Airtac SAIF Series Standard Cylinder with Valve SAIF50X100S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X100S-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 100mm stroke and a built-in 4M210-08 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 SAIF50X100S-08A
The AirTAC SAIF50X100S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. Delivering a Cv of 0.89, this integrated assembly operates on an AC220V terminal connection. The cylinder body rates to 1.0 MPa, but because the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for the assembled unit is 0.15-0.8 MPa. It delivers 982 N of push force at 0.5 MPa, making it suited for medium-duty handling.
By integrating the valve directly on a manifold block, this unit switches itself from one coil signal, eliminating remote plumbing and saving panel space for decentralized machine stations. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The manifold connects to the cylinder via PU tubing (O8 x O5), and the -S magnet works with AirTAC CMSE reed and DMSE electronic sensors.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAIF50X100S-08A Is Used
Decentralized Assembly Lines
Eliminates the need for a central valve manifold, allowing independent 220V control of multiple clamping stations across a large machine layout.
Space-Constrained Machinery
The built-in 4M210 valve saves valuable panel and floor space by mounting the flow control directly to the ISO 15552 profile cylinder.
Retrofit and Upgrade Projects
Ideal for upgrading older machines where running new pneumatic tubing from a remote valve bank to each actuator is costly and complex.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X100S-08A the Right Choice?
Choose this 50mm bore when 32mm (402 N push at 0.5 MPa) is too weak or 63mm (1559 N push at 0.5 MPa) is oversized. The self-valved SAIF design beats a separate cylinder plus remote valve when you need decentralized stations, less tubing, and simpler wiring. The 4M210-08 valve has a 1/4" port, while the cylinder port is also 1/4". The coil uses AC220V with a terminal entry, drawing 3.5 VA with IP65 protection and a 0.05 s response time. Thread type is PT.
For replacements, match the 50mm bore, 100mm stroke, 1/4" valve port, AC220V voltage, terminal entry, PT thread, and the -S magnet. Note that the 5/2 valve routes air but does not hold the load without live pressure; it is not a lock. For load-holding applications, consider the SAIL series.
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 SAIF50X100S-08A FAQ
The 50mm bore provides 982 N of push force and 825 N of pull force at 0.5 MPa. The built-in 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89) and a maximum frequency of 5 cycles per second.
The built-in 5/2 valve allows the cylinder to switch itself from a single coil signal, reducing tubing and panel space for decentralized installations. By factory default, the rod retracts when the coil is energised, but you can reposition the valve to make it extend-when-energised.
