Airtac SAIF Series Standard Cylinder with Valve SAIF80X500S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X500S-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 500mm stroke and a built-in 4M310-08 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 SAIF80X500S-08B
The AirTAC SAIF80X500S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve with a 1.40 Cv flow rate. Driven by a DC24V terminal coil drawing 3.0W, it eliminates the need for a separate remote valve, saving panel space and cutting plumbing in decentralized machine layouts. The assembly operates within a 0.15-0.8 MPa pressure range, as the built-in valve limits the 1.0 MPa cylinder rating. A carbon steel rod and magnetic piston are standard.
At 0.5 MPa, this 80mm bore generates 2513N of push force and 2268N of pull. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend on signal. The manifold connects to the cylinder via O10xO6.5 PU tubing, routing air from the 1/4 valve port to the 3/8 cylinder port. Position sensing is enabled with CMSE reed or DMSE electronic switches.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF datasheet. Port options: PT / G.
Theoretical Output Force (Ø80mm)

| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

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 SAIF80X500S-08B Is Used
Decentralized Automation
Perfect for large factory layouts where running remote valve tubing is costly, as the integrated 4M310 valve drives the 80mm bore directly from a single DC24V signal.
Long-Stroke Handling
With a 500mm stroke delivering 2513N push force at 0.5MPa, it suits long-travel material pushers, provided external guides manage the side-load.
Retrofit Assemblies
Ideal for upgrading existing ISO 15552 interchangeable machines where panel space is tight, adding self-switching pneumatic control without a separate valve manifold.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X500S-08B the Right Choice?
Select this self-valved unit when decentralizing actuation across large machines, as it switches itself from one coil signal without needing remote valve tubing. If your application requires less force, stepping down to the 63mm bore yields 1559N push at 0.5MPa. For heavier loads, the 100mm bore provides 3927N. The 500mm stroke demands attention to side-loading; ensure external guide rails support the load to prevent rod binding.
This SKU includes a -S magnet for CMSE/DMSE sensors, PT tapered threads, and a DC24V terminal electrical entry. Note that neither the 5/2 valve nor the adjustable air cushions hold a load without live pressure; for true mechanical locking, consider the SAIL or BSAI series. Replacement requires matching the 80mm bore, 500mm stroke, 1/4 valve port, DC24V terminal coil, and magnet option.
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 SAIF80X500S-08B FAQ
At 0.5 MPa, this 80mm bore cylinder generates 2513N push force and 2268N pull force. The built-in 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) and a maximum frequency of 4 cycles per second.
It uses a DC24V terminal coil (3.0W, IP65, 0.05s response) to drive the 5/2 valve. By factory default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve.
