About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-20S
The AirTAC SAIJ32X105-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 85 to 105 mm, allowing you to dial back the nominal 105 mm stroke by up to 20 mm during commissioning.
This model includes a magnetic piston for position detection, working seamlessly with AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side sensor grooves. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions while the rear adjuster acts purely as a travel stop to set end positions without requiring external stops.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-20S Is Used
Machine Changeover
Quickly fine-tune the 85-105 mm travel window during product size changes without swapping cylinders or adding external mechanical stops.
End-Position Tuning
Dial in the exact retract distance by up to 20 mm at commissioning to perfect the picking or pushing position of delicate components.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-20S the Right Cylinder?
The 20 mm adjustment range is ideal for product changeovers where the exact end-of-stroke varies slightly, avoiding the need to physically swap out a fixed-stroke SAI cylinder.
For replacement, match the 32 mm bore, 105 mm nominal stroke, 20 mm adjuster, PT tapered G1/8 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Remember that the rear adjuster is a stop, not a lock; it will not hold a load without live air pressure, so consider an SAIL or BSAI cylinder if fail-safe holding is required.
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 SAIJ32BX105-20S FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke by up to 20 mm. This creates a usable travel window of 85 to 105 mm so you can fine-tune the end position without replacing the cylinder.
It operates at speeds between 30 and 800 mm/s.
