About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-100S
The AirTAC SAIJ32X190-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated rear stroke adjuster. It provides a nominal 190 mm travel that can be dialed back by up to 100 mm, yielding a highly flexible 90-190 mm usable stroke window for precise end-position tuning at commissioning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks.
This variant incorporates a SUS304 stainless steel rod for superior corrosion resistance and ships with a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and the built-in magnet supports position sensing via CMSE reed or DMSE electronic switches. The rear adjustment screw acts purely as a mechanical stop to set the retract end-point, meaning it cannot hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-100S Is Used
Variable End-Stop Configuration
Ideal for testing fixtures where the retract position must be dialed back from 190 mm to 90 mm without physically swapping the cylinder or adding external stopper blocks.
Product Size Changeover
Enables rapid adjustment of the stroke window on packaging lines handling varying container sizes, allowing operators to fine-tune the 90-190 mm travel limit during format changes.
Corrosion-Resistant Positioning
The SUS304 stainless steel rod makes this 402 N thrust actuator suitable for light-duty machinery in wash-down or mildly corrosive environments requiring precise end-tuning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-100S the Right Cylinder?
Choose this 32 mm bore when a 402 N (0.5 MPa) thrust class fits your load, but your setup demands variable end-stops for rapid product changeovers instead of a fixed-stroke SAI cylinder. If your application requires greater force, stepping up to the 50 mm bore yields 982 N push at 0.5 MPa. Because the stroke is 190 mm, side-load risks are moderate, but an external guide remains advisable for heavy or off-center loads.
For a true ISO 15552 replacement match, verify the 32 mm bore, 190 mm nominal stroke, 100 mm adjustment range, PT G1/8 port, and the -S magnet. Remember that the rear adjuster and air cushions provide deceleration and positioning only; for fail-safe load-holding without live air, consider the SAIL or BSAI series. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ32BX190-100S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The operational speed range is 30-800 mm/s.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from 190 mm down to as little as 90 mm, creating a 90-190 mm usable window. It sets the retract end-position but does not lock or hold the load without continuous air pressure.
