About the Airtac SAI80 Standard Air Cylinder SAI80X50
The AirTAC SAI80X50 is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 2513 N push force at 0.5 MPa across its 50 mm stroke. This extruded aluminum barrel design omits tie-rods, offering a sleek, standardized mounting interface that drops in seamlessly with other ISO 15552 cylinders.
For demanding thermal environments, you can specify Viton (H) seals instead of the standard TPU to handle higher operating temperatures. The barrel also features integrated sensor grooves on both sides, allowing you to easily mount CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI80 Standard Air Cylinder SAI80X50 Is Used
Package Diversion
Provides the high lateral force needed to push heavy cartons off a main conveyor belt onto packing chutes.
Press Fit Operations
Delivers consistent 2513 N thrust at 0.5 MPa for seating bearings and bushings into machined housings.
Clamp Actuation
Drives heavy-duty pneumatic clamps to secure large metal workpieces during welding or machining.
Is the Airtac SAI80 Standard Air Cylinder SAI80X50 the Right Cylinder?
If your application requires slightly less force, stepping down to the 63 mm bore yields 1559 N at 0.5 MPa, while moving up to the 100 mm bore provides 3927 N for heavier loads. Because this 50 mm stroke is relatively short, rod-bearing bending from side loads is minimal, but you should still ensure axial load alignment to maximize seal life.
To match this exact model, specify an 80 mm bore, 50 mm stroke, PT tapered port thread, and standard carbon steel rod material. Mounting accessories like the FA flange or TC trunnion can be added to suit your frame. Remember that a standard SAI cylinder relies on continuous air pressure to hold a load; if pneumatic pressure drops, the piston will drift, so consider the SAIL variant for pneumatic locking.
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.
