About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-100S
The AirTAC SAIJ32X100-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 100 mm travel to anywhere in a 0-100 mm usable window. Delivering 402 N of push force at 0.5 MPa, it is designed for applications requiring exact end-position tuning without swapping hardware.
This variant includes a magnet for CMSE reed and DMSE electronic sensors, utilizing the dual sensor grooves machined into the extruded aluminum barrel. It features a 12 mm carbon steel rod with an M10x1.25 thread, and uses a PT tapered G1/8 port. The SAIJ mounting set omits FB, CA, CB, and CR options, supporting Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-100S Is Used
Variable End-Stop Tuning
Dial in the exact retract position from 0 to 100 mm during commissioning to accommodate varying product sizes without adding external stopper blocks.
Machine Changeover
Rapidly adjust the effective stroke on packaging lines when switching between different package lengths, minimizing downtime.
Assembly Positioning
Use the 402 N push force to press or position light components, relying on the rear screw to set precise final coordinates.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-100S the Right Cylinder?
Choose this 32 mm bore when you need precise 0-100 mm travel flexibility and up to 402 N of thrust at 0.5 MPa. If your application requires greater force, stepping up to the 40 mm bore yields 628 N of push force. The rear adjuster screw acts purely as a mechanical stop to fine-tune the retract end; it does not lock the load. For true fail-safe load holding without live air pressure, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 100 mm nominal stroke, 100 mm adjustment range, PT G1/8 port, and the -S magnet requirement. Because the stroke is 100 mm, side loads are minimal, but always ensure the M10x1.25 rod thread is aligned to prevent binding during the adjustable travel window.
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 SAIJ32X100-100S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw allows you to mechanically shorten the effective travel from 100 mm down to 0 mm, creating a 0-100 mm usable window. This stopper only sets the end position and does not lock the load without live air.
