About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-75S
The AirTAC SAIJ100X475-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. The integrated -75 adjuster screw creates a 400-475mm usable travel window, allowing you to dial in the exact end position during commissioning without adding external stops.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and an -S magnet for electronic DMSE or reed CMSE sensors. The extruded aluminum barrel carries sensor grooves on both sides. Remember that the rear adjuster acts only as a travel stop to set deceleration, not as a load-holding lock; use a SAIL or BSAI cylinder if static holding without live air is required.

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 SAIJ100BX475-75S Is Used
Machine Setup & Changeover
Fine-tune the 400-475mm travel window during product line changeovers to accommodate varying package sizes without swapping out the cylinder.
Variable End-Stop Positioning
Dial in the exact retraction point during initial commissioning to synchronize multiple actuators on a large assembly fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-75S the Right Cylinder?
The 475mm stroke exceeds 300mm, so an external guide is strongly recommended to prevent side-loading damage to the M20x1.5 piston rod.
An adjustable SAIJ is preferred over a fixed SAI when machine setups require fine end-position tuning. To match this ISO 15552 interchangeable cylinder, specify: 100mm bore, 475mm stroke, -75mm adjustment, PT G1/2 ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet.
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 SAIJ100BX475-75S FAQ
The rear adjuster screw lets you shorten the nominal 475mm stroke by up to 75mm, providing a usable travel window of 400-475mm. It acts as a mechanical stop to tune the end position, but it is not a lock and will not hold the load without live air pressure.
At the maximum operating pressure of 1.0 MPa, the push force increases to 801kgf.
