About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-75S
The AirTAC SAIJ100X90-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a highly flexible usable travel window of 15-90 mm. Delivering 3927 N of push force at 0.5 MPa, this carbon-rod unit handles substantial loads while allowing precise end-position tuning during commissioning. It features a PT tapered port (G1/2) and operates at speeds of 30-800 mm/s.
Because the adjuster acts purely as a mechanical stop and does not lock the load, live air must be maintained to hold position; for pilot-operated check valve or lock requirements, consider the SAIL or BSAI series. This -S variant includes a magnet for CMSE reed and DMSE electronic sensors, which seat neatly into the dual-side extruded aluminum barrel grooves.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-75S Is Used
Product Changeover
Dial in the 15-90 mm travel window rapidly on packaging lines when switching between different container sizes without changing the cylinder.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to perfect the seating force of large 100 mm bore assemblies.
Variable End Stops
Use the rear screw to create adaptable travel limits on automated welding fixtures, leveraging 3927 N of thrust at 0.5 MPa.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-75S the Right Cylinder?
Choose this 100 mm bore when a 80 mm bore (2513 N push at 0.5 MPa) lacks thrust, but a 125 mm bore is physically oversized. The 75 mm adjustment range is ideal for machines requiring variable end-stops or frequent product-size changeovers, eliminating the need to swap cylinders or bolt on external stops. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
To match this exact ISO 15552 interchangeable cylinder, specify: 100 mm bore, 90 mm stroke, 75 mm adjust, PT port thread, carbon steel rod, and the -S magnet option. Since the stroke is under 300 mm, side-load stress on the 25 mm rod and M20x1.5 thread is moderate, though external guides are still recommended for heavy off-center loads.
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 SAIJ100X90-75S 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 90 mm nominal stroke by up to 75 mm, creating a usable travel window of 15-90 mm. It functions as a mechanical stop and does not lock the load without live air pressure.
