About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-20S
The AirTAC SAIJ32X190-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. It provides a usable travel window of 170-190 mm, letting you dial back the nominal 190 mm stroke by up to 20 mm during commissioning without adding external stops. In the 32 mm bore class, it delivers 402 N of push force at 0.5 MPa and reaches speeds up to 800 mm/s.
This variant uses a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and includes a piston magnet (-S) for position sensing. You can mount AirTAC CMSE reed or DMSE electronic sensors directly into the extruded aluminum barrel grooves on both sides. The SAIJ mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-20S Is Used
Commissioning Fine-Tuning
Dial in the exact 170-190 mm end-position during machine setup to compensate for mechanical tolerance without swapping cylinders.
Product Changeover
Quickly adjust the retract stop by up to 20 mm on packaging lines when switching to a slightly different product size.
Variable End-Stop Assembly
Set precise retraction limits for light-duty assembly tasks requiring 402 N of push force and repeatable positioning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-20S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa and variable end-stops; if you need less force, dropping to a 20 mm bore reduces thrust, while stepping up to a 40 mm bore yields 628 N. The adjustable rear screw is a travel stop, not a lock, so it cannot hold a load without live air pressure. For fail-safe load holding, consider an external pilot-operated check valve or the AirTAC SAIL or BSAI cylinder series.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 190 mm stroke, 20 mm adjustment, PT tapered port thread, and the -S magnet requirement. Since this is a 190 mm stroke, side-load is minimal, but always verify rod alignment to prevent premature seal wear.
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 SAIJ32AX190-20S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 190 mm down to 170 mm. It only sets the travel end and deceleration point; it does not lock or hold the load without continuous air pressure.
At 0.5 MPa, it provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
