About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX120-20S
The AirTAC SAIJ32X120-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 100-120 mm, allowing you to dial back the 120 mm nominal stroke by up to 20 mm during machine setup. In the compact 32 mm bore class, it delivers 402 N of push force at 0.5 MPa and 724 N at 0.9 MPa.
This SKU is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet (-S) for position sensing. It is compatible with AirTAC CMSE reed and DMSE electronic sensors fitted into the dual-side sensor grooves on the extruded aluminum barrel. The PT tapered port threads match the G1/8 air supply, and the integrated air cushions decelerate the load at both ends.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX120-20S Is Used
Machine Changeover
Dial in the exact 100-120 mm end-stop during product size changes without physically swapping cylinders or repositioning hard stops.
Clamping Force Tuning
Fine-tune the clamping reach on assembly lines to accommodate varying part tolerances using the rear adjustment screw.
Sensor Positioning
Utilize the integrated magnet and dual sensor grooves to track the piston across its adjusted travel window.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX120-20S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires precise end-position tuning at commissioning without swapping out the physical cylinder or adding external stops. If you need higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For true load-holding, consider the SAIL or BSAI series.
To replace an ISO 15552 cylinder, match the 32 mm bore, 120 mm stroke, 20 mm adjustment range, G1/8 PT port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 120 mm stroke is relatively short, the 12 mm rod handles side loads well, though long unsupported strokes still need an external guide.
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 SAIJ32BX120-20S 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 0.9 MPa, the push force increases to 724 N. The standard operating speed range is 30-800 mm/s.
The rear adjusting screw acts as an external stopper that lets you shorten the effective stroke by up to 20 mm. This creates a usable travel window of 100-120 mm, allowing precise end-position tuning at commissioning without replacing the cylinder.
