About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-20
The AirTAC SAIJ32X275-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 255 to 275 mm, allowing you to dial back the nominal 275 mm stroke by up to 20 mm during machine commissioning.
This variant uses a SUS420J2 stainless steel rod for superior corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE solid-state switches if a magnet is specified later. It features PT tapered port threads (G1/8) and adjustable air cushions at both ends to decelerate the load smoothly.

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 SAIJ32AX275-20 Is Used
Machine Changeover
Dial in the exact retract distance up to 20 mm when switching between product sizes on a packaging line, avoiding the need to physically swap cylinders.
End-Position Tuning
Fine-tune the final end-stop during initial commissioning to compensate for mechanical tolerances without adding bulky external stopper blocks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-20 the Right Cylinder?
The adjustable stroke is selected over a fixed SAI cylinder when product sizes change on a line, letting you fine-tune the retract end-position without swapping hardware. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. To match this ISO 15552 replacement, specify the 32 mm bore, 275 mm stroke, 20 mm adjustment, PT G1/8 port, and no magnet. For a 275 mm stroke, ensure external guides support the rod to prevent excessive side-loading.
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 SAIJ32AX275-20 FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 20 mm, providing a usable travel window of 255 to 275 mm. The adjuster acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
The double-acting cylinder operates at speeds between 30 and 800 mm/s, supported by adjustable air cushions at both ends.
