About the Airtac SAI125 Standard Air Cylinder SAI125BX95
The AirTAC SAI125X95 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 6136 N of push force at 0.5 MPa, this non-standard 95 mm stroke unit is manufactured to order for specialized movement profiles. The extruded aluminum barrel design omits tie rods for a clean exterior while maintaining strict dimensional interchangeability per ISO 15552 standards.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in harsh or washdown environments. It utilizes tapered PT threads for pneumatic connections and is built without a magnet. For applications requiring position holding upon air loss, this base model should be paired with the SAIL locking variant or an external rod lock.

Where the Airtac SAI125 Standard Air Cylinder SAI125BX95 Is Used
Heavy Metal Stamping
Provides the high kinetic energy and 6136 N thrust required to form thick-gauge metal sheets in automated stamping presses.
Large Mold Clamping
Secures substantial injection molds or heavy tooling plates securely in place during high-force manufacturing cycles.
Pallet Diverting
Actuates heavy-duty diverters on high-mass pallet conveyor lines where lower-force cylinders would stall under friction.
Is the Airtac SAI125 Standard Air Cylinder SAI125BX95 the Right Cylinder?
Selecting this 125 mm bore cylinder makes sense when your application requires substantial thrust that smaller bores cannot provide. If 6136 N at 0.5 MPa is excessive, stepping down to an 80 mm bore yields 2513 N, optimizing air consumption. Conversely, moving up to a 160 mm bore provides 10053 N for extreme load moving.
Because this is a custom 95 mm stroke, ensure your mounting arrangement accommodates the exact extended length. The SAI125X95 uses PT port threads and operates at a maximum speed of 30-500 mm/s. As a standard double-acting cylinder, it relies entirely on live air pressure to move and hold loads; it will drift if pressure is lost. For drop-in compatibility, match your existing ISO 15552 mounting footprint using standard FA or FB flange accessories.
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 SAI125 Standard Air Cylinder SAI125BX95 FAQ
At 0.5 MPa, the SAI125X95 generates 6136 N of push force and 5734 N of pull force. If operating pressure increases to 0.7 MPa, the push force rises to 8590 N.
Yes, the SAI125X95 is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 standard cylinders of the same bore size. Always match your existing mounting accessories and PT port connections.
