About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-30
The AirTAC SAIJ160X155-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position without external stops. It provides a usable travel window of 125 to 155 mm, giving you 30 mm of flexibility to dial in the retract distance during machine commissioning.
Built with a SUS304 stainless steel rod, this variant withstands corrosive environments while handling high side loads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. It uses PT tapered ports and features adjustable air cushions at both ends to manage kinetic energy, though the adjuster acts only as a travel stop and 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 SAIJ160BX155-30 Is Used
Machine Changeover
Dial in the 125-155 mm retract position during product size changes without physically swapping cylinders or adding external mechanical stops.
Corrosive Positioning
The SUS304 stainless steel rod handles harsh washdown environments while providing a robust 40 mm diameter to support high side loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-30 the Right Cylinder?
If your setup needs less force, stepping down to a 125 mm bore yields 6136 N at 0.5 MPa, whereas moving up to a 200 mm bore provides 15708 N. The adjustable stroke is ideal for product changeovers on a line, allowing you to shorten the travel from 155 mm down to 125 mm without swapping the cylinder.
For direct compatibility, match the ISO 15552 mounting dimensions, the PT G3/4 port, and the 155 mm stroke. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting FB, CA, CB, and CR. Because this cylinder lacks a lock, it cannot hold a load without live air; for fail-safe holding, consider the SAIL or BSAI series. For any stroke of 300 mm or more, always use an external guide to prevent excessive side loading on the rod.
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 SAIJ160BX155-30 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm, providing a usable travel window of 125 to 155 mm. It acts as a physical stop to fine-tune the retract position and works alongside the air cushions, but it does not lock the load without live air pressure.
At the maximum operating pressure of 1.0 MPa, the push force reaches 2050 kgf.
