About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX275-40S
The AirTAC SAIJ32X275-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability allows you to dial in the retract end position during commissioning without swapping out the cylinder or adding external stops.
This SKU includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and ships with a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and the rear adjuster acts purely as a travel stop, meaning it does not hold the load without live air pressure.

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 SAIJ32BX275-40S Is Used
Product Changeover
Quickly dial in the 235-275mm retract end-stop when switching between product sizes on a packaging line, avoiding mechanical rebuilds.
Machine Commissioning
Fine-tune the final resting position of tooling during setup, using the 40mm rear adjustment screw to perfect alignment without external shims.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX275-40S the Right Cylinder?
An adjustable stroke is favored over a fixed SAI cylinder when you need on-the-fly end-position tuning rather than a locked stroke. Because the 275mm stroke is relatively long for a 32mm bore, ensure you use an external guide to prevent excessive side-loading on the 12mm rod. The adjuster and air cushions only decelerate the travel end, so for load-holding without live pressure, look to the SAIL or BSAI series. To match this ISO 15552 interchangeable cylinder, specify: 32mm bore, 275mm stroke, 40mm adjustment, PT tapered port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and a -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 SAIJ32BX275-40S FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster allows you to shorten the 275mm nominal stroke by up to 40mm, providing a usable travel window of 235-275mm. The adjuster acts as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
