About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-10S
The AirTAC SAIJ100X175-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 165-175 mm usable travel window, letting you dial back the nominal 175 mm stroke by up to 10 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles heavy positioning tasks.
This variant features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and includes a magnet (-S) for CMSE reed or DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-10S Is Used
Machine Setup Tuning
Fine-tune the 165-175 mm retract end-stop during machine commissioning to dial in exact positioning without machining new hard stops.
Product Changeover
Quickly adjust the travel window on automated lines when product sizes change, saving downtime by avoiding physical cylinder swaps.
Heavy Forming Press
Leverage the 3927 N push force at 0.5 MPa for heavy pressing and forming, using the rear screw to limit over-travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-10S the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (1559 N push at 0.5 MPa) is insufficient, but an 80 mm bore (2513 N) leaves no safety margin. The adjustable stroke is ideal for product changeovers, letting you fine-tune the retract end-position without adding external stops or swapping the cylinder. To replace an ISO 15552 cylinder, match the 175 mm stroke, 10 mm adjustment, PT G1/2 port, and -S magnet.
Because the stroke is 175 mm, ensure the load is guided externally to prevent side-load damage. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe holding, use a SAIL or BSAI cylinder. The M20x1.5 rod thread handles high side loads, but always use an external guide for unsupported masses.
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 SAIJ100AX175-10S 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 the maximum 1.0 MPa pressure, it delivers up to 801 kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 10 mm. This creates a 165-175 mm usable travel window for fine-tuning the end position at commissioning without altering the air cushions.
