Airtac SAIF Series Standard Cylinder with Valve SAIF50X125S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X125S-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 125mm stroke and a built-in 4M210-06 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 SAIF50X125S-06B
The AirTAC SAIF50X125S-06B is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring a built-in 4M210-06 5/2 solenoid valve. This integrated valve provides a 14.0 mm2 effective area (Cv 0.78) and connects to the manifold via PU tubing (O8 x O5). Driven by a DC24V terminal entry coil drawing 3.0 W with IP65 protection, it responds in 0.05 s. The cylinder bore accepts a PT 1/4 port, while the valve utilizes a PT 1/8 port.
Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. It delivers 982 N of push force at 0.5 MPa. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. Equipped with a magnet, it supports CMSE reed and DMSE electronic sensors for position feedback.

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 SAIF50X125S-06B Is Used
Decentralized Automation Stations
Eliminates the need for a remote valve bank, allowing independent cylinder control directly at the machine station to reduce plumbing complexity.
Space-Constrained Machinery
The built-in 5/2 valve manifold saves valuable panel and footprint space in tight equipment layouts where external tubing is impractical.
Retrofit & Upgrade Projects
Ideal for upgrading existing lines where running new pneumatic tubing back to a central control panel is cost-prohibitive or physically difficult.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X125S-06B the Right Choice?
Choose this 50 mm bore when you need roughly 982 N push force at 0.5 MPa; step down to a 40 mm bore for 628 N, or up to a 63 mm bore for 1559 N. A self-valved SAIF beats a separate cylinder and remote valve when you want to save panel space and eliminate long tubing runs across decentralized machine stations. This configuration uses a DC24V terminal coil, PT thread, and a 4M210-06 valve with a 1/8 port. For load-holding applications, note that the 5/2 valve routes air but does not lock the piston; consider the SAIL series for mechanical locking needs. Replacement requires matching the 50 mm bore, 125 mm stroke, 06 valve port, DC24V voltage, terminal entry, and -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 SAIF50X125S-06B FAQ
The 50 mm bore provides 982 N push and 825 N pull force at 0.5 MPa. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
No, the SAIF50X125S-06B switches itself from one DC24V coil signal using the built-in 5/2 valve. By default, the piston rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
