About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-75
The AirTAC SAIJ32X180-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from 180 mm to a minimum of 105 mm. This 75 mm adjustment window is ideal for dialing in exact end positions during machine commissioning or product changeovers without adding external stops. Built with a SUS304 stainless steel rod and a PT tapered port thread, it delivers 402 N of push force at 0.5 MPa.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the rear adjuster acts purely as a travel stop to set deceleration and end limits; it does not hold the load without live air pressure. For applications requiring true position holding, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-75 Is Used
Machine Commissioning
Dial in the exact retract end-position within the 105-180 mm window during initial setup without swapping out the entire cylinder.
Product Changeover
Quickly adjust the stroke length on packaging lines when handling different product sizes, using the 75 mm rear stopper range.
Variable End Stops
Set precise travel limits for light-duty assembly tasks, relying on the 402 N push force to move small jigs and fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-75 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires a 105-180 mm stroke range and moderate force (402 N push at 0.5 MPa). If you need higher thrust, stepping up to the 40 mm bore increases the push force to 628 N at 0.5 MPa. The adjustable rear stopper is favored over a fixed-stroke SAI cylinder when you need variable end-stops or precise end-position tuning at setup. To match this ISO 15552 replacement exactly, verify the 180 mm stroke, 75 mm adjustment, PT port, and the SUS304 rod material. Since this model lacks the -S magnet option, it will not work with CMSE or DMSE sensors without modification.
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 SAIJ32BX180-75 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 the maximum pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster screw lets you shorten the 180 mm nominal stroke by up to 75 mm, creating a usable travel window of 105-180 mm. The adjuster functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
