About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-40S
The AirTAC SAIJ32X170-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 170 mm stroke that can be fine-tuned down by up to 40 mm, yielding a usable travel window of 130-170 mm to perfectly dial in retract end positions.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and ships with a magnetic piston (-S) for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and fluid supply is routed through PT tapered G1/8 ports. The rear adjuster functions strictly as a travel stop for deceleration and positioning, not as a load-holding lock.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 Adjustable Cylinder SAIJ32 SAIJ32BX170-40S Is Used
End-Position Tuning
Dial in the exact retract distance within the 130-170 mm window during machine commissioning to accommodate varying workpiece lengths without external stops.
Product Changeover
Quickly adjust the stroke by up to 40 mm on packaging lines when switching between different product sizes, minimizing downtime.
Corrosive Positioning
Leverage the SUS304 stainless steel rod for precise component positioning tasks in environments where standard carbon steel rods would degrade.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-40S the Right Cylinder?
Select this 32 mm bore adjustable cylinder when an application requires exact end-position tuning during commissioning or product changeover without swapping out physical components. Because this model features a 170 mm stroke, it remains well within the 1000 mm maximum standard stroke limit for this bore size.
The -40 mm adjustment window is ideal for accommodating minor dimensional variances in workpieces. For holding a load securely without live air pressure, this cylinder is insufficient since the rear screw is only a stop—you would need to specify a SAIL pneumatic lock or an external rod lock. This SAIJ configuration includes a -S magnet, PT ports, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, ensuring seamless dimensional interchangeability with ISO 15552 cylinders.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX170-40S FAQ
At the maximum 1.0 MPa pressure, it achieves 82 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from its 170 mm nominal length down to 130 mm. It is a travel stop for setting end positions, not a lock, and does not hold the load without continuous air pressure.
