIJ model accepts a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 mounting interfaces.
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 SAIJ160BX900-100S FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 100 mm, creating a usable travel window of 800 to 900 mm. It only sets the travel end and does not lock the load without live air.
