About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-50
The AirTAC SAIJ32X100-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the nominal 100mm travel back by up to 50mm. This creates a highly flexible 50-100mm usable stroke window, letting you dial in the exact retract end-position during commissioning without swapping out the barrel or adding external stops. It delivers 402N of push force and 345N of pull force at 0.5 MPa, making it well-suited for compact automation tasks.
This variant is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-50 Is Used
Machine Changeover
Quickly adapt retract depth during product size changeovers using the 50mm adjustment window, eliminating the need to physically swap cylinders on the line.
End-Stop Fine Tuning
Dial in the exact 50-100mm stroke requirement during commissioning to perfect positioning without relying on external mechanical stops.
Compact Assembly
Leverage the 32mm bore and 402N push force for light-duty clamping and lifting tasks where a standard fixed stroke would be too rigid.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-50 the Right Cylinder?
Choose this 32mm bore adjustable cylinder when your machine setup requires variable end stops or frequent product changeovers, as the 50mm adjustment range provides exceptional flexibility for a compact frame. If your application demands higher thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa, but if you need precise position tuning in a tight footprint, this model is ideal. Because the stroke is 100mm, side-loading is minimal, though the 12mm rod and M10x1.25 thread still require standard alignment.
When replacing an ISO 15552 cylinder, match the 32mm bore, 100mm nominal stroke, 50mm adjustment requirement, PT G1/8 port, and your preferred mounting attachment. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR brackets. Since this unit lacks a magnet (-S), it will not directly support Hall effect or reed sensors without modification.

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 SAIJ32BX100-50 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can deliver up to 724N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 100mm stroke by up to 50mm, providing a usable stroke window of 50-100mm. The adjuster acts as a mechanical stop and does not lock the load without continuous air pressure.
