Airtac SAIF Series Standard Cylinder with Valve SAIF50X200-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X200-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 200mm 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 SAIF50X200-08A
The AirTAC SAIF50X200-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This built-in valve provides an effective flow area of 16.0 mm2 (Cv 0.89) and is mounted directly via a manifold block using O8 x O5 PU tubing. Configured with an AC220V terminal-style coil, it consumes 3.5 VA and achieves an IP65-rated connection with a rapid 0.05 s activation time.
While the bare cylinder body rates to 1.0 MPa, the practical working pressure for this assembled SAIF unit is 0.15-0.8 MPa due to the internal pilot operation of the mounted valve. Delivering a push force of 982 N at 0.5 MPa, it switches itself from a single coil signal to eliminate remote plumbing. The factory default setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised if your sequence requires it.

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 SAIF50X200-08A Is Used
Decentralized Assembly Lines
Eliminates the need for a central valve bank by switching locally at each station, drastically reducing tubing runs and panel space.
Mid-Force Clamping Fixtures
Provides reliable 982 N clamping force at 0.5 MPa directly at the work point without requiring external pilot lines.
Machine Retrofitting
Ideal for upgrading existing pneumatic setups where adding a remote valve manifold would require extensive rewiring.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X200-08A the Right Choice?
Choose this 50mm bore when you need more thrust than the 40mm version (628 N push at 0.5 MPa) but want to avoid the larger envelope of a 63mm cylinder. The self-contained 4M210 valve makes the SAIF50X200-08A ideal for decentralized machine stations where running separate valve tubing is costly or space-prohibitive. With a 200mm stroke, ensure your mechanism provides adequate side-load guidance to prevent rod binding.
Select this exact AC220V terminal configuration when matching existing mains-voltage control panels. To replace this unit, match the 50mm bore, 200mm stroke, 1/4" valve port, AC220V terminal coil, and PT thread. Note that the 5/2 valve routes air but does not lock the load; if you need true mechanical holding force, consider the AirTAC SAIL lock cylinder series 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 SAIF50X200-08A FAQ
At a 0.5 MPa operating pressure, the 50mm bore generates a push force of 982 N and a pull force of 825 N. The integrated 4M210-08 valve provides a Cv of 0.89 to drive these loads at speeds between 30-800 mm/s.
No separate remote valve is needed. The integrated 4M210 5/2 valve operates on AC220V via a terminal connection. By factory default, the piston rod retracts when the coil is energised, but you can reposition the valve on the manifold to extend-when-energised if needed.
