About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX55-10
The AirTAC SAIJ100X55-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position during commissioning. Based on a 55 mm nominal stroke, the external screw stopper provides a usable travel window of 45 to 55 mm, letting you dial in the exact retract distance without adding external stops or swapping the cylinder.
It uses PT tapered port threads (G1/2) and includes variable air cushions at both ends to manage deceleration across its 30-800 mm/s speed range.

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 SAIJ100AX55-10 Is Used
Product Changeover
Dial in the exact retract position within the 45-55 mm window when switching a production line to a new product size, avoiding the need to physically swap cylinders.
Commissioning Fine-Tune
Trim the effective stroke by up to 10 mm during initial machine setup to perfectly align the end-of-stroke tooling without adding bulky external stopper blocks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX55-10 the Right Cylinder?
Choose this 100 mm bore adjustable-stroke cylinder when your application requires high thrust combined with precise end-position tuning at machine setup or product changeover. The SAIJ100X55-10 is selected over a fixed-stroke SAI when you need a variable end-stop to accommodate minor product size changes on the line.
Because the stroke is only 55 mm, side-load stress on the 25 mm rod is minimal, though long unsupported strokes still require an external guide. To replace an ISO 15552 cylinder, match the 100 mm bore, 55 mm stroke, 10 mm adjustment range, PT G1/2 port, and your desired mounting option from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series.
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 SAIJ100AX55-10 FAQ
It features an external adjusting screw at the rear that acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 10 mm. This creates a usable travel window of 45 to 55 mm, enabling fine end-position tuning at commissioning without changing the cylinder itself.
At 0.9 MPa, the push force increases to 7068 N.
