About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX185-75
The AirTAC SAIJ160X185-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 110-185mm, allowing you to dial back the 185mm nominal stroke by up to 75mm during commissioning.
This model uses a SUS304 stainless steel piston rod (option B), offering superior corrosion resistance compared to standard carbon steel. The fluid porting utilizes PT tapered threads. The rear adjuster functions purely as a travel stop to fine-tune the end position and decelerate the load; it does not lock or 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 SAIJ160BX185-75 Is Used
Machine Changeover
Quickly adapt the retract end-stop for different product sizes on a packaging line without replacing the cylinder or bolting on external stops.
Precision End-Positioning
Fine-tune the 110-185mm travel window during initial commissioning to achieve exact material placement and compensate for mechanical tolerances.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX185-75 the Right Cylinder?
Select this 160mm bore cylinder when an application requires high thrust—such as the 10053N pull force at 0.5 MPa—combined with variable end-stop positioning. The 75mm adjustment range is ideal for product changeovers on a line, letting operators shift the retract position without swapping the cylinder or adding external stops.
For load-holding without continuous live air, a standard SAIJ is insufficient because the rear adjuster and air cushions only set travel ends, not hold loads. In those cases, consider an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder. This SAIJ uses PT ports and supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ160BX185-75 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 2050 kgf of push force.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from the nominal 185mm down to 110mm. This creates a 75mm adjustable travel window for fine-tuning the retract position without changing the cylinder's physical mounting.
