About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-75S
The AirTAC SAIJ32X550-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 550 mm stroke by up to 75 mm for a precise 475-550 mm usable travel window. Built with a SUS304 stainless steel rod and PT tapered ports, it generates 402 N of push force and 345 N of pull force at 0.5 MPa. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting of CMSE reed and DMSE electronic sensors.
Because the adjuster acts as a mechanical stop at the retract end, it enables fine end-position tuning during commissioning without swapping the cylinder or adding external stops. The rear stopper and the variable air cushions only decelerate the load; they do not hold the load without live air. For load-holding without pressure, consider an external rod lock or the related SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-75S Is Used
End-Stop Tuning
Dial in the exact retract position within the 475-550 mm window during machine commissioning without installing external physical stops.
Product Changeover
Quickly adjust the stroke end-position on packaging lines when switching to different product sizes or formats.
Fixture Positioning
Provides 402 N of push force at 0.5 MPa for clamping or positioning workpieces with a variable retract distance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-75S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa; step up to the 40 mm bore if you need 628 N. The adjustable-stroke design is ideal for machine setups requiring variable end-stops or product-size changeovers, unlike a fixed-stroke SAI cylinder. As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting interfaces using the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). To replicate this exact configuration, specify bore 32, stroke 550, adjustment 75, PT ports, SUS304 rod, and the -S magnet.
At 550 mm stroke, the 12 mm rod is highly susceptible to side loads. An external guide is recommended to prevent rod binding and premature seal wear over long unsupported travels.
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 SAIJ32BX550-75S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 75 mm, providing a usable travel window of 475 to 550 mm. It sets the end position but does not lock or hold the load without live air pressure.
At 0.5 MPa operating pressure, it delivers 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can generate up to 82 kgf of push force.
