About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX145-20S
The AirTAC SAIJ32X145-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 125 to 145 mm usable travel window, allowing you to dial back the 145 mm nominal stroke by up to 20 mm during commissioning.
This SKU ships with a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and includes a piston magnet for CMSE reed or DMSE electronic sensors. The extruded aluminum barrel retains standard ISO 15552 mounting dimensions, ensuring strict dimensional interchangeability without adopting a tie-rod construction.

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 SAIJ32AX145-20S Is Used
Machine Changeover
Dial in the 125-145 mm travel window during product size changes to set new end stops without machining new hard stops.
Component Seating
Fine-tune the final 20 mm of retraction to softly seat delicate electronic components against a fixed backstop.
Diversion Gates
Adjust the stroke on pneumatic sorting gates to accommodate varying package widths on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX145-20S the Right Cylinder?
If your application requires less force, step down to the 20 mm bore (pushing 128 N at 0.5 MPa); for heavier loads, step up to the 40 mm bore (628 N). The rear adjuster acts purely as a mechanical stop to set deceleration and travel ends, meaning it will not hold a load without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series. To match this cylinder for an ISO 15552 replacement, verify the 145 mm stroke, the 20 mm adjustment range, PT tapered port threads, and the -S magnet option.
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 SAIJ32AX145-20S FAQ
It operates at speeds ranging from 30 to 800 mm/s.
A rear adjusting screw lets you mechanically shorten the effective stroke from 145 mm down to a minimum of 125 mm. This stopper only sets the travel end and deceleration; it does not lock the load without continuous air pressure.
