About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX160-75
The AirTAC SAIJ160X160-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The rear adjustment mechanism allows you to trim the effective travel back by up to 75mm, creating a usable stroke window between 85 and 160mm without needing external stops.
This variant incorporates a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for tracking position. Note that the rear adjuster functions strictly as a travel stop to fine-tune end positions, not as a load-holding lock; true load holding without live air pressure requires a related SAIL or BSAI series cylinder.

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 SAIJ160BX160-75 Is Used
Machine Setup & Changeover
Dial in the 85-160mm travel window during line changeovers to accommodate new product dimensions without physically swapping out the entire cylinder assembly.
Variable End-Stop Positioning
Fine-tune the retract end-position precisely at commissioning, using the rear stopper to absorb mechanical tolerances rather than adding external hard stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX160-75 the Right Cylinder?
Select this 160mm bore cylinder when an application requires high thrust (up to 18095N at 0.9 MPa) alongside flexible end-position tuning during commissioning or product changeover. If your process demands less force, stepping down to the 125mm bore yields 8590N at 0.7 MPa, whereas moving up to the massive 200mm bore provides 21991N at the same pressure. The adjustable rear stopper is ideal for dialing in exact end-of-stroke positions on the fly, a distinct advantage over a fixed-stroke SAI model.
When matching an ISO 15552 replacement, verify the 160mm bore, 160mm stroke, 75mm adjustment range, PT port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This specific configuration omits the FB, CA, CB, and CR mounts. Because the total stroke is 160mm, side-load is minimal, but for any stroke exceeding 300mm, an external guide is highly recommended to protect the rod from deflection.
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 SAIJ160BX160-75 FAQ
The rear adjuster acts as an external stopper that lets you shorten the nominal 160mm stroke by up to 75mm. This creates a usable travel window of 85 to 160mm, allowing precise end-position tuning at commissioning without changing the cylinder.
