About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX35-20S
The AirTAC SAIJ32X35-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you dial back the nominal 35 mm travel by up to 20 mm, creating a highly versatile 15-35 mm usable stroke window.
This adjustable design eliminates the need to physically swap cylinders or bolt on external stops during machine commissioning or product changeovers. It features a PT tapered port thread, integrated variable air cushions at both ends, and extruded aluminum barrel with sensor grooves on both sides for flexible CMSE or DMSE switch mounting.

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 SAIJ32BX35-20S Is Used
Machine Changeover
Dial in the exact end-stop position when switching between product sizes on a packaging line without changing the cylinder.
Gripping Setup
Fine-tune the retraction point during commissioning to prevent crushing delicate components in automated handling.
Sensor Integration
Leverage the magnetic piston and dual sensor grooves to mount CMSE or DMSE switches precisely along the travel path.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX35-20S the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning within a 15-35 mm travel window, rather than committing to a fixed-stroke SAI cylinder. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.
To match this ISO 15552 interchangeable cylinder for a replacement, verify the 32 mm bore, 35 mm base stroke, 20 mm adjustment range, PT port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR brackets.
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 SAIJ32BX35-20S FAQ
It operates at a speed range of 30-800 mm/s.
The rear adjuster screw allows you to shorten the 35 mm nominal stroke by up to 20 mm, giving a usable travel window of 15 to 35 mm. It acts as a mechanical stop and does not lock the load without live air pressure.
