About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-50
The AirTAC SAIJ32X375-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel by up to 50 mm, creating a 325-375 mm usable window. The extruded aluminum barrel includes sensor grooves on both sides.
This specific SKU is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threads. The rear adjuster acts strictly as a mechanical stop to fine-tune the retract end position during commissioning; it is not a lock and cannot hold a load without live air pressure.

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 SAIJ32BX375-50 Is Used
End-Stop Calibration
Dial in the exact retract position within the 325-375 mm window during machine commissioning without adding external stops.
Product Changeover
Quickly adjust the stroke length by up to 50 mm to accommodate different product sizes on a packaging line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-50 the Right Cylinder?
The adjustable stroke is ideal for product changeovers on a line, whereas a fixed SAI cylinder is better for static, repetitive stops.
Because the 375 mm stroke is relatively long for a 32 mm bore, the 12 mm rod should be paired with an external guide to prevent excessive side-loading and rod deflection. To match this ISO 15552 replacement exactly, specify: 32 mm bore, 375 mm stroke, 50 mm adjustment, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet. For load-holding without live air, consider an external rod lock or the SAIL series instead.
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 SAIJ32BX375-50 FAQ
At 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the nominal 375 mm stroke by up to 50 mm, providing a usable travel range of 325 to 375 mm. It only sets the end position and does not lock the load.
