About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-30S
The AirTAC SAIJ160X270-30-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, providing a usable travel window of 240 to 270 mm. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This model uses PT tapered port threads and features variable air cushions at both ends to manage kinetic energy. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops; it does 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 SAIJ160BX270-30S Is Used
End-Position Tuning
Dial in the exact retract distance within the 240-270 mm window during machine commissioning without swapping cylinders.
Product Changeover
Quickly adjust the stroke stop on a packaging line to handle different carton sizes or material thicknesses.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-30S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring exact end-position tuning across a 240-270 mm window. For any load holding without live air, select the SAIL or BSAI series instead, as the SAIJ adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 270 mm nominal stroke, 30 mm adjustment, PT port threads, and the -S magnet requirement. Because the 270 mm stroke is substantial, ensure external guiding is used to prevent excessive side-loading on the SUS304 rod. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, 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 SAIJ160BX270-30S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, creating a usable travel window of 240 to 270 mm. This mechanical stop fine-tunes the retract end position but does not lock the load without continuous air pressure.
