Airtac SAIF Series Standard Cylinder with Valve SAIF50X100-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X100-08A 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 SAIF50X100-08A
The AirTAC SAIF50X100-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific configuration pairs a 50mm bore delivering 982N push force at 0.5MPa with an AC220V terminal coil. Because the manifold block routes air directly via O8xO5 PU tubing, you eliminate remote plumbing. The assembly operates within a 0.15-0.8MPa range, as the built-in valve limits the 1.0MPa cylinder capacity, ensuring reliable 30-800mm/s speeds.
By default, the piston rod retracts when the coil is energised, but you can reconfigure the valve to extend-when-energised by simply repositioning it. The 4M210-08 valve provides a 16.0mm2 effective area (Cv 0.89) and switches at up to 5 cycles per second. Driven by a single AC220V signal drawing 3.5 VA, it offers IP65 protection and a 0.05s response time for decentralized machine 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 SAIF50X100-08A Is Used
Decentralized Assembly Stations
Ideal for large machines where running valve tubing is costly, this self-valved cylinder drives clamping actions directly from a single AC220V signal.
Compact Packaging Equipment
The integrated 4M210-08 valve saves panel space while delivering 982N push force at 0.5MPa for product sorting and positioning tasks.
Material Handling Diverters
Provides rapid 30-800mm/s actuation with a 0.05s coil response, perfect for diverting packages on tight conveyors where external valves are impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X100-08A the Right Choice?
Choose this 50mm bore when your application requires around 982N of push force at 0.5MPa; step down to a 40mm bore if you only need 628N, or up to a 63mm bore for 1559N. A self-valved SAIF50X100-08A excels over a separate cylinder and remote valve in space-tight machines, cutting panel space and wiring complexity. The 1/4" valve port and PT1/4" cylinder port provide balanced flow for this bore size.
When ordering a replacement, verify the 50mm bore, 100mm stroke, 1/4" valve port, AC220V voltage, terminal entry, PT thread, and absence of a magnet (-S). Note that the 5/2 valve routes air but does not lock the load; for position holding without live pressure, consider the SAIL lock series. For this 100mm stroke, side-load guides are not strictly required, but always ensure adequate mounting support.
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 SAIF50X100-08A FAQ
The 50mm bore cylinder provides 982N push force and 825N pull force at 0.5MPa. The integrated 4M210-08 valve has a 16.0mm2 effective orifice area with a Cv of 0.89.
No, the integrated 5/2 valve controls the cylinder directly from one AC220V coil signal. By factory default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
