About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-30S
The AirTAC SAIJ160X190-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end-position by up to 30 mm. This specific configuration yields a usable travel window of 160 to 190 mm, letting you dial in the exact end-stop during commissioning without adding external physical stops or swapping the entire barrel.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and is built with a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports position detection via AirTAC CMSE reed or DMSE electronic solid-state switches. It utilizes the standard SAIJ mounting subset—Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting the FB, CA, CB, and CR options.

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 SAIJ160BX190-30S Is Used
Machine Changeover
Dial in the retract stop by up to 30 mm during product size changes on a packaging line without physically swapping the cylinder or adding external stopper blocks.
Press End-Tuning
Fine-tune the exact end-position of a high-force pressing operation at commissioning, using the 160-190 mm travel window to set precise contact depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-30S the Right Cylinder?
Select this 160 mm bore adjustable-stroke cylinder when your machinery requires high thrust combined with variable end-position tuning for product changeovers. If 14074 N at 0.7 MPa is excessive, stepping down to a 125 mm bore yields 8590 N; if you need more force, a 200 mm bore provides 21991 N. Choose this SAIJ variant over a fixed-stroke SAI when you need on-the-fly end-position adjustments rather than a rigid stop. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true fail-safe load holding, consider an SAIL or BSAI cylinder instead.
Because the 190 mm stroke is relatively short for this large bore, side-load risks are manageable, but you should still ensure the M36x2 rod thread and 40 mm rod diameter are properly guided to prevent binding. The PT port and G3/4 thread size must be matched to your pneumatic supply. When replacing an ISO 15552 cylinder, verify the 160 mm bore, 190 mm stroke, 30 mm adjustment range, PT port, and the -S magnet requirement.

- ✓ 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 SAIJ160BX190-30S FAQ
At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm. For this 190 mm nominal stroke cylinder, this creates an adjustable travel window of 160 to 190 mm. The adjuster only sets the travel end and does not lock or hold the load without continuous air pressure.
