About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-100S
The AirTAC SAIJ100X550-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 450 to 550 mm, allowing you to dial back the nominal 550 mm stroke by up to 100 mm during commissioning without adding external stops.
This unit includes a SUS420J2 stainless steel rod for corrosion resistance and an integrated magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. The rear screw acts as a travel stop to fine-tune the end position, but it does not hold the load without live air pressure.

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 SAIJ100AX550-100S Is Used
Variable End Stops
Set precise retract positions for machining operations that require different material off-sets without changing the physical cylinder mounting.
Machine Setup Changeover
Quickly trim the 550 mm stroke back by up to 100 mm during product line changeovers to accommodate varying package or part sizes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-100S the Right Cylinder?
If your application requires less force, stepping down to the 80 mm bore yields 4523 N at 0.9 MPa. For higher force, the 125 mm bore provides 11045 N. The PT tapered G1/2 port matches the 100 mm bore standard.
Because the 550 mm stroke is substantial, long unsupported travel demands an external guide to prevent side-load damage. The rear adjuster is a stop, not a lock; if you need true load-holding without live air, select a SAIL or BSAI cylinder. This SAIJ model uses the reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ100AX550-100S FAQ
The pull force is 3681 N at 0.5 MPa due to the rod.
The rear adjuster screw lets you shorten the effective travel from 550 mm down to 450 mm. This creates a 100 mm tuning window for end-position setup without swapping cylinders, but it acts as a stop and does not lock the load.
