About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-75
The AirTAC SAIJ32X100-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 100 mm travel back by up to 75 mm, creating a wide 25-100 mm usable window. This is ideal for machines requiring highly variable end-stops without swapping hardware. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, utilizing a G1/8 port and a 12 mm carbon steel rod.
Unlike a fixed-stroke SAI, this model lets you dial in the exact end position during commissioning. The rear screw acts purely as a mechanical stop to set the retract position, meaning it will not hold the load if air pressure drops. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch mounting.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-75 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 25 and 100 mm during machine commissioning to accommodate different material thicknesses without adding external dead stops.
Product Size Changeovers
Quickly reconfigure assembly line strokes for new product runs by turning the rear adjuster screw, avoiding the need to physically unbolt and replace the entire cylinder.
Light-Duty Clamping
Apply up to 402 N of clamping force at 0.5 MPa while fine-tuning the exact clamping depth to prevent damaging delicate components.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-75 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa but demands a highly flexible travel window between 25 and 100 mm. If you need less adjustability, a standard SAI32X100 fixed-stroke cylinder is simpler, but this SAIJ variant excels in product changeovers. If your setup requires greater thrust, stepping up to the 40 mm bore yields 628 N of push force at the same pressure.
Because the 75 mm adjustment is significant relative to the 100 mm stroke, ensure your external guide rails manage side loads, as the 12 mm rod cannot absorb high lateral forces. This SAIJ32X100-75 uses a PT tapered port thread, lacks a standard magnet for sensors, and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. It is dimensionally interchangeable per ISO 15552.

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 SAIJ32X100-75 FAQ
The rear adjuster screw lets you mechanically shorten the retract stroke by up to 75 mm from the 100 mm nominal length, providing an effective travel window of 25 to 100 mm. It functions as a physical stop to set the end position and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the 32 mm bore generates 402 N of push force and 345 N of pull force. The standard speed range for this bore size is 30-800 mm/s, operating with a G1/8 port.
