About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX225-20S
The AirTAC SAIJ100X225-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 205 to 225 mm, allowing you to dial back the nominal 225 mm stroke by up to 20 mm during machine commissioning. In the 100 mm bore class, it delivers a push force of 5497 N at 0.7 MPa, making it well-suited for heavy-duty positioning tasks.
This variant integrates a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. It supports AirTAC CMSE reed and DMSE electronic sensors fitted into the dual-side extruded aluminum barrel grooves. The rear adjuster acts purely as a mechanical stop to fine-tune the end position, while variable air cushions at both ends manage deceleration.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX225-20S Is Used
Machine Changeover
Dial in the exact 205-225 mm end-stop during product size changes without swapping out the entire cylinder or adding external shims.
Heavy Positioning
Leverage the 5497 N push force at 0.7 MPa to move heavy pallets or tooling carriages into precise final positions.
Automated Clamping
Use the fine-tuned travel limit to set accurate clamping depth on varying workpiece thicknesses, preventing over-travel damage.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX225-20S the Right Cylinder?
Choose this 100 mm bore adjustable-stroke cylinder when your equipment requires precise end-position tuning without fabricating external stops. If you need less force, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa; if your application demands even higher thrust, moving to a 125 mm bore provides 8590 N at 0.7 MPa. Because the 225 mm stroke exceeds 200 mm, ensure an external guide supports the load to prevent excessive side-loading on the M20x1.5 rod thread.
The rear adjuster screw and air cushions only set the travel end and deceleration; they do not hold the load without live air pressure. For drop-prevention or true load-holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) series. This SAIJ100X225-20-S variant features PT tapered port threads (G1/2), a SUS304 rod, and a magnet for sensors. It is dimensionally interchangeable per ISO 15552 and uses the SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100BX225-20S FAQ
At a standard operating pressure of 0.7 MPa, this 100 mm bore cylinder generates a push force of 5497 N and a pull force of 3681 N. At the maximum rated pressure of 1.0 MPa, it can deliver up to 801 kgf of push force.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from the nominal 225 mm down to 205 mm. It is a travel stop and deceleration setter, not a lock, so it will not hold a load without continuous air pressure.
