About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-75
The AirTAC SAIJ160X170-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated rear stopper allows you to fine-tune the effective travel down from the 170mm nominal stroke, providing a usable adjustment window of 95-170mm without requiring external stops.
This adjustable capability is ideal for machines processing varying product sizes, enabling rapid commissioning and changeovers. The extruded aluminum barrel features sensor grooves on both sides, and the unit supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) while omitting FB, CA, CB, and CR mounts. It operates at speeds of 30-500mm/s.

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 SAIJ160BX170-75 Is Used
Variable Product Changeovers
Ideal for packaging lines that process different carton sizes, allowing operators to shorten the retract stroke from 170mm down to 95mm to accommodate varying product lengths on the fly.
Actuator Position Trimming
Replaces the need to swap cylinders when actuator travel needs slight reduction, using the 75mm adjustment range to fine-tune the stroke without adding bulky external stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-75 the Right Cylinder?
Select this 160mm bore cylinder when an application requires high thrust (up to 18095N at 0.9 MPa) alongside flexible end-positioning. If your changeover requirements are smaller, stepping down to a 125mm bore yields 8590N at 0.5 MPa. Choose this SAIJ model over a fixed-stroke SAI when you need to dial in the retract position during setup. 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 an external rod lock or the SAIL/BSAI series. This configuration features a PT tapered port thread and a SUS304 stainless steel 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 SAIJ160BX170-75 FAQ
At 0.9 MPa, the push force increases to 18095N.
The rear adjuster acts as a mechanical stop that trims the retract stroke. For this 170mm nominal stroke cylinder, the -75 code means you can reduce the effective travel anywhere within a 95-170mm window. The adjuster only sets the travel end and does not lock or hold the load without live air pressure.
