About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X75-10S
The AirTAC SAIJ100X75-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 65-75 mm usable travel window, letting you trim the 75 mm nominal stroke by up to 10 mm during commissioning. In the 100 mm bore class, it delivers 3927 N of push force at 0.5 MPa and uses a G1/2 port with an M20x1.5 rod thread.
This -S variant includes a magnet for CMSE reed and DMSE electronic sensors, fitting neatly into the extruded aluminum barrel's dual sensor grooves. The rear stopper screw sets the retract end position without requiring external stops, though it acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X75-10S Is Used
Press Stroke Calibration
Dial in the exact 65-75 mm end position during press setup to accommodate material thickness variations without changing hardware.
Product Changeover
Quickly adjust the retract stop on a packaging line when switching to a different package size, minimizing downtime.
End-Stop Tuning
Fine-tune the final resting position of high-force tooling to prevent mechanical interference during commissioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X75-10S the Right Cylinder?
Choose this 100 mm bore when you need heavy thrust beyond the 2513 N push force of an 80 mm cylinder at 0.5 MPa, but step down if 3927 N is excessive for your fixture. The 10 mm adjustment window is ideal for fine-tuning end positions during machine setup or product changeover, avoiding the need to swap a fixed-stroke SAI cylinder. When specifying an ISO 15552 replacement, match the 75 mm stroke, 10 mm adjuster, PT port thread, and -S magnet.
For load-holding without continuous air pressure, note that the SAIJ adjuster and air cushions do not function as a lock; consider an AirTAC SAIL or BSAI cylinder instead. With a 75 mm stroke, side-load risks are minimal, but always ensure the M20x1.5 rod is properly aligned. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100X75-10S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the 75 mm nominal stroke by up to 10 mm, providing a usable travel window of 65 to 75 mm. It acts as a mechanical stop and does not lock the load without air pressure.
