About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X110-50S
The AirTAC SAIJ32X110-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the 110 mm nominal travel by up to 50 mm, creating a highly flexible 60-110 mm usable window. Delivering 402 N of push force and 345 N of pull force at 0.5 MPa, it fits perfectly into compact pneumatic setups requiring precise end-position tuning without external stops. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for use with CMSE reed and DMSE electronic sensors.
This model uses a 12 mm carbon steel rod with an M10x1.25 thread and a G1/8 port. 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. For applications requiring true load-holding without continuous pressure, consider the SAIL or BSAI series instead. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X110-50S Is Used
Product Changeover
Dial in the exact 60 to 110 mm end-position on the fly when switching between different package sizes on a packaging line.
Machine Setup
Fine-tune the retract stop during commissioning without machining new spacer blocks or swapping out the entire cylinder.
Variable End Stops
Use the rear adjuster to test multiple stroke lengths during prototyping, finding the optimal travel before finalizing the design.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X110-50S the Right Cylinder?
Choose this 32 mm bore if your application requires up to 402 N of thrust at 0.5 MPa and benefits from a variable end-stop during commissioning or product changeover. If your setup demands higher force, stepping up to the 40 mm bore yields 628 N of push force at the same pressure. The adjustable 60-110 mm travel window is ideal for prototyping or machines running multiple product sizes, replacing the need to stock several fixed-stroke SAI cylinders. Because the stroke is 110 mm, side-loading is less severe than on longer strokes, but you should still ensure proper guiding for any lateral loads.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 110 mm nominal stroke, 50 mm adjustment range, PT tapered port thread, and the -S magnet requirement. The SAIJ series omits FB, CA, CB, and CR mounts, so verify your mounting interface against the available Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. The standard variable air cushions at both ends help decelerate the moving load within the 30-800 mm/s speed range.

- ✓ 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 SAIJ32X110-50S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers 82 kgf.
The rear adjuster screw allows you to shorten the 110 mm nominal stroke by up to 50 mm, providing a usable travel window of 60 to 110 mm. The adjuster acts as a mechanical stop and does not lock the load without live air pressure.
