About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX150-30S
The AirTAC SAIJ160X150-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel down to a 120-150 mm window from its 150 mm nominal length. Built with a robust 40 mm SUS304 stainless steel rod and PT tapered ports, it delivers massive thrust up to 18095 N at 0.9 MPa. This makes it ideal for heavy-duty tasks requiring exact end-position tuning without swapping components.
Unlike a fixed-stroke SAI, the external stopper screw allows precise end-position adjustments during commissioning or product changeover. The adjuster acts purely as a travel stop and works with the variable air cushions to decelerate the load, but it will not hold the load without live air pressure. For load-holding needs, consider the SAIL or BSAI series. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet integrates seamlessly with CMSE reed and DMSE electronic sensors.

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 SAIJ160BX150-30S Is Used
Heavy Machinery Positioning
Dial in the exact 120-150 mm retract stop during heavy machinery assembly to accommodate varying material thicknesses without re-engineering the fixture.
Automated Press Tuning
Fine-tune the end-of-stroke position on automated pressing lines to adjust compression depth safely within the 30 mm adjustment window.
Modular Tooling Changeover
Rapidly adapt machine stops during product size changeovers, using the rear adjuster to set new endpoints rather than installing fixed spacers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX150-30S the Right Cylinder?
Select this 160 mm bore cylinder when an application demands high force—stepping down to a 125 mm bore yields 11045 N at 0.9 MPa, whereas this SAIJ160X150-30-S provides 18095 N. Choose the adjustable-stroke SAIJ over a fixed SAI when you need a variable end-stop to fine-tune the retract position on the fly. Ensure your setup matches the configuration: a 150 mm stroke, 30 mm adjustment, PT ports, and a -S magnet. Because the stroke is 150 mm, side-load risks are moderate, but you should still use an external guide to prevent rod binding.
When replacing an ISO 15552 cylinder, verify the 160 mm bore, 150 mm stroke, PT port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable series. The 40 mm SUS304 rod handles high side loads better than standard carbon steel, though long unsupported strokes always require external guidance.

- ✓ 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 SAIJ160BX150-30S FAQ
The rear adjuster screw allows you to shorten the 150 mm nominal stroke by up to 30 mm, creating a usable travel window of 120-150 mm. This stopper sets the travel end and relies on the air cushion for deceleration, but it does not lock or hold the load without continuous air pressure.
