About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-40
The AirTAC SAIJ32X100-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you trim the nominal 100 mm travel back by up to 40 mm. This yields a highly flexible 60-100 mm usable window, allowing precise end-position tuning at commissioning without bolting on external stops. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it suited for lighter-duty work.
Built with a SUS304 stainless steel rod (option B) and PT tapered ports, this 32 mm bore unit integrates variable air cushions at both ends to manage impact deceleration. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts purely as a travel stop to set the retract position; it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-40 Is Used
Machine Setup & Changeover
Dial in the exact retract position within the 60-100 mm window during product changeovers without swapping the entire cylinder.
Variable End Stops
Provides a mechanical hard stop for lighter-duty 402 N push applications where the exact end-of-stroke position varies between workpieces.
Light Material Handling
Sort or position light items on a conveyor line, using the rear screw to fine-tune the stopping distance for different package sizes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-40 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires variable end-stops or frequent product changeovers. If you need slightly higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa, whereas dropping to a smaller bore would sacrifice too much power. The SAIJ32X100-40 is selected over a fixed-stroke SAI when you need on-the-fly mechanical fine-tuning of the retract position during machine setup.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders. To match this exact configuration, specify a 32 mm bore, 100 mm nominal stroke, 40 mm adjustment range, PT ports, and SUS304 (B) rod material. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that neither the rear adjuster nor the air cushions function as a lock; for load-holding without live air, consider the SAIL or BSAI series.
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 SAIJ32BX100-40 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 of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 100 mm nominal stroke by up to 40 mm. This creates a usable travel window of 60-100 mm, which can be fine-tuned during commissioning without replacing the cylinder.
