About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-10S
The AirTAC SAIJ32X115-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 105-115 mm usable travel window, letting you trim the nominal 115 mm stroke by up to 10 mm during commissioning without adding external stops. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa operating pressure.
This unit includes a standard carbon steel rod and a -S magnet for position sensing. The extruded aluminum barrel features sensor grooves on both sides, accepting AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid supply is filtered air, and the standard PT tapered port thread ensures a tight pneumatic connection.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-10S Is Used
Machine Setup Tuning
Dial in the exact 105-115 mm end-stop during initial machine commissioning to perfect the pressing depth without swapping hardware.
Product Size Changeover
Quickly shorten the stroke by up to 10 mm on automated lines processing varying material thicknesses or package sizes.
Variable End-Stop Forming
Adjust the rear stopper screw to fine-tune the final resting position for light-duty forming or positioning tasks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-10S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when you need precise end-position tuning for product changeovers or varying material thicknesses, rather than installing a fixed-stroke SAI cylinder. If your application requires less force, stepping down is not an option in the SAIJ series, but if you need higher force, the 40 mm bore provides 628 N of push at 0.5 MPa. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For load-holding without pressure, consider an SAIL or BSAI cylinder.
To match this ISO 15552 interchangeable profile cylinder exactly, specify the 32 mm bore, 115 mm nominal stroke, 10 mm adjustment range, PT port thread, and the -S magnet option. The supported mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32X115-10S FAQ
The rear adjuster screw allows you to shorten the effective travel from the 115 mm nominal stroke down to 105 mm, giving a 105-115 mm usable window. It acts as a mechanical stop to decelerate the piston, but it is not a lock and will not hold the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ32X115-10-S provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
