Airtac SAIF Series Standard Cylinder with Valve SAIF50X100S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X100S-08B 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-08B
The AirTAC SAIF50X100S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve (Cv 0.89). Driven by a DC24V terminal entry coil consuming 3.0 W, it switches itself from one signal, eliminating remote plumbing. The cylinder body rates to 1.0 MPa, but the practical operating range is 0.15-0.8 MPa due to the valve's pilot pressure limits. At 0.5 MPa it delivers 982N push and 825N pull force.
This assembly includes a magnet for position sensing with CMSE reed and DMSE electronic switches. The manifold connects via O8xO5 PU tubing, and the valve port (1/4) differs from the standard cylinder port (1/4). Factory-set to retract when energised, the valve can be repositioned to extend on signal, offering decentralized machine control without a separate valve island.

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-08B Is Used
Decentralized Machine Stations
Eliminates the need for a central valve bank, driving individual stations directly via the DC24V signal.
Compact Assembly Automation
Saves panel space and reduces tubing runs in tight machinery where 982N of push force is sufficient.
Retrofit & Upgrade Projects
Ideal for upgrading existing ISO 15552 lines without routing new pneumatic lines back to a main manifold.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X100S-08B the Right Choice?
Choose this 50mm bore when you need around 982N of push force at 0.5 MPa; stepping down to a 40mm bore drops output to 628N, while an 80mm bore offers 2513N for heavier loads. A self-valved SAIF excels over a standard cylinder plus remote valve in space-constrained machines, cutting tubing and panel space. Ensure your control system matches the DC24V terminal coil, and specify the -S magnet for CMSE/DMSE sensors. The 5/2 valve routes air but does not lock the load; for true position holding, specify an AirTAC SAIL lock cylinder.
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-08B FAQ
The 50mm bore generates 982N push and 825N pull force at 0.5 MPa. The built-in 4M210-08 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a max frequency of 5 cycles/sec.
No, the 5/2 solenoid valve routes air but does not lock the piston. By default, the cylinder retracts when the DC24V coil is energised, but it can be repositioned to extend on signal. For true load holding, consider the AirTAC SAIL series.
