About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX375-75S
It features a SUS304 stainless steel rod and a built-in magnet for position sensing. By turning the rear screw, you can trim the forward travel, creating a precise 300-375mm usable stroke window without swapping out the entire actuator.
This 100mm bore actuator uses a G1/2 port and relies on variable air cushions at both ends to decelerate heavy loads smoothly. The rear stopper functions purely as a travel end-position setter for product changeovers, not as a load-holding lock. For applications requiring position retention without live air pressure, an external rod lock or a related SAIL pneumatic lock cylinder 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 SAIJ100BX375-75S Is Used
Product Size Changeovers
Quickly fine-tune the 300-375mm stroke window during line changeovers to accommodate different package lengths without fabricating new mechanical stops.
Variable End-Stop Diverting
Act as an adjustable diverting gate on a conveyor system where the end position frequently shifts based on the dimensions of the goods being sorted.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX375-75S the Right Cylinder?
The 75mm adjustment range is highly beneficial on lines running multiple product sizes, allowing operators to dial in the exact end-stop during changeovers rather than adding physical spacers. Because this is a 375mm stroke, the 25mm diameter piston rod will experience leverage forces under heavy side loads, so an external guide rail should be used to prevent premature seal wear.
When matching this ISO 15552 dimensionally interchangeable cylinder for a replacement, verify the 100mm bore, 375mm nominal stroke, 75mm adjustment, PT tapered port threads, and the -S magnet for CMSE reed or DMSE electronic sensors. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, intentionally omitting FB, CA, CB, and CR brackets.
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 SAIJ100BX375-75S FAQ
At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the effective forward travel from the 375mm nominal stroke down to as little as 300mm. It sets the end position but does not lock the load without live air pressure.
