About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-30
The AirTAC SAIJ32X190-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 160 to 190 mm, allowing you to trim the effective stroke by up to 30 mm without adding external stops. In its standard configuration, it delivers 402 N of push force at 0.5 MPa and uses a PT tapered G1/8 port.
This variant is built with an SUS420J2 stainless steel piston rod (code A) for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, and because no magnet is specified, position detection requires external sensors rather than internal CMSE or DMSE switches. The rear adjuster acts purely as a mechanical stop to set the end position, so it will not hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-30 Is Used
Product Changeovers
Dial in the stroke from 190 mm down to 160 mm to accommodate varying product sizes on the same line without changing the cylinder.
Commissioning Tuning
Fine-tune the exact retract end-position during machine setup to synchronize multiple actuators perfectly.
Machine Setup
Use the rear stopper to set precise mechanical limits during initial equipment assembly, ensuring repeatable travel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-30 the Right Cylinder?
Choose this 32 mm bore when your application requires precise end-position tuning at commissioning or during product changeovers, stepping up from smaller actuators or down from a 40 mm bore that yields 628 N at 0.5 MPa. An adjustable stroke is preferred over a fixed SAI cylinder when you need a variable end-stop but want to avoid physically swapping the actuator. For load-holding without live pressure, this cylinder is not a lock; you would need a SAIL or BSAI variant instead. Since the 190 mm stroke is below the 300 mm threshold, side-load risks are minimal, but the 12 mm rod and M10x1.25 thread still require standard alignment care. It is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32AX190-30 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N at 0.9 MPa.
The rear adjuster screw lets you shorten the nominal 190 mm stroke by up to 30 mm, creating a usable travel window of 160 to 190 mm. It functions as a mechanical stop, not a lock, meaning it cannot hold a load without live air pressure.
