About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-75
The AirTAC SAIJ32X105-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 402N of push force at 0.5MPa and provides a highly flexible usable travel window from 30 to 105mm. This wide adjustment range allows operators to dial in the exact retract end-position during commissioning without swapping hardware.
Equipped with a SUS304 stainless steel rod and PT tapered ports, this 32mm bore unit runs at speeds of 30-800mm/s. It utilizes variable air cushions at both ends to decelerate the load. The rear adjuster functions strictly as a travel stop for position tuning, not as a locking device, meaning live air pressure is required to hold the load.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-75 Is Used
Product Changeovers
Quickly reconfigure the retract distance from 30 to 105mm on packaging lines handling varying container sizes without changing the cylinder.
End-Position Tuning
Fine-tune the exact stopping point during machine commissioning to achieve perfect alignment without adding external mechanical stops.
Adjustable Ejection
Dial in the precise ejection stroke for delicate parts, using the 75mm adjustment window to prevent overtravel and damage.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-75 the Right Cylinder?
Choose this 32mm bore model when an application requires precise end-position tuning over a wide 75mm window. If your setup needs less than 30mm of total travel, stepping down to a shorter base stroke is advised. Conversely, if your thrust requirements exceed the 402N push force at 0.5MPa, stepping up to the 40mm bore yields 628N. The adjustable rear stop is ideal for product changeovers on a line, replacing the need to physically bolt on external stops or buy a fixed-stroke SAI cylinder.
When matching ISO 15552 replacements, confirm the 105mm nominal stroke, 75mm adjuster code, PT port thread, and SUS304 (code B) rod material. Because this cylinder lacks a magnet, position sensing requires external switches. For applications that must hold a load without continuous air pressure, consider the SAIL or BSAI locking cylinder series instead of relying on the stop screw.
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 SAIJ32BX105-75 FAQ
At 0.5MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7MPa, the push force increases to 563N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from its 105mm nominal length down to 30mm. It sets the travel end but does not lock the load without air pressure.
