About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX60-30
The AirTAC SAIJ40X60-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 30 to 60 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides, allowing direct mounting of CMSE reed or DMSE electronic switches if a magnet is added later.
This adjustable-stop design enables precise end-position tuning at commissioning without swapping hardware. The rear adjuster acts purely as a travel stop to set deceleration limits, meaning it will not hold a load without live air pressure. It supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 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 SAIJ40 Adjustable Cylinder SAIJ40BX60-30 Is Used
Machine Setup Tuning
Dial in the exact 30 to 60mm end-position during commissioning to perfect a pressing operation without machining custom spacers.
Product Changeover
Quickly shorten the cylinder reach by up to 30mm on a packaging line to accommodate different carton sizes on the fly.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX60-30 the Right Cylinder?
An adjustable stroke is selected over a fixed SAI when a machine requires variable end-stops for rapid product changeover. To replace an ISO 15552 cylinder, match the 40mm bore, 60mm nominal stroke, 30mm adjustment, PT port thread, and the specific mounting accessory.
Because the stroke is under 300mm, side-load risks are minimal, but the 16mm rod and M12x1.25 thread still require standard alignment to prevent seal wear. For applications needing true load-holding without live pressure, select the SAIL or BSAI series instead, as the SAIJ rear stop is not a locking mechanism.
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 SAIJ40 Adjustable Cylinder SAIJ40BX60-30 FAQ
The rear adjuster screw allows you to trim the effective travel back by up to 30mm, creating a usable stroke window of 30 to 60mm. It acts as a physical stop to set the end position and does not lock the load without air pressure.
