About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX90-50S
The AirTAC SAIJ32X90-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel by up to 50 mm. This creates a 40-90 mm usable window on the 90 mm base stroke, enabling precise end-position tuning at commissioning without swapping hardware.
This variant includes a piston magnet for CMSE or DMSE sensors and uses a SUS420J2 stainless steel rod for improved corrosion resistance. The extruded aluminum barrel integrates sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX90-50S Is Used
Machine Setup Tuning
Dial in the exact 40-90 mm travel limit during commissioning to perfect end positions without adding external stopper blocks.
Product Size Changeover
Quickly adapt the stroke window on packaging lines when running different package lengths, saving changeover time.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX90-50S the Right Cylinder?
The 50 mm adjustment range is ideal for machine setups requiring variable end stops or product-size changeovers, offering finer control than a fixed-stroke SAI cylinder. To match this ISO 15552 replacement exactly, specify 32 mm bore, 90 mm stroke, 50 mm adjustment, PT ports, and the -S magnet.
The rear adjuster acts purely as a mechanical stop to set travel limits and does not hold the load without live air pressure. For fail-safe load holding, consider an external rod lock or the SAIL/BSAI series.
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 SAIJ32AX90-50S FAQ
The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 90 mm nominal stroke by up to 50 mm, providing a usable travel window of 40-90 mm. It functions as a mechanical stop for position tuning, not as a load lock.
