About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX450-30S
The AirTAC SAIJ100X450-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the travel by up to 30 mm. This yields a usable stroke window of 420-450 mm, perfect for fine-tuning end positions during commissioning without swapping out the physical unit.
This SKU features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a built-in magnet (-S) for electronic position sensing. The extruded aluminum barrel incorporates sensor grooves on both sides, seamlessly accepting AirTAC DMSE solid-state or CMSE reed switches. It uses a G1/2 port and relies on variable air cushions at both ends to decelerate the load smoothly.

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 SAIJ100AX450-30S Is Used
Machine Setup Changeover
Dial in the exact end-of-stroke position within the 420-450 mm window during product line changeovers without adding external stopper blocks.
Variable End Stops
Adjust the retract distance on the fly to accommodate different package sizes or pallet dimensions moving down a handling line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX450-30S the Right Cylinder?
An adjustable stroke is ideal for machine setups requiring variable end stops or frequent product-size changeovers, saving the cost of fixed-stroke SAI replacements. For any stroke length of 450 mm, guiding the load externally is critical to prevent excessive side-loading on the 25 mm rod.
To match this ISO 15552 interchangeable cylinder, specify a 100 mm bore, 450 mm nominal stroke, 30 mm adjustment range, PT tapered ports, and the -S magnet option. Remember that the rear adjuster acts only as a travel stop; it will not hold a load without live air pressure. For true load-holding, select a SAIL or BSAI series cylinder instead.
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 SAIJ100AX450-30S FAQ
It operates at speeds between 30 and 800 mm/s.
A rear screw stopper lets you shorten the nominal 450 mm stroke by up to 30 mm, creating a usable travel window of 420-450 mm. This stopper only sets the end position; it does not lock the load without live air.
