About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X450-30
The AirTAC SAIJ100X450-30 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to dial back the 450 mm nominal stroke by up to 30 mm. This creates a 420-450 mm usable travel window, enabling precise end-position tuning at commissioning without swapping out the entire actuator or adding external stop blocks.
Because this model lacks a magnet, it relies on external positioning or mechanical stops rather than internal CMSE or DMSE sensors. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting if a magnet is added later. Furthermore, the rear adjuster functions purely as a travel stop and does not lock the load without live air pressure; for dead-air holding, consider the SAIL or BSAI variants.

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 SAIJ100X450-30 Is Used
Product Changeovers
Dial in the 420-450 mm retraction stop instantly when switching between product sizes on a packaging line, avoiding the need to physically swap cylinders or re-machine external stopper blocks.
Variable End Stops
Implement a flexible physical stop for automated material handling equipment, allowing operators to quickly adjust the travel distance by up to 30 mm based on the specific batch requirements.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X450-30 the Right Cylinder?
If you need less force, stepping down to an 80 mm bore yields 2513 N, whereas moving up to a 125 mm bore provides 6136 N. The adjustable stroke is ideal for product-size changeovers on a line, giving you a 420-450 mm window to fine-tune retraction without fabricating new hard stops.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 450 mm stroke, 30 mm adjustment range, G1/2 port, and mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. Given the 450 mm stroke, the 25 mm rod and M20x1.5 thread handle significant loads, but an external guide rail is recommended to prevent side-loading damage over this long travel distance.
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 SAIJ100X450-30 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster acts as a mechanical stop that shortens the 450 mm nominal stroke by up to 30 mm, providing a usable travel window of 420-450 mm. It only sets the travel end and does not hold the load without continuous air pressure.
