About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX375-10S
The AirTAC SAIJ100X375-10-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster. It delivers a robust 5497N push force at 0.7 MPa. The built-in stopper provides a usable travel window of 365-375 mm, allowing you to fine-tune the retract end position by up to 10 mm during commissioning without external stops.
This SKU includes a SUS304 stainless steel rod for superior corrosion resistance and a magnet for CMSE reed or DMSE electronic sensors. It uses a G1/2 port and features variable air cushions at both ends. Because the 375 mm stroke is long, an external guide is recommended to manage side loads and prevent rod deflection.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX375-10S Is Used
Machine Setup Tuning
Dial in the exact 365-375 mm end position during machine commissioning without swapping cylinders or adding external stopper blocks.
Product Changeover
Quickly adjust the retract stop up to 10 mm to accommodate slight variations in product size on a packaging line.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod to push 5497N at 0.7 MPa in washdown or mildly corrosive manufacturing environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX375-10S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when your machine setup requires precise end-position tuning or frequent product changeovers. The rear adjuster acts purely as a travel stop to set deceleration; it does not hold the load without live air. For true position holding, consider an AirTAC SAIL or BSAI cylinder.
When matching ISO 15552 dimensions for replacement, verify the 100 mm bore, 375 mm stroke, 10 mm adjustment, PT tapered port, and the -S magnet option. If your application requires less force, the 80 mm neighbor bore offers 3518N push at 0.5 MPa. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100BX375-10S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 10 mm. This creates a usable travel window of 365-375 mm. The adjuster only sets the travel end and does not lock or hold the load without live air pressure.
At 0.7 MPa operating pressure, the SAIJ100X375-10-S provides 5497N of push force and 3681N of pull force. It can deliver a maximum of 801 kgf at 1.0 MPa.
