About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-50S
The AirTAC SAIJ32X90-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 90 mm nominal stroke to a 40 mm minimum. This creates a highly versatile 40-90 mm usable window, letting you dial in the exact end position during commissioning without swapping out the unit.
This specific SKU is built with a SUS304 stainless steel rod for superior corrosion resistance, includes a PT tapered port thread, and comes with a magnet for position sensing. You can pair the internal magnet with AirTAC CMSE reed or DMSE electronic solid-state switches mounted into the dual-side sensor grooves on the extruded aluminum barrel.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ32BX90-50S Is Used
Machine Changeover
Dial the rear stopper back by up to 50 mm to instantly accommodate a new shorter product length on a packaging line without changing the cylinder.
End-Position Tuning
Fine-tune the retract stroke during commissioning to achieve exact 40-90 mm travel limits, ensuring precise mechanical alignment without external shims.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-50S the Right Cylinder?
If your setup demands higher thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. The 50 mm adjustment range is ideal for machines handling multiple product sizes, acting as a variable end-stop. Remember that the rear adjuster functions purely as a mechanical stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series.
As a dimensionally interchangeable ISO 15552 cylinder, this model accepts PT port threads and the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 90 mm stroke is under 300 mm, side-load stress is minimal, though you should still ensure axial load alignment to maximize seal life.

- ✓ 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 SAIJ32BX90-50S FAQ
If you increase the supply to 0.7 MPa, the push force rises to 563 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 90 mm nominal stroke by up to 50 mm, creating a usable travel window of 40-90 mm. It requires live air to move and does not lock or hold the load in place.
