About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-10S
The AirTAC SAIJ32X115-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end position by up to 10 mm. This yields a usable travel window of 105 to 115 mm, providing precise end-position tuning at commissioning without swapping out the physical cylinder. It delivers a push force of 402 N at 0.5 MPa and reaches a maximum of 82 kgf at 1.0 MPa.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic solid-state switches. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-10S Is Used
Changeover Tuning
Dial in the 105-115 mm retract position during product size changeovers on a packaging line without swapping hardware.
End-Stop Calibration
Fine-tune the final end position during machine commissioning to absorb mechanical tolerance stacks accurately.
Variable Positioning
Adjust the travel window dynamically for assembly stations requiring slight positional shifts between batches.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-10S the Right Cylinder?
Choose this 32 mm bore when an application requires precise variable end-stops and a lower force output around 402 N at 0.5 MPa. If your process demands greater thrust, stepping up to the 40 mm bore increases the push force to 628 N at 0.5 MPa. The adjustable stroke is selected over a fixed SAI cylinder when you need machine setup flexibility or product changeover without adding external stops. The rear adjuster acts solely as a travel stop to set deceleration and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series. To match this ISO 15552 interchangeable cylinder, specify the 32 mm bore, 115 mm stroke, 10 mm adjustment, PT G1/8 port, and the -S magnet.

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 SAIJ32BX115-10S FAQ
It delivers a push force of 402 N and a pull force of 345 N at 0.5 MPa, reaching a maximum of 82 kgf at 1.0 MPa. The operational speed range for this 32 mm bore is 30-800 mm/s.
The rear adjuster screw allows you to shorten the nominal 115 mm stroke by up to 10 mm, creating a 105-115 mm usable travel window. The adjuster functions as a mechanical stop to tune the end position and does not lock the load without live air pressure.
