About the Airtac SAI50 Standard Cylinder SAI50X155
The AirTAC SAI50X155 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 155mm stroke. It generates 982N of push force at 0.5MPa, making it a robust choice for mid-range automation tasks.
This model incorporates a standard carbon steel piston rod and utilizes PT tapered port threads. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing for flexible mounting of reed or solid-state switches when position feedback is required.

Where the Airtac SAI50 Standard Cylinder SAI50X155 Is Used
Material Handling
Ideal for diverting and routing packages on assembly lines where 982N of thrust easily pushes standard totes.
Assembly Clamping
Provides reliable holding force for medium-duty jigs and fixtures during machining or joining processes.
Pallet Positioning
Excellent for lifting and positioning lightweight pallets or product stacks at ergonomic workstations.
Is the Airtac SAI50 Standard Cylinder SAI50X155 the Right Cylinder?
Providing 982N at 0.5MPa, this 50mm bore sits comfortably between the 40mm (628N) and 63mm (1559N) options. For applications needing less force, the 40mm bore is a lighter alternative; for heavier payloads, the 63mm bore offers significantly higher thrust.
Because the 155mm stroke is below the 300mm threshold, side-load stress on the rod bearing is minimal. However, if your mechanism loses air pressure, the piston will drift and cannot hold a load vertically; for dead-drop prevention, consider the SAIL locking variant or an external pilot check valve. As a true ISO 15552 profile cylinder, it serves as a direct replacement matching the 50mm bore, 155mm stroke, PT G1/4 port, and standard mounting accessories like FA flanges or LB foot brackets.
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 SAI50X155 FAQ
