About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-40S
The AirTAC SAIJ160X170-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 130-170 mm, allowing you to dial back the 170 mm nominal stroke by up to 40 mm during commissioning without adding external stops.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. It uses PT tapered ports, and the extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. The rear adjuster functions purely as a travel stop to set the end position, not as a lock to 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 SAIJ160BX170-40S Is Used
Heavy Press Fine-Tuning
Dial in the exact 130-170 mm retract position during machine setup to accommodate different material thicknesses without swapping out the entire cylinder.
Product Line Changeover
Quickly adjust the end-stop for varying product sizes on a conveyor line, using the 40 mm rear adjuster to shift the stroke window on the fly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-40S the Right Cylinder?
The adjustable stroke is ideal for product changeovers or variable end-stops, letting you fine-tune the retract position on the fly instead of physically swapping a fixed-stroke SAI cylinder. If your process requires true load-holding without continuous air pressure, this standard SAIJ will not suffice; you should look toward the SAIL (air-released lock) or BSAI (clamp-lock) series instead. For exact ISO 15552 mounting-interface replacement, match the 160 mm bore, 170 mm stroke, 40 mm adjustment, PT G3/4 ports, and the -S magnet requirement. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX170-40S FAQ
The rear adjuster allows you to shorten the effective stroke from its 170 mm nominal length down to 130 mm. This stopper sets the retract end position for fine-tuning but does not lock or hold the load without continuous air pressure.
