About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-20
The AirTAC SAIJ32X190-20 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 170-190 mm usable travel window, allowing you to dial back the 190 mm nominal stroke by up to 20 mm during commissioning. This bore size delivers 402 N of push force at 0.5 MPa, making it well-suited for lighter-duty tasks.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU lacks a magnet, adding one enables the use of AirTAC CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-20 Is Used
End-Position Tuning
Dial in the exact 170-190 mm travel distance during machine commissioning to perfect product placement without machining external stops.
Product Changeover
Quickly adjust the rear stopper by up to 20 mm to accommodate slight variations in incoming part sizes on a packaging line.
Light Assembly Tasks
Utilize the 402 N push force at 0.5 MPa for precise pressing or locating operations where the final position must be finely tuned.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-20 the Right Cylinder?
Select this 32 mm bore cylinder when an application requires precise end-position tuning without swapping hardware; if you need more force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The adjustable stroke is ideal for machine changeovers, whereas a fixed SAI cylinder is better for rigid, unvarying endpoints. Remember that the rear adjuster is a stop, not a lock—for load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
To match this exact ISO 15552 replacement, specify a 32 mm bore, 190 mm stroke, 20 mm adjustment range, PT tapered port threads, and no magnet. The 12 mm rod and M10x1.25 thread handle moderate side loads, but because the stroke is 190 mm, ensure adequate external guiding for the payload. Operating speed ranges from 30-800 mm/s.
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 SAIJ32AX190-20 FAQ
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 20 mm. This creates a usable travel window of 170-190 mm, which is set at commissioning without needing to change the cylinder.
At 0.5 MPa, this double-acting cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
