About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-40
The AirTAC SAIJ32X195-40 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 195 mm stroke that can be dialed back by up to 40 mm, yielding a precise 155-195 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it fits compact automation setups requiring exact end-position tuning.
This variant features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, and fluid connections use a PT tapered G1/8 port. The rear adjustment screw acts purely as a mechanical stop to set the retract position and does not lock the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-40 Is Used
Changeover Calibration
Dial in the 155-195 mm travel window during product size changeovers without physically replacing the cylinder or adding shims.
End-Stop Trimming
Fine-tune the retract position at machine commissioning using the rear screw to perfect the picking or placing plane.
Variable Diverter Stroke
Adjust the actuation length on the fly for a conveyor diverter gate handling varying package depths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-40 the Right Cylinder?
Choose this 32 mm bore when an application demands precise end-stop tuning during commissioning or product changeover, avoiding the need to swap cylinders or bolt on external stops. If your setup requires higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa; conversely, dropping to a smaller bore reduces the footprint. Because this model lacks a magnet (-S), it cannot host CMSE or DMSE sensors without modification. For holding loads without continuous air pressure, an external rod lock or a related SAIL lock cylinder is required, as the adjuster is not a brake.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 195 mm stroke, 40 mm adjustment range, PT G1/8 port, and the SUS420J2 rod material. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. With a 195 mm stroke, the 12 mm rod handles moderate side loads, but an external guide is recommended for heavy off-center loads.

- ✓ 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 SAIJ32AX195-40 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from its 195 mm nominal length down to 155 mm. It sets the travel end but does not hold the load without live air pressure.
