Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-100S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 100mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-100S
The AirTAC SAIJ32X100-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 12mm SUS304 stainless steel rod. Because this specific SKU carries a -100 adjustment code on a 100mm nominal stroke, you gain a massive 0-100mm usable travel window, letting you dial the exact end position down to zero without swapping the unit.
This model includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting. It uses PT tapered ports sized G1/8, and the rear adjuster acts purely as a mechanical stop to set the travel end—it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-100S Is Used
Machine Changeovers
Dial in the 0-100mm travel window during product size changeovers to set new retract end positions without adding external stops.
Prototype Positioning
Perfect for R&D setups where the exact end-of-stroke location is unknown, allowing live fine-tuning of the 12mm SUS304 rod extension.
Sensor Testing Rigs
The integrated magnet works seamlessly with DMSE electronic sensors for precise position feedback in adjustable travel test fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-100S the Right Cylinder?
Choose this 32mm bore when you need precise positioning over a short distance, as stepping down is not an option and stepping up to a 40mm bore yields 628N at 0.5 MPa. The 100mm adjustment range is ideal for prototyping or product changeovers where the final travel distance is unknown until commissioning. Unlike a fixed-stroke SAI cylinder, this adjustable version lets you fine-tune the retract end position on the fly.
When replacing an ISO 15552 cylinder, match the 32mm bore, 100mm nominal stroke, G1/8 PT ports, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without continuous air pressure, use an external rod lock or pilot-operated check valve, or look at the SAIL or BSAI series.

- ✓ 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 SAIJ32BX100-100S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach up to 724N push force at 0.9 MPa.
The rear adjuster screw lets you shorten the effective travel from 100mm down to 0mm. It acts as a mechanical stop to set the end position, but it does not lock or hold the load without live air pressure.
