About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-20S
The AirTAC SAIJ32X105-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 105 mm stroke that can be fine-tuned down by up to 20 mm, creating an exact 85-105 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit is built for precision end-position tuning without swapping hardware.
This variant includes a magnet for CMSE reed and DMSE electronic sensors, utilizing the dual sensor grooves on its extruded aluminum barrel. It features a carbon steel rod and PT tapered port threads. The rear adjuster acts purely as a mechanical stop to set the retract end position, meaning it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-20S Is Used
End-Position Tuning
Dial in the exact retract distance within the 85-105 mm window during machine commissioning to perfect part seating.
Product Changeover
Quickly adjust the stroke by up to 20 mm on the rear stopper when running a new product size on the line.
Light Assembly Push
Utilize the 402 N push force at 0.5 MPa for precise light-duty pressing and indexing tasks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-20S the Right Cylinder?
Select this 32 mm bore cylinder when an application requires 402 N push force at 0.5 MPa but demands variable end-stops for product changeovers. If your setup needs less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N. The adjustable stroke is chosen over a fixed SAI cylinder to allow commissioning tweaks without adding external stops. For load-holding without air pressure, use a SAIL or BSAI cylinder instead.
Because the stroke is 105 mm, side-load risks are minimal, but always ensure the 12 mm carbon steel rod is properly guided. This SAIJ32X105-20-S is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2.
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 SAIJ32X105-20S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the 105 mm nominal stroke by up to 20 mm, providing an adjustable travel window of 85 to 105 mm. The adjuster is a mechanical stop, not a lock, and cannot hold a load without continuous air pressure.
