About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-50S
The AirTAC SAIJ32X195-50-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 50 mm, establishing a usable travel window of 145-195 mm. Within its 32 mm bore, it generates 402 N of push force and 345 N of pull force at 0.5 MPa operating pressure.
This variant includes a SUS420J2 stainless steel rod for improved corrosion resistance and a magnetic piston for position sensing. It accepts reed-based CMSE and solid-state DMSE switches mounted into the dual-side sensor grooves of the extruded aluminum barrel. The rear adjuster acts purely as a travel stop to dial in end positions during commissioning; it does not lock or hold the load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-50S Is Used
Machine Changeover
Dial in the 145-195 mm travel window during product size transitions without physically replacing the cylinder or bolting on external stops.
End-Position Tuning
Use the 50 mm rear adjuster to precisely set the retraction end-point during commissioning, absorbing mechanical tolerances in the fixture.
Sensor Integration
Leverage the magnetic piston and dual sensor grooves to mount CMSE or DMSE switches for exact intermediate position feedback.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-50S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your setup requires exact end-position tuning without adding external stops or swapping cylinders during product changeovers. If your application needs greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. To secure a drop-in ISO 15552 replacement, verify the 195 mm stroke, 50 mm adjustment range, PT tapered port threads, and the -S magnet option.
Because the nominal stroke is 195 mm, the 12 mm diameter rod and M10x1.25 thread provide moderate side-load capacity, but an external guide is recommended for heavy or off-center loads. For applications requiring true load-holding without live air pressure, consider the AirTAC SAIL or BSAI series, as the SAIJ adjuster and air cushions function only as travel stops and deceleration devices.

- ✓ 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 SAIJ32AX195-50S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It operates at speeds between 30 and 800 mm/s, featuring variable air cushions at both ends.
The rear adjuster acts as a mechanical stopper that can shorten the effective stroke by up to 50 mm. This turns the 195 mm nominal stroke into a 145-195 mm adjustable travel window for fine-tuning end positions without changing the cylinder.
