About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX120-10S
The AirTAC SAIJ32X120-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. It provides a usable travel window of 110-120 mm, letting you shorten the effective stroke by up to 10 mm without adding external stops. This 32 mm bore unit delivers a 0.5 MPa push force of 402 N and a pull force of 345 N.
Built with a SUS304 stainless steel rod (option B), it is equipped with a magnet for position sensing via CMSE reed or DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It uses PT tapered ports and relies on variable air cushions at both ends to decelerate the load.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX120-10S Is Used
End-Position Tuning
Dial in the exact retract distance within the 110-120 mm window during machine commissioning without swapping hardware.
Product Changeover
Adjust the travel stop on the fly to accommodate slightly different product sizes on the same line.
Sensor Integration
Utilize the built-in magnet with CMSE or DMSE switches to confirm the adjusted end position in automated setups.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX120-10S the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning during commissioning or product changeover, avoiding the need to swap a fixed-stroke SAI cylinder. If your application requires higher force, stepping up to the 40 mm bore yields a 628 N push force at 0.5 MPa. The 12 mm rod and M10x1.25 thread handle moderate side loads, but for long unsupported strokes over 300 mm, an external guide is recommended. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. This model is dimensionally interchangeable per ISO 15552, configured with PT ports, the specified mounting, and a -S magnet.
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 SAIJ32BX120-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides a push force of 402 N and a pull force of 345 N. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw lets you shorten the nominal 120 mm stroke by up to 10 mm, creating a usable travel window of 110-120 mm. This stopper only sets the travel end and does not lock the load without live air pressure.
