About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-10S
The AirTAC SAIJ100X350-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 340 to 350 mm, allowing you to dial back the nominal 350 mm stroke by up to 10 mm during commissioning. Delivering a push force of 3927 N at 0.5 MPa, it handles substantial workloads with precision.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered ports. The extruded aluminum barrel features sensor grooves on both sides, and the integrated magnet (-S) is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for exact position feedback.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-10S Is Used
Machine Setup Tuning
Fine-tune the 340-350 mm end position during initial machine commissioning without fabricating external stopper blocks.
Product Size Changeover
Quickly adapt the stroke end on production lines running multiple product sizes by adjusting the rear screw.
Heavy Assembly Press
Leverage the 3927 N push force at 0.5 MPa for robust clamping while dialing in the exact final position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-10S the Right Cylinder?
Select this 100 mm bore when a 50 mm bore (982 N push at 0.5 MPa) is insufficient for your load. Choose the SAIJ adjustable-stroke design over a fixed SAI when you need variable end-stops for product changeovers without swapping the physical cylinder. For replacement, verify the 100 mm bore, 350 mm stroke, 10 mm adjustment, PT ports, and the -S magnet.
Because the 350 mm stroke is substantial, ensure proper external guiding to prevent side-load damage to the rod. Note that the rear adjuster acts only as a travel stop to decelerate the load; it does not hold the load without live air. For true load-holding without pressure, consider an external rod lock or AirTAC SAIL/BSAI models.
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 SAIJ100BX350-10S FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 10 mm. This creates a usable travel window of 340 to 350 mm, enabling fine-tuning of the end position without swapping the cylinder.
At 0.5 MPa operating pressure, the SAIJ100X350-10-S provides a push force of 3927 N and a pull force of 3681 N. At the maximum pressure of 1.0 MPa, the push force reaches 801 kgf.
