About the Airtac SAI50 Standard Cylinder SAI50BX105S
The AirTAC SAI50X105-S is a double-acting ISO 15552 profile cylinder offering a 982 N push force and 825 N pull force at 0.5 MPa. Because the 105 mm stroke is a non-standard made-to-order length, it provides exact mid-stroke positioning for specialized machinery rather than relying on adjustable stops.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes a built-in magnet (-S) for seamless integration with CMSE or DMSE reed sensors along the dual grooves of the extruded aluminum barrel. It uses tapered PT ports and adjustable air cushions at both ends to manage end-of-stroke impact.

Where the Airtac SAI50 Standard Cylinder SAI50BX105S Is Used
Mid-Stroke Clamping
Provides exact 105 mm extension for clamping irregularly sized workpieces where a 100 mm stroke falls short.
Diverter Gate Actuation
Drives sorting gates on packaging lines, utilizing the -S magnet and CMSE sensors for precise position confirmation.
Corrosive Environment Handling
Moves parts in washdown areas safely thanks to the SUS304 stainless steel rod resisting moisture and chemicals.
Is the Airtac SAI50 Standard Cylinder SAI50BX105S the Right Cylinder?
Select this 50 mm bore when a 40 mm bore (628 N push at 0.5 MPa) lacks thrust, but a 63 mm bore (1559 N push) is oversized. The 105 mm stroke is made-to-order; if your machine only needs 100 mm or 125 mm of travel, choosing those standard strokes ensures faster delivery.
As a true ISO 15552 profile cylinder, it mounts interchangeably with other ISO 15552 profile cylinders using standard FA flanges or LB foot brackets. Note that this standard cylinder does not hold loads safely upon loss of air pressure; for drop prevention, specify the SAIL variant with an air-released lock.
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 SAI50BX105S FAQ
