Airtac SAIF Series Standard Cylinder with Valve SAIF80X50S-10A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X50S-10A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 50mm stroke and a built-in 4M310-10 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF80X50S-10A
The AirTAC SAIF80X50S-10A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-10 5/2 solenoid valve. This built-in valve provides an effective flow rate of Cv 1.68 and operates via an AC220V terminal coil connection. Because the valve manifold mounts directly to the extruded aluminum barrel, it eliminates the need for remote plumbing and saves valuable panel space. The assembly operates at 0.15-0.8 MPa, governed by the valve's pressure limits rather than the cylinder's 1.0 MPa rating. The carbon steel piston rod delivers a robust 2513 N push force at 0.5 MPa. Equipped with a magnet, this unit supports CMSE reed and DMSE electronic sensors for precise position tracking. Manifold connection utilizes O10 x O6.5 PU tubing to bridge the valve and cylinder ports.
By default, the factory setting retracts the rod when the coil is energised, but you can reconfigure the valve to extend-when-energised simply by repositioning it. The 5/2 valve relies on internal pilot pressure to hold its last position, meaning it routes air but does not mechanically lock the load. Operating at a maximum frequency of 4 cycles per second, this self-contained unit achieves a 0.05 s activation time, making it highly effective for decentralized automation stations across large machinery.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF80X50S-10A Is Used
Decentralized Automation Stations
Ideal for large assembly lines where running individual valve tubing back to a central manifold is costly and complex.
Space-Constrained Machinery
The integrated valve manifold saves critical panel and footprint space in tight machine enclosures while delivering 2513 N push force.
Retrofits and Upgrades
Perfect for upgrading existing ISO 15552 setups to self-switching control without adding external valve islands.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X50S-10A the Right Choice?
Choose this 80 mm bore SAIF model when your application requires substantial thrust—2513 N push at 0.5 MPa—along with the convenience of localized control. If you need less force, the 63 mm neighbor offers 1559 N push at 0.5 MPa, while stepping up to the 100 mm bore yields 3927 N. The integrated 4M310-10 valve features a 3/8" valve port, distinct from the cylinder's PT 3/8" port, ensuring optimal flow for high-speed actuation up to 800 mm/s. This self-valved configuration is superior to a separate cylinder and remote valve when decentralizing a machine, as it drastically reduces tubing runs and wiring complexity.
When specifying this exact replacement, verify the 50 mm stroke, PT tapered port threads, AC220V voltage, terminal electrical entry, and the -S magnet for CMSE/DMSE sensors. Since the stroke is under 300 mm, external side-load guides are less critical, but always ensure axial alignment to maximize seal life. For applications requiring the cylinder to hold its position without live air pressure, note that this 5/2 valve does not function as a lock; consider an AirTAC SAIL lock cylinder instead.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF80X50S-10A FAQ
The 80 mm bore cylinder provides a push force of 2513 N and pull force of 2268 N at 0.5 MPa. The built-in 4M310-10 5/2 valve offers an effective area of 30.0 mm2 (Cv 1.68).
It uses an AC220V terminal coil drawing 3.5 VA with an IP65 rating and 0.05 s response time. By default, the valve retracts the rod when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
