About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-40S
The AirTAC SAIJ32X750-40-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 710 to 750 mm, allowing you to fine-tune the retract end-position by up to 40 mm during commissioning without adding external stops.
This 32 mm bore model uses a PT tapered G1/8 port and achieves speeds of 30-800 mm/s. The extruded aluminum barrel incorporates sensor grooves on both sides, and the mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster functions strictly as a travel stop for deceleration, not a load-holding lock.

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 SAIJ32AX750-40S Is Used
Machine Changeover
Dial in the 710-750 mm travel window during product-size changeovers without physically swapping the cylinder or reworking external stop hardware.
End-Position Tuning
Use the 40 mm rear adjuster to fine-tune the retract stroke at commissioning, compensating for mechanical tolerance stack-ups.
Diversion Gates
Actuate conveyor routing gates where the exact end-stop position varies slightly by package size, using the integrated magnet for DMSE sensor feedback.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-40S the Right Cylinder?
An adjustable stroke is selected over a fixed SAI when a machine requires variable end-stops or product-size changeovers. To replace an ISO 15552 cylinder, match the 32 mm bore, 750 mm stroke, PT G1/8 port, and the -S magnet. Because the 750 mm stroke is long, an external guide is recommended to manage side-load and prevent rod bending.
For applications needing to hold a load without live air pressure, note that the SAIJ rear adjuster and air cushions do not function as a lock. You must use an external pilot-operated check valve or select an AirTAC SAIL or BSAI series cylinder for secure load-holding.
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 SAIJ32AX750-40S FAQ
At the maximum 1.0 MPa pressure, it reaches 82 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 40 mm, providing a usable travel window of 710 to 750 mm. It only sets the end position and does not lock the load.
