About the Airtac SAI50 Standard Cylinder SAI50AX170
The AirTAC SAI50X170 is a double-acting ISO 15552 profile cylinder offering a 982 N push force at 0.5 MPa. Its 170 mm stroke is well-suited for mid-range linear actuation tasks requiring reliable throughput. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that resists debris buildup.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads and does not include a magnet, meaning it is optimized for purely mechanical drive rather than direct position sensing.

Where the Airtac SAI50 Standard Cylinder SAI50AX170 Is Used
Package Diverting
Provides the 982 N force needed to push heavy cartons across transfer belts without stalling.
Clamp Pressing
Strokes 170 mm to secure workpieces in mid-size machining centers prior to cutting operations.
Pallet Stopping
Decelerates inbound pallets on gravity rollers using its adjustable end cushions.
Is the Airtac SAI50 Standard Cylinder SAI50AX170 the Right Cylinder?
Select this 50 mm bore when an application demands more power than a 40 mm bore (628 N at 0.5 MPa) but does not warrant the bulk of a 63 mm bore (1559 N at 0.5 MPa). The 170 mm stroke falls under standard lengths, so no made-to-order lead times apply. To integrate this unit, match the PT G1/4 port, choose an ISO 15552 mounting accessory like an FA flange or TC trunnion, and note that a magnet (-S) must be specified if you later require CMSE or DMSE sensor switches.
Because the stroke is under 300 mm, standard rod bearing bending is minimal, but heavy radial loads still require an external guide. Note that the adjustable air cushions at both ends decelerate the piston but do not lock the load; if pressure drops, the rod drifts. For fail-safe holding, use the SAIL pneumatic lock variant.
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.
