About the Airtac SAI50 Standard Cylinder SAI50BX80
The AirTAC SAI50X80 is a double-acting ISO 15552 profile cylinder featuring an 80 mm stroke and a 50 mm bore. It delivers a push force of 982 N at 0.5 MPa, making it well-suited for medium-duty handling and positioning tasks. The extruded aluminum barrel omits tie-rods, presenting a clean profile that matches standardized ISO 15552 mounting dimensions for straightforward machinery integration.
This specific configuration incorporates a SUS304 stainless steel piston rod (material code B), providing excellent corrosion resistance for environments with moisture or washdown requirements. It utilizes PT tapered port threads and is built without a magnet. For high-temperature environments up to 70 C, the standard TPU seals can be swapped for Viton (code H) or NBR (code N) options.

Where the Airtac SAI50 Standard Cylinder SAI50BX80 Is Used
Component Clamping
Provides 982 N of push force at 0.5 MPa to securely hold aluminum or steel workpieces during machining and drilling operations.
Package Diverting
Executes rapid 80 mm linear strokes to push cartons or totes between adjacent conveyor lanes in sorting facilities.
Gate Control
Actuates small access doors and machine safety gates, utilizing the SUS304 stainless steel rod to resist corrosion in industrial environments.
Is the Airtac SAI50 Standard Cylinder SAI50BX80 the Right Cylinder?
At 0.5 MPa, this 50 mm bore generates 982 N of push force. If your application requires less force, stepping down to a 40 mm bore yields 628 N, while moving up to a 63 mm bore provides 1559 N for heavier payloads. Because the 80 mm stroke is relatively short, rod-bearing bending from side loads is minimal compared to longer strokes.
This model uses G1/4 PT ports and supports standard ISO 15552 mounting accessories like FA foot brackets or TC trunnion joints. Remember that a standard SAI cylinder relies on live air pressure to hold position; if pneumatic pressure drops, the piston will drift. For fail-safe load holding without continuous air, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-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 SAI50BX80 FAQ
At a standard operating pressure of 0.5 MPa, the SAI50X80 generates a push force of 982 N and a pull force of 825 N. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X80 is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders with a 50 mm bore and 80 mm stroke, matching the G1/4 port and mounting interface.
