About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX20-10
The AirTAC SAIJ100X20-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a usable travel window of 10 to 20 mm.
This adjustable-stroke design allows you to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, and it utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) that omits FB, CA, CB, and CR brackets.

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 SAIJ100AX20-10 Is Used
Machine Setup & Changeover
Dial in the exact 10 to 20 mm retract position during product size changes on a packaging line without replacing the entire cylinder or adding external stopper blocks.
Variable End-Stop Positioning
Fine-tune the end-of-stroke position during initial commissioning to achieve precise mechanical alignment, absorbing setup tolerances directly via the rear adjuster.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX20-10 the Right Cylinder?
The adjustable 10 mm window is ideal for product changeover on a line where exact end-position tuning is required, replacing a fixed-stroke SAI cylinder.
When matching an ISO 15552 replacement, verify the 20 mm stroke, 10 mm adjustment, PT G1/2 port, and your required mounting bracket. Note that the rear adjuster acts strictly as a travel stop, not a lock; a plain SAIJ does not hold loads without live air, so for load-holding without pressure, consider an SAIL or BSAI cylinder. Because the 25 mm rod and M20x1.5 thread handle high side loads well, no external guide is needed for this short 20 mm stroke.
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 SAIJ100AX20-10 FAQ
The SAIJ100X20-10 has a nominal 20 mm stroke with a 10 mm adjustment range, creating a usable travel window of 10 to 20 mm. A rear screw acts as a stopper to shorten the effective stroke, but it is not a lock and cannot hold the load without live air pressure.
