About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-100S
The AirTAC SAIJ160X225-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 125 to 225 mm. It delivers substantial thrust, pushing 14074 N at 0.7 MPa and pulling 9425 N, making it suited for heavy-duty positioning. The piston rod is SUS304 stainless steel, offering high corrosion resistance for harsh environments.
This model includes a magnet for position sensing via CMSE reed or DMSE electronic solid-state switches fitted into the dual-side sensor grooves. The PT tapered port and M36x2 rod thread provide robust mechanical connections. The rear adjuster acts purely as a travel stop to fine-tune the end position without swapping cylinders, but it will not hold the load without live air pressure.
For load-holding without continuous pressure, a SAIL or BSAI lock variant is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-100S Is Used
Heavy-Duty Pressing
Provides 14074 N of thrust at 0.7 MPa for assembling large components, with the 100 mm adjuster allowing precise depth control during setup.
Product Changeovers
Dial in the retract distance from 125 to 225 mm instantly when switching part sizes on a conveyor line, avoiding mechanical stop replacements.
Washdown Handling
The SUS304 stainless steel rod withstands corrosive washdown environments while driving heavy actuators in food or chemical processing.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-100S the Right Cylinder?
Selecting this 160 mm bore over a smaller 125 mm unit upgrades your thrust from 8590 N to 14074 N at 0.7 MPa, while stepping up to a 200 mm bore would yield 21991 N. The 100 mm adjustment range is ideal for product changeovers on a line, allowing you to dial in the exact retract distance during commissioning rather than machining external stops. When replacing an ISO 15552 cylinder, match the 160 mm bore, 225 mm stroke, PT port, and SUS304 rod. Because the stroke is 225 mm, ensure adequate external guiding for long unsupported loads to prevent rod 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 SAIJ160 Adjustable Cylinder SAIJ160BX225-100S FAQ
At 0.7 MPa, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. Its operating speed range is 30-500 mm/s.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel down from the 225 mm nominal stroke to as little as 125 mm. It only sets the end position and does not lock or hold the load without live air pressure.
