About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-20
The AirTAC SAIJ32X230-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 210-230 mm usable travel window. It delivers 402 Newtons of push force at 0.5 MPa, making it well-suited for lighter-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This specific SKU uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The rear adjustment screw allows you to fine-tune the retract end position during commissioning without adding external stops. It features PT tapered port threads (G1/8) and operates at speeds between 30 and 800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-20 Is Used
Machine Setup Changeover
Dial in the exact 210 to 230 mm retract position during product size changes without swapping out the entire cylinder or adding external stopper blocks.
Light Assembly Positioning
Leverage the 402N push force at 0.5 MPa to move small parts into place, using the rear screw to fine-tune the final end-of-stroke location accurately.
Variable End-Stop Diverter
Adjust the stroke length on the fly for conveyor diverting tasks where the physical contact point needs slight variation based on package dimensions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-20 the Right Cylinder?
Choose this 32 mm bore if you need precise end-position tuning for product changeovers, stepping up from smaller actuators or down from a 40 mm bore that provides 628N push force at 0.5 MPa. The adjustable rear stopper is ideal for dialing in exact travel distances, whereas a fixed SAI cylinder locks you into a single 230 mm stroke.
When integrating this actuator, remember the rear adjuster acts only as a travel stop and does not hold the load without live air pressure. For position-holding requirements without continuous air, consider an SAIL pneumatic lock or BSAI clamp-lock cylinder. This unit uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets.
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 SAIJ32AX230-20 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 Newtons of push force and 345 Newtons of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the nominal 230 mm stroke by up to 20 mm, creating a usable travel window of 210 to 230 mm. This stopper decelerates the travel end but does not lock the load without live air pressure.
