About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-40S
The AirTAC SAIJ32X290-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability eliminates the need to swap cylinders or bolt on external stops when fine-tuning end positions.
This SKU includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and PT tapered port threads. The -S magnet enables position sensing with CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for load-holding without pressure, consider an external rod lock or the SAIL series.

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 SAIJ32BX290-40S Is Used
Product Changeovers
Quickly adjust the 250-290mm travel window to accommodate different product lengths on the same packaging line without changing hardware.
Machine Commissioning
Fine-tune the retract end-position during setup to achieve precise alignment, avoiding the cost of custom-length cylinders.
Variable End Stops
Dial in the exact stopping point for delicate operations, using the rear screw to set the exact 40mm trim range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-40S the Right Cylinder?
If your application requires less force, stepping down is not an option below 32mm in this series, but stepping up to a 40mm bore yields 628N. The adjustable stroke is ideal for machines running multiple product sizes, whereas a fixed SAI cylinder suits single-purpose tasks. To replace an ISO 15552 cylinder, match the 32mm bore, 290mm stroke, 40mm adjustment, PT port, and -S magnet.
Because the 290mm stroke is relatively long for a 32mm bore, the 12mm rod and M10x1.25 thread still require external guidance to prevent excessive side-loading. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ32BX290-40S FAQ
At 0.7 MPa, the push force increases to 563N.
The rear adjuster screw allows you to shorten the effective stroke from 290mm down to 250mm. It acts as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
