Airtac SAIF Series Standard Cylinder with Valve SAIF50X700S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X700S-08B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 700mm 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 SAIF50X700S-08B
The AirTAC SAIF50X700S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0 W, it delivers a push force of 982N at 0.5 MPa. The built-in valve offers a 16.0mm2 flow (Cv 0.89) and switches at up to 5 cycles per second. While the bare cylinder rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa.
This unit includes a magnet (-S) for precise position sensing with AirTAC CMSE reed or DMSE electronic switches. The manifold connects to the cylinder via O8xO5 PU tubing, meaning the 1/4" valve port differs from the cylinder's own 1/4" port. Factory-set to retract when energised, the valve can be repositioned to extend on signal, eliminating the need for a separate remote valve and drastically reducing plumbing in decentralized 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 (Ø50mm)

|---|---|---|
| 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 SAIF50X700S-08B Is Used
Decentralized Assembly Stations
Ideal for multi-station machines where running individual valve tubing back to a central manifold is impractical, letting one DC24V signal drive the 982N thrust directly.
Extended Stroke Diverters
The 700mm stroke and integrated 4M210-08 valve provide reliable actuation for diverting products across wider conveyor belts without external plumbing.
Space-Constrained Retrofits
Drop-in solution for older machines needing ISO 15552 interchangeability where adding a separate valve island is physically impossible.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X700S-08B the Right Choice?
Choose this 50mm bore when you need 982N of push force at 0.5 MPa; stepping down to a 40mm bore drops output to 628N, while an 80mm bore yields 2513N if your fixture requires more thrust. The integrated 4M210-08 valve makes this SAIF model superior to a plain SAI cylinder plus remote valve when panel space is tight and running air tubing across a large machine is costly. For position feedback, pair the internal magnet with CMSE or DMSE sensors. To replace this unit, match the 50mm bore, 700mm stroke, 1/4" valve port, DC24V terminal coil, PT thread, and -S magnet.
Because the 700mm stroke exceeds 300mm, ensure adequate side-load guidance to prevent rod binding and premature seal wear. Remember that the 5/2 valve routes air but does not lock the load; if you need true mechanical holding power, consider an AirTAC SAIL lock cylinder instead.
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 SAIF50X700S-08B FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982N of push force and 825N of pull force. The integrated 4M210-08 5/2 valve has an effective area of 16.0mm2 (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
The 5/2 valve is internal piloted and holds its last position via pilot pressure, not a spring. It operates on 0.15-0.8 MPa. Factory-set to retract the rod when the DC24V coil is energised, it can be reconfigured to extend-when-energised simply by repositioning the valve.
