About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-20S
The AirTAC SAIJ32X950-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 930 to 950 mm, enabling precise end-position tuning without external stops.
This model includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides. Because the 950 mm stroke is long, the 12 mm rod requires an external guide to prevent excessive side-loading and deflection.

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 SAIJ32BX950-20S Is Used
Machine Setup Changeover
Dial in the 930-950 mm travel window during product line changeovers to accommodate varying part sizes without physically replacing the cylinder.
Extended Transfer Positioning
Precisely tune the end stop on a long-stroke material transfer conveyor, using the rear screw to correct for minor mechanical drift over time.
Assembly Station Calibration
Fine-tune the retract stroke at an assembly station during commissioning, ensuring perfect alignment before the SUS304 rod engages the tooling.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-20S the Right Cylinder?
If your application requires higher thrust, stepping up to the 40 mm bore yields 628 N. The 20 mm rear adjuster allows you to fine-tune the retract position during commissioning or product changeover, which is far more efficient than swapping a fixed-stroke SAI cylinder.
For ISO 15552 mounting-interface replacements, match the 32 mm bore, 950 mm stroke, 20 mm adjustment, PT port, and -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 travel stop, not a lock; it will not hold a load without live air. For load-holding, consider SAIL or BSAI cylinders.

- ✓ 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 SAIJ32BX950-20S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 20 mm. This creates a usable travel window of 930 to 950 mm, allowing precise end-position tuning without changing the cylinder. It is a travel stop, not a lock, so it cannot hold a load without live air pressure.
At the maximum 1.0 MPa pressure, it delivers up to 82 kgf. The 12 mm SUS304 stainless steel rod handles the thrust while offering corrosion resistance.
