About the Airtac SAI50 Standard Cylinder SAI50BX165
The AirTAC SAI50X165 is a double-acting ISO 15552 profile cylinder offering a 50mm bore and 165mm stroke. It delivers 982N of push force at 0.5 MPa, making it well-suited for mid-range industrial actuation tasks.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. As a tie-rod-less extruded aluminum profile cylinder, it provides a clean, standardized mounting interface that is dimensionally interchangeable with other ISO 15552 actuators.

Where the Airtac SAI50 Standard Cylinder SAI50BX165 Is Used
Part Ejection
Provides reliable push force to eject machined components from a fixture, utilizing the 165mm stroke to clear the work area completely.
Package Diversion
Actuates routing gates on a packaging line, using 982N of thrust at 0.5 MPa to push heavy cartons onto secondary conveyors.
Material Lifting
Raises lower platforms or tooling stages in light assembly machinery where a compact 50mm profile cylinder footprint is required.
Is the Airtac SAI50 Standard Cylinder SAI50BX165 the Right Cylinder?
Select this 50mm bore when an application requires more power than the 40mm version (628N at 0.5 MPa) but without the bulk of a 63mm cylinder (1559N). The 165mm stroke provides ample extension for ejecting or lifting parts. If your mechanism must maintain its position after air pressure is removed or exhausted, do not rely on the standard adjustable air cushions; instead, specify the SAIL variant with an air-released lock or use an external pilot-operated check valve.
For a seamless direct replacement, match the 50mm bore, 165mm stroke, G1/4 port, and your required mounting accessory (such as FA flange or TC trunnion). Because this configuration lacks the -S magnet suffix, it cannot host CMSE or DMSE electronic sensors.
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 SAI50 Standard Cylinder SAI50BX165 FAQ
At 0.5 MPa operating pressure, this 50mm bore cylinder provides 982N of push force and 825N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374N.
Yes. The SAI50X165 is a true ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 cylinders of the same bore and stroke. Ensure your system uses the matching G1/4 port.
