About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-75
The AirTAC SAIJ160X145-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 145 mm travel by up to 75 mm. This yields a usable 70-145 mm end-position window for fine-tuning at commissioning without swapping the cylinder or adding external stops.
Featuring a SUS304 stainless steel rod and PT tapered ports, this 160 mm bore unit delivers 10053 N of pull force at 0.5 MPa. The adjuster acts purely as a mechanical stop to set the retract end; it does not hold the load without live air. For position holding, consider SAIL or BSAI variants.

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 SAIJ160BX145-75 Is Used
Variable End-Stop Machining
Dial in the 70-145 mm retract window to position heavy machining heads accurately during setup or tooling changes.
Product Changeover
Quickly adjust the stroke stop on packaging conveyors to handle different package sizes without changing the cylinder.
Heavy Assembly Press
Use the 10053 N pull force and fine-tuned end position to seat large components precisely during automated assembly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-75 the Right Cylinder?
Choose this 160 mm bore when 10053 N pull force at 0.5 MPa is required, or step down to the 125 mm bore (5734 N pull) for lighter loads. The adjustable stroke is ideal for product changeovers requiring variable end-stops, unlike a fixed-stroke SAI cylinder.
When matching an ISO 15552 replacement, verify the 145 mm stroke, 75 mm adjustment, PT port threads, and SUS304 rod. For strokes of 145 mm, the 40 mm rod diameter handles side loads well, but an external guide is recommended for heavy unsupported loads.
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 SAIJ160BX145-75 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to trim the 145 mm nominal stroke back by up to 75 mm, creating a 70-145 mm usable travel window. It does not lock the load without live air.
