About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X75-75
The AirTAC SAIJ100X75-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. With a nominal 75 mm stroke and a 75 mm adjustment screw, it provides a highly flexible usable travel window of 0 to 75 mm. This wide trim range allows you to dial in the exact end position during commissioning without adding external stops. It delivers robust thrust, pushing 3927 N at 0.5 MPa and up to 7068 N at 0.9 MPa.
The 25 mm carbon steel rod and M20x1.5 thread provide excellent rigidity for heavy loads, while the extruded aluminum barrel includes sensor grooves on both sides. You can use AirTAC CMSE reed or DMSE electronic sensors by specifying the -S magnet option if needed. The rear adjuster acts purely as a mechanical stop for deceleration and positioning; it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X75-75 Is Used
Variable End-Stop Forming
Dial in the exact material press depth from 0 to 75 mm during setup, allowing rapid adaptation for different material thicknesses without changing cylinders.
Product Changeover Diverter
Adjust the retract position on the fly to handle varying package sizes on a packaging line, using the rear stopper to set the new resting point quickly.
Machine Setup Calibration
Fine-tune the end-of-stroke position during initial commissioning to perfectly align heavy tooling, using the 75 mm adjustment window to find the optimal operating point.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X75-75 the Right Cylinder?
Choose this 100 mm bore when an 80 mm cylinder (2513 N push at 0.5 MPa) is insufficient for your load, but a 125 mm bore (6136 N) is oversized. The SAIJ100X75-75 is selected over a fixed-stroke SAI when a machine requires variable end-stops or rapid product changeover. By turning the rear screw, you can shorten the effective stroke anywhere from 0 to 75 mm on the fly.
For drop-in replacements, match the 100 mm bore, 75 mm stroke, 75 mm adjustment, PT G1/2 port, and the mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, explicitly omitting FB, CA, CB, and CR. Because the 75 mm stroke is relatively short, side-load risks are minimal, but an external guide is still recommended for heavy lateral forces. If your process requires true load-holding without live air, consider the SAIL lock or BSAI clamp-lock series instead.
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 SAIJ100 Adjustable Cylinder SAIJ100X75-75 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 0.9 MPa, it delivers 7068 N of push force.
The rear adjuster screw lets you trim the effective travel back by up to 75 mm from the nominal 75 mm stroke, creating a 0 to 75 mm usable travel window. It acts as a mechanical stop to set the end position and does not lock or hold the load without continuous air pressure.
