About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-40S
The AirTAC SAIJ32X195-40-S 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 fine-tuned backward by up to 40 mm, creating a precise 155-195 mm usable travel window for product changeovers. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa operating pressure.
This adjustable-stroke variant omits the FB, CA, CB, and CR mounts, utilizing a reduced set of ISO 15552 attachments (Basic, FA, LB, TC, FTC, TCM1, TCM2). It features a SUS420J2 stainless steel rod for improved corrosion resistance and includes a magnetic piston for CMSE reed and DMSE electronic sensors. The fluid port utilizes a PT tapered thread, and the extruded aluminum barrel integrates sensor grooves on both lateral sides.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-40S Is Used
Machine Changeover
Dial in the 155-195 mm travel window to accommodate different product lengths on the same line without physically swapping cylinders.
End-Position Tuning
Use the rear stopper screw to fine-tune the exact retracted position during commissioning, eliminating the need for external mechanical spacers.
Light Assembly Automation
Leverage the 402 N push force at 0.5 MPa for precise pressing and locating tasks where a variable end-stop is required for flexibility.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-40S the Right Cylinder?
Choose this 32 mm bore when your application requires the 402 N push force at 0.5 MPa, stepping down from the 40 mm bore which offers 628 N. The rear adjusting screw allows you to dial in the exact end-of-travel position during commissioning without swapping the cylinder or adding external stops. For fixed travel requirements without the need for end-position tuning, the standard SAI series is the alternative.
Because this is a 195 mm stroke, the 12 mm diameter carbon steel rod and M10x1.25 thread can handle moderate side loads, but long unsupported strokes still require an external guide to prevent binding. The rear adjuster acts solely as a travel stop and deceleration point; it does not hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series. Replacement matches require 32 mm bore, 195 mm stroke, 40 mm adjustment, PT port, and the -S magnet.
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 SAIJ32AX195-40S FAQ
At 0.5 MPa it 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 allows you to shorten the 195 mm nominal stroke by up to 40 mm, providing a usable travel window of 155-195 mm to fine-tune the end position without replacing the cylinder.
