About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-30
The AirTAC SAIJ160X140-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 110 to 140 mm. The extruded aluminum barrel features sensor grooves on both sides, although this specific unit ships without a magnet for position detection.
This configuration incorporates a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in harsh environments. The rear adjustment screw functions strictly as a mechanical stop to fine-tune the retract end position during commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements, a SAIL or BSAI series cylinder should be specified instead.

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 SAIJ160BX140-30 Is Used
Machine Setup Tuning
Dial in the exact 110 to 140 mm retract position during initial commissioning without machining custom spacers.
Product Changeover
Quickly adjust the end-stop to accommodate different material thicknesses on a single production line.
Corrosive Environments
Leverage the SUS304 stainless steel rod for reliable high-force actuation in washdown or chemical areas.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-30 the Right Cylinder?
The adjustable stroke is ideal for applications requiring variable end-stops or product changeovers, avoiding the need to physically swap cylinders or bolt on external stops. As an ISO 15552 interchangeable cylinder, ensure your replacement matches the 160 mm bore, 140 mm stroke, 30 mm adjustment, PT G3/4 port, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the stroke is relatively short at 140 mm, side-load stress on the 40 mm rod is minimal, though external guides are always recommended for heavy radial loads. Note that the rear adjuster and variable air cushions only decelerate the travel end; they are not brakes. If the process requires the cylinder to hold a suspended load without continuous air, utilize an external pilot-operated check valve or a BSAI clamp-lock model.
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 SAIJ160BX140-30 FAQ
The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from the nominal 140 mm down to 110 mm. It is used for fine-tuning end positions at commissioning without altering the air cushions or mounting.
