About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-75
The AirTAC SAIJ32X75-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 75 mm nominal stroke that can be dialed back by up to 75 mm, yielding a highly versatile 0 to 75 mm usable travel window for exact end-position tuning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty handling tasks.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The rear adjuster acts purely as a travel stop to fine-tune the retract position without adding external stops, while the dual air cushions manage end-of-stroke deceleration. It supports AirTAC CMSE reed and DMSE electronic sensors via the dual-side barrel grooves when a magnet is specified.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-75 Is Used
Prototype Positioning
Dial in the exact retract stop during R&D or machine commissioning without machining new hard stops.
Product Changeover
Quickly adjust the 0-75 mm travel window on packaging lines when switching to different package lengths.
Corrosive Testing
The SUS304 stainless steel rod performs reliably in light chemical or moisture-heavy laboratory environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-75 the Right Cylinder?
Choose this 32 mm bore when your application requires a maximum 402 N push force at 0.5 MPa; step up to the 40 mm bore if you need 628 N. The massive 75 mm adjustment range on this 75 mm stroke allows you to completely null the travel or set any intermediate stop point, which is ideal for prototyping or machines handling varying product sizes. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as this adjuster is only a stop.
For dimensionally interchangeable ISO 15552 replacements, match the 32 mm bore, 75 mm stroke, 75 mm adjustment range, PT port threads, SUS304 rod, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is under 300 mm, side-load concerns are minimal, but always ensure the M10x1.25 rod thread is aligned to prevent binding.
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 SAIJ32BX75-75 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to trim the effective stroke anywhere from 0 to 75 mm. It sets the end position but does not lock the load without live air pressure.
