About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-50
The AirTAC SAIJ32X850-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel. With a nominal 850mm stroke and a 50mm adjustment range, it provides a usable travel window of 800 to 850mm for precise end-position tuning at commissioning.
This unit is configured with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, though this specific SKU is supplied without a magnet. The rear adjuster acts strictly as a travel stop to decelerate the piston, meaning it will not hold a load without continuous live air pressure.

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 SAIJ32AX850-50 Is Used
Variable End-Stop Tuning
Dial in the exact retract position from 800 to 850mm during machine commissioning to accommodate different product lengths without swapping cylinders.
Long-Stroke Diversion
Pushes items across a wide conveyor belt, using the rear adjuster to fine-tune the extension distance based on varying package widths.
Product Changeover Setup
Quickly adjust the travel end-point on automated assembly lines when switching between product variants, avoiding mechanical teardown.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-50 the Right Cylinder?
Selecting this 32mm bore cylinder makes sense when an application requires a long 850mm stroke but demands exact end-position calibration without adding external physical stops. Because the stroke is 850mm, the 12mm diameter rod is highly susceptible to side-loading and deflection; an external guide rail is strongly recommended to prevent premature seal wear and binding.
For direct ISO 15552 interchangeability, match the 32mm bore, 850mm stroke, 50mm adjustment range, PT port threads, and your required mounting bracket from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). If your machine requires true load-holding without live air, a standard SAIJ will not suffice; consider the SAIL air-released lock or BSAI clamp-lock series instead.
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 SAIJ32AX850-50 FAQ
At the maximum 1.0 MPa pressure, it achieves 82 kgf.
The rear adjuster screw allows you to shorten the 850mm nominal stroke by up to 50mm, giving an adjustable travel window of 800 to 850mm. This stopper fine-tunes the end position but does not lock or hold the load without live air pressure.
