About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-100S
The AirTAC SAIJ32X185-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 85-185 mm usable travel window by trimming the nominal 185 mm stroke up to 100 mm. In the 32 mm bore class, it generates 402 N of push force and 345 N of pull force at 0.5 MPa. The integrated magnet works directly with AirTAC CMSE reed and DMSE electronic sensors.
This adjustable-stroke model uses a PT tapered port and features a SUS420J2 stainless steel rod for improved corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides. Mounting options cover the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster functions as a travel stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-100S Is Used
Machine Changeovers
Dial in the exact retract position during product size changes without swapping cylinders or bolting on external stops.
End-Position Tuning
Fine-tune the 85-185 mm travel window at commissioning to perfect the stroke end-point for delicate operations.
Adjustable Assembly Jigs
Set variable end-stops on automated assembly lines where multiple parts require different retract distances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-100S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa. If your setup needs less force, stepping down is an option, but stepping up to a 40 mm bore yields 628 N push force for heavier loads. The 100 mm adjustment window is ideal for machine changeovers, allowing you to fine-tune the retract end position without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on the adjuster. This SKU uses a PT port, SUS420J2 rod material, and includes a magnet (-S) for position sensing.
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 Adjustable Cylinder SAIJ32 SAIJ32AX185-100S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the nominal 185 mm stroke back by up to 100 mm, creating a usable travel window of 85 to 185 mm. It only sets the end position; it does not lock or hold the load without live air pressure.
