About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-75
The AirTAC SAIJ32X800-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 725 to 800 mm window. Delivering 402 N of push force at 0.5 MPa, it utilizes a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and a PT tapered port thread for a secure pneumatic seal.
Because the adjuster acts purely as a mechanical stop at the retract end, it does not hold the load without live air; for position holding, consider an external rod lock or the SAIL series. This 32 mm bore model operates at speeds of 30-800 mm/s and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-75 Is Used
End-Position Tuning
Dial in the exact retract distance within the 725-800 mm window during commissioning to perfect product placement without external stopper blocks.
Line Changeover
Quickly adjust the stroke by up to 75 mm when switching between different product sizes on a packaging or sorting conveyor.
Machine Setup
Use the rear mechanical stopper to safely set the precise travel limit during initial machinery assembly and testing.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-75 the Right Cylinder?
Choose this 32 mm bore cylinder when you need 402 N push force at 0.5 MPa combined with on-machine travel adjustment. If your application requires less force, stepping down is not an option below 32 mm in this range, but stepping up to a 40 mm bore provides 628 N of push force at 0.5 MPa. The adjustable stroke is ideal for product changeovers, allowing you to shift the end position by up to 75 mm without swapping the cylinder or adding external stops.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 800 mm stroke, PT port thread, and the chosen mounting style. Since this unit features an 800 mm stroke, the 12 mm diameter rod and M10x1.25 rod thread will experience amplified side loads if the load is unsupported; always guide the load externally to prevent binding. Note that this configuration lacks a magnet, so CMSE or DMSE sensors cannot be used without specifying the -S option.
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 SAIJ32AX800-75 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 800 mm stroke by up to 75 mm, giving an effective travel window of 725 to 800 mm. It is a stop, not a lock, and cannot hold the load without continuous air pressure.
