About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-20
The AirTAC SAIJ32X115-20 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 95-115mm usable travel window, allowing you to dial back the nominal 115mm stroke by up to 20mm during commissioning.
This model features a SUS304 stainless steel piston rod for superior corrosion resistance and uses PT tapered port threads (G1/8). The extruded aluminum barrel includes sensor grooves on both sides. However, since no magnet is specified, position sensing via CMSE reed or DMSE electronic switches is not enabled on this specific configuration.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ32BX115-20 Is Used
Machine Changeover
Quickly adjust the 95-115mm travel window to accommodate slight variations in product dimensions without swapping the cylinder.
End-Position Tuning
Fine-tune the exact retraction point during initial commissioning to prevent mechanical interference and optimize cycle timing.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-20 the Right Cylinder?
Choose this 32mm bore when you need exact end-stop tuning without adding external physical stops to your machine. If your application requires less force, stepping down is not an option below 32mm in this series, but if you need significantly more thrust, a 40mm bore provides 628N at 0.5MPa. The adjustable rear screw is strictly a travel stop, not a locking mechanism; it cannot hold a load without live air pressure, so consider an SAIL or BSAI cylinder if load-holding is required.
Because this is a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders. To match this unit exactly, specify a 32mm bore, 115mm stroke, 20mm adjustment range, PT ports, SUS304 rod, and no magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR mounts.
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 SAIJ32BX115-20 FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 115mm down to 95mm. This provides a 20mm tuning window to set the exact retraction end-position without changing the cylinder.
