About the Airtac SAI50 Standard Cylinder SAI50BX165S
The AirTAC SAI50X165-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 165mm stroke. It delivers a robust push force of 982 N at 0.5 MPa, making it well-suited for mid-range industrial actuation tasks.
This specific configuration includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and a PT tapered port thread. Equipped with a standard magnet (-S), the extruded aluminum barrel features dual sensor grooves allowing seamless integration with CMSE or DMSE reed switches for precise position detection.

Where the Airtac SAI50 Standard Cylinder SAI50BX165S Is Used
Stainless Clamping
Ideal for packaging machinery where the SUS304 rod resists washdown moisture while providing 982 N of clamping force.
Product Diverting
The 165mm stroke provides precise lateral movement on conveyor lines to sort products into secondary lanes.
Pallet Stops
Acts as a heavy-duty pneumatic stop gate in pallet handling systems, using dual sensor grooves for timing.
Is the Airtac SAI50 Standard Cylinder SAI50BX165S the Right Cylinder?
Selecting this 50mm bore over the smaller 40mm variant provides a significant force jump from 628 N to 982 N at 0.5 MPa, whereas stepping up to a 63mm bore yields 1559 N. The 165mm stroke offers ample travel for clamping and lifting mechanisms.
Because the 165mm stroke is below the 300mm threshold, rod bearing bending is minimal. However, for applications experiencing heavy side loads, pairing this cylinder with an external guide is recommended. Note that the standard adjustable air cushions only decelerate the piston at stroke ends; they do not hold a load. If pressure drops, the rod will drift. For true position holding without live air pressure, specify an SAIL (air-released lock) or BSAI (clamp-lock) variant. As a genuine ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders, utilizing a G1/4 port and compatible with FA/FB flange or LB foot mounting 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 SAI50 Standard Cylinder SAI50BX165S FAQ
At a standard 0.5 MPa operating pressure, this 50mm bore cylinder provides 982 N of push force and 825 N of pull force. It can reach up to 1767 N push at 0.9 MPa.
Yes. The SAI50X165-S is a true ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 cylinders from various brands. Just ensure your setup uses the G1/4 port and appropriate flange or foot brackets.
