About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX50-50
The AirTAC SAIJ100X50-50 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a usable travel window of 0-50 mm, allowing you to dial in the exact end position during commissioning without swapping out the physical unit.
This model incorporates variable air cushions at both ends to decelerate the moving load, but the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. For load-holding requirements without continuous air, an external rod lock or related SAIL series is required. The extruded aluminum barrel includes sensor grooves on both sides, supporting CMSE reed and DMSE electronic switches if a magnet is specified later.

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 SAIJ100AX50-50 Is Used
Product Size Changeovers
Quickly adapt a packaging line to varying carton sizes by dialing the rear stopper across the 0-50 mm window, achieving precise end-position tuning without changing the cylinder.
Machine Setup Commissioning
Fine-tune the exact retracted position during initial machine commissioning, using the rear adjuster to set the 100 mm bore's stroke limit perfectly against mechanical hard stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX50-50 the Right Cylinder?
Select this 100 mm bore actuator when your application demands high thrust—up to 3927 N at 0.5 MPa—along with the flexibility to fine-tune the travel end. If your changeover process requires less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. The adjustable stroke is ideal for product-size changeovers on a line, eliminating the need to bolt on external stops. When matching an ISO 15552 replacement, verify the 50 mm adjustment range, PT tapered G1/2 port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), which omits FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ100AX50-50 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke by up to 50 mm. This provides a usable travel window of 0-50 mm, meaning the nominal 50 mm stroke can be dialed back to any position down to zero.
At the maximum 1.0 MPa pressure, it can generate up to 801 kgf.
