About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-10
The AirTAC SAIJ100X350-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 340-350 mm usable travel window, allowing you to dial back the nominal 350 mm stroke by up to 10 mm during commissioning without adding external stops. Delivering 3927 N of push force at 0.5 MPa, it handles substantial workloads while remaining dimensionally interchangeable with ISO 15552 cylinders.
This model features a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting. The rear adjuster acts purely as a travel stop to set end positions, not as a lock, and the cylinder will not hold loads without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-10 Is Used
Machine Setup Tuning
Dial in the exact 340-350 mm end position during initial commissioning to perfect pressing or clamping depth.
Product Changeover
Quickly adjust the travel stop by up to 10 mm when switching line sizes without swapping the cylinder.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for reliable actuation in washdown or mildly corrosive industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-10 the Right Cylinder?
Choose this 100 mm bore when 50 mm (982 N at 0.5 MPa) is too weak but 125 mm (6136 N at 0.5 MPa) is oversized. An adjustable stroke is preferred over a fixed SAI when you need fine end-position tuning during product changeovers. For load-holding without continuous air pressure, select a SAIL or BSAI cylinder instead, as the rear adjuster here is strictly a stop. To match this ISO 15552 replacement exactly, specify: 100 mm bore, 350 mm stroke, 10 mm adjustment, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet. Given the 350 mm stroke, ensure an external guide supports the rod to prevent excessive side loading.
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 SAIJ100BX350-10 FAQ
It provides 3927 N of push force and 3681 N of pull force at 0.5 MPa. At 0.9 MPa, the push force increases to 7068 N.
A rear screw stopper lets you trim the effective travel down from 350 mm to a minimum of 340 mm. It acts as a travel stop and does not lock the load without live air.
