About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX185-10S
The AirTAC SAIJ160X185-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning. Its 185 mm nominal stroke can be dialed back by up to 10 mm, providing a usable travel window of 175-185 mm without swapping out the unit.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. It uses PT tapered ports sized at G3/4, and the extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to set deceleration and travel limits, meaning it will not 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 SAIJ160BX185-10S Is Used
Machine Setup Tuning
Dial in the exact 175-185 mm travel window during initial commissioning to perfect heavy press end-stops without machining new hard stops.
Product Changeover
Quickly adjust the retract end-position on a packaging line when switching product sizes, saving downtime on the factory floor.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX185-10S the Right Cylinder?
The 10 mm adjustable stroke window is ideal for product changeovers where exact end-position tuning is necessary, avoiding the need to bolt on external stops or buy a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, this cylinder is insufficient; the rear stop is not a lock, so you would need to step up to an SAIL (air-released lock) or BSAI (clamp-lock) actuator instead.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 185 mm stroke, 10 mm adjustment range, G3/4 PT ports, and the -S magnet requirement. Because the stroke is under 300 mm, side-load risks are moderate, but the 40 mm rod diameter and M36x2 thread handle higher bending stress well; still use an external guide for heavy lateral loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.
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 SAIJ160BX185-10S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the 185 mm nominal stroke by up to 10 mm, creating a usable travel window of 175-185 mm. It only sets the travel end and deceleration; it does not lock or hold the load without live air pressure.
