About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-10S
The AirTAC SAIJ32X135-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 125 to 135 mm. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and features an integrated magnet for position sensing. The extruded aluminum barrel includes sensor grooves on both sides, accommodating AirTAC CMSE reed and DMSE electronic switches without extra brackets.
This adjustable-stroke model allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. The rear screw acts strictly as a travel stop to set the retract position, not a load-holding lock. Fluid must be filtered to 40 um, and the PT tapered port threads match standard 32 mm bore G1/8 connections.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-10S Is Used
Machine Setup Fine-Tuning
Dial in the exact 125 to 135 mm end-position during commissioning to perfect component seating without machining new hard stops.
Product Size Changeover
Quickly adjust the retract distance on packaging lines when running different product lengths, saving changeover time.
Variable End-Stop Assembly
Use the 10 mm trim window to precisely control the pressing depth of lightweight 32 mm bore assembly operations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-10S the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires 402 N of push force at 0.5 MPa with a variable end-stop. If your setup demands less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N. The 10 mm adjustment range is ideal for fine-tuning machine setup or product changeover, whereas a fixed SAI cylinder locks you into a single 135 mm dimension. For load-holding without live air pressure, consider an external rod lock or the AirTAC SAIL lock cylinder, as the SAIJ adjuster cannot hold a load.
Because the 135 mm stroke exceeds 100 mm, ensure adequate guidance for the 12 mm diameter rod to prevent excessive side-loading. This SAIJ32X135-10-S is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ32BX135-10S 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 the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a 125 to 135 mm usable travel window. It functions as a mechanical stop to set the end position and is not a lock.
