Airtac SAIF Series Standard Cylinder with Valve SAIF100X500S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X500S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm 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 SAIF100X500S-08B
The AirTAC SAIF100X500S-08B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. It delivers 3927N of push force at 0.5MPa and utilizes a carbon steel piston rod. Equipped with a magnet (-S), it supports CMSE reed and DMSE electronic sensors for precise position detection. The integrated valve provides a Cv of 1.40 and a maximum frequency of 4 cycles per second. Because the valve operates at 0.15-0.8MPa, this defines the practical working pressure range for the assembled unit, even though the bare cylinder rates to 1.0MPa.
This specific SKU specifies a DC24V terminal entry coil consuming 3.0W with an IP65 rating and a 0.05s response time. The manifold connects to the cylinder using PU tubing (O10xO6.5), and the valve's 1/4" PT port is distinct from the cylinder's 1/2" PT port. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This self-switching design eliminates remote plumbing, saving panel space for decentralized machine stations.

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 (Ø100mm)

| 0.7 MPa | 5498 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 SAIF100X500S-08B Is Used
Decentralized Automation
Ideal for large factory systems where running individual valve tubing is costly, letting each station control itself via a single DC24V signal.
Heavy Material Handling
Provides the high push force needed to move heavy pallets or components directly at the work point without external valve banks.
Retrofits & Upgrades
Perfect for machinery upgrades where panel space is tight, integrating the 5/2 valve directly onto the cylinder manifold.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X500S-08B the Right Choice?
Choose this 100mm bore SAIF when your application requires substantial thrust, such as the 3927N push force at 0.5MPa, and you want to avoid the tubing runs of a separate cylinder plus remote valve. If you need less force, stepping down to a 63mm bore yields 1559N at 0.5MPa. The integrated 4M310-08 valve handles its own air routing via internal pilot pressure, meaning the 5/2 valve holds its last position dynamically but does not mechanically lock the load; for true load-holding, consider the SAIL series instead. With a 500mm stroke, ensure adequate guiding to prevent excessive side-loading on the rod. To replace this unit, match the 100mm bore, 500mm stroke, 1/4" valve port, DC24V voltage, terminal entry, PT threads, and the -S magnet.
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 SAIF100X500S-08B FAQ
At 0.5MPa, it provides 3927N of push force and 3681N of pull force. The integrated 4M310-08 valve has an effective area of 25.0mm2 (Cv 1.40).
You do not need a remote valve. The built-in 5/2 valve operates on a DC24V terminal signal, and by default retracts the rod when energised, though it can be repositioned to extend-when-energised.
