About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX20-10
The AirTAC SAIJ32X20-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 10-20 mm window. It delivers 402N of push force at 0.5 MPa, making it well-suited for compact, lower-force automation tasks. The piston rod is constructed from SUS420J2 stainless steel, offering a durable surface for general industrial environments.
This model features PT tapered port threads (G1/8) and variable air cushions at both ends to manage end-of-stroke impacts. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches if needed later. It supports a standard operating speed range of 30-800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX20-10 Is Used
Stroke Calibration
Dial in the exact 10-20mm travel distance during machine commissioning to achieve precise end-positioning without adding external stops.
Product Changeover
Quickly adjust the rear stopper to accommodate slight variations in part sizes on a production line, minimizing downtime.
Compact Assembly
Utilize the 32mm bore's 402N force for light-duty clamping or positioning tasks where space is restricted and exact travel is critical.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX20-10 the Right Cylinder?
Choose this 32mm bore when your application requires less force than a 40mm bore (which provides 628N push at 0.5 MPa) but still needs precise positioning. The 10mm rear adjustment screw is ideal for dialing in exact end-stops during machine commissioning or product changeovers without physically swapping the cylinder. For mounting, this SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, omitting the FB, CA, CB, and CR options. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider an external rod lock or the SAIL/BSAI series.
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 SAIJ32AX20-10 FAQ
At a 0.5 MPa operating pressure, the 32mm bore generates 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the nominal 20mm stroke by up to 10mm, providing a usable travel window of 10-20mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
