About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX105-30S
The AirTAC SAIJ160X105-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 75-105 mm, allowing you to dial back the 105 mm nominal stroke by up to 30 mm during commissioning. In the 160 mm bore class, it delivers a substantial 10053 N pull force at 0.5 MPa and reaches a maximum of 2050 kgf at 1.0 MPa.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel includes sensor grooves on both sides. It uses PT tapered port threads and operates at speeds of 30-500 mm/s, supported by 50 mm air cushions at both ends.

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 SAIJ160BX105-30S Is Used
Variable End Stops
Fine-tune the 75-105 mm travel window on the fly to accommodate multiple product sizes on the same line without mechanical rebuilds.
Machine Changeover
Quickly dial in the exact retract position during product changeover, using the rear stopper to set precise end-of-stroke coordinates.
Heavy Assembly Pressing
Leverage the 10053 N pull force at 0.5 MPa for heavy-duty pressing and holding tasks, adjusting the final 30 mm of travel for part variance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX105-30S the Right Cylinder?
Select this adjustable-stroke model when your machine setup requires variable end stops or fine end-position tuning without swapping cylinders or adding external stops. The robust M36x2 rod thread handles high side loads, but even with a sturdy rod, any stroke of 300 mm or more requires an external guide. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series.
For ISO 15552 dimensionally interchangeable replacements, match the 160 mm bore, 105 mm stroke, 30 mm adjustment, PT G3/4 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.
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 SAIJ160BX105-30S FAQ
It reaches a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 105 mm nominal stroke by up to 30 mm. This creates a 75-105 mm usable travel window for fine-tuning end positions without replacing the cylinder.
