About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-75
The AirTAC SAIJ32X850-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end-of-travel position. With a nominal 850 mm stroke and a 75 mm adjustment range, it provides a usable travel window of 775 to 850 mm.
This unit is configured with a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic sensors if position feedback is needed later.

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 SAIJ32AX850-75 Is Used
Product Changeovers
Quickly adapt the stroke length from 775 to 850 mm during line changeovers to accommodate different product sizes without changing hardware.
End-Position Tuning
Fine-tune the retract end position during commissioning to achieve precise mechanical alignment without adding external stopper blocks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-75 the Right Cylinder?
The adjustable stroke is ideal for machine setup and product changeovers, letting you dial in the exact end position without swapping cylinders or adding external stops. At an 850 mm stroke, the 12 mm piston rod is highly susceptible to side-loading, so an external guide rail must be used to prevent binding.
For ISO 15552 interchangeability, match the 32 mm bore, 850 mm stroke, 75 mm adjustment, PT ports, and your required mounting option. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe holding, use an external rod lock or a SAIL cylinder.
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 SAIJ32AX850-75 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 75 mm. This creates an adjustable travel window from 775 mm to 850 mm, allowing you to set the exact retract position during installation without replacing the cylinder.
