About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-75
The AirTAC SAIJ160X140-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits on-the-fly end-position tuning. By dialing the external stopper, you achieve a usable travel window between 65 and 140 mm without adding external stops.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT G3/4 tapered ports. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear screw acts purely as a mechanical travel stop for deceleration, meaning it will not hold a load safely 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 SAIJ160BX140-75 Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 65-140 mm window during machine setup, avoiding the need to physically swap cylinders when product dimensions change.
Corrosion-Resistant Tooling
Rely on the SUS304 stainless steel rod in environments where moisture or coolant spray would degrade standard carbon steel rods.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX140-75 the Right Cylinder?
An adjustable-stroke cylinder is selected over a fixed-stroke SAI when you need to fine-tune the retract end-position during commissioning or product changeovers. Since this model has a 140 mm stroke, an external guide rail is recommended to manage side loads and prevent rod binding.
For direct interchangeability, match the 160 mm bore, 140 mm nominal stroke, 75 mm adjustment range, PT G3/4 ports, and mounting interface. This SAIJ series supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set, omitting the FB, CA, CB, and CR options. Because it lacks an -S magnet specification, position sensing requires external confirmation.
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 SAIJ160BX140-75 FAQ
The rear adjuster acts as a mechanical stop that trims the effective travel. For this model, you can shorten the 140 mm nominal stroke by up to 75 mm, creating a usable travel window of 65 to 140 mm. It only sets the end position and does not lock the load without live air.
The maximum thrust is 2050 kgf at 1.0 MPa.
