About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-30S
The AirTAC SAIJ100X550-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 550 mm travel by up to 30 mm for a precise 520-550 mm usable window. It delivers substantial thrust, pushing 7068 N at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel retains standard ISO 15552 mounting dimensions while providing sensor grooves on both sides for flexible switch placement.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-30S Is Used
Product Changeover
Quickly adapt the end-of-stroke position on a packaging line when switching to different carton sizes, utilizing the 30 mm adjustment window to avoid mechanical rebuilds.
Heavy Press Tuning
Precisely set the forming depth on a 7068 N pressing application, using the rear stopper to dial in the exact 520-550 mm travel distance during commissioning.
Variable End Stops
Accommodate multiple material thicknesses on an automated assembly station by adjusting the retract distance rather than installing separate fixed-stroke cylinders.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-30S the Right Cylinder?
The 30 mm adjustment range is ideal for fine-tuning the retract end position during machine setup or product changeovers without swapping the cylinder. Because the stroke is 550 mm, the M20x1.5 piston rod is highly susceptible to side-loading; an external guide rail must be used to prevent binding and premature seal wear.
When specifying a replacement, ensure you match the 100 mm bore, 550 mm stroke, 30 mm adjustment, PT tapered port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ100AX550-30S FAQ
The rear adjuster acts as an external stopper that trims the effective travel back by up to 30 mm, creating a 520-550 mm usable stroke window. It sets the end position but does not lock the load without continuous air pressure.
At 0.9 MPa operating pressure, the push force is 7068 N and the pull force is 6625 N.
