Airtac SAIF Series Standard Cylinder with Valve SAIF50X75-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X75-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 75mm 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 SAIF50X75-08A
The AirTAC SAIF50X75-08A is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89 and 982N of push force at 0.5 MPa. It features an AC220V coil with a terminal electrical entry consuming 3.5 VA. Because the integrated valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembled unit, even though the bare cylinder rates to 1.0 MPa. The manifold connects to the cylinder via O8 x O5 PU tubing.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This self-contained design eliminates the need for a remote valve bank, reducing tubing and panel space for decentralized machine stations. The unit uses a carbon steel rod and PT tapered threads.

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 SAIF50X75-08A Is Used
Decentralized Stations
Perfect for large machines with decentralized stations, driving the 982N push force directly from a single AC220V signal without a remote valve bank.
Space-Tight Handling
Ideal for compact assembly lines where panel space is limited, using the built-in 4M210-08 valve and short PU tubing to minimize plumbing.
Retrofit Automation
Suits retrofits where adding new valve tubing is costly, relying on the terminal entry coil and self-switching 5/2 valve to control the 75mm stroke.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X75-08A the Right Choice?
Choose this 50mm bore when 40mm falls short on thrust (628N push at 0.5 MPa) or 63mm is excessive (1559N push). The integrated 4M210 valve makes the SAIF50X75-08A ideal for space-constrained machines where running separate valve tubing is costly. It operates at 30-800 mm/s. Remember that the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL lock series. Replacement requires matching the 50mm bore, 75mm stroke, 1/4" valve port, AC220V terminal coil, and PT threads.
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 SAIF50X75-08A FAQ
The 50mm bore cylinder provides 982N push and 825N pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve has an effective area of 16.0 mm2 (Cv 0.89) and a max frequency of 5 cycles/sec.
No, the 5/2 valve routes air and does not lock the load. The unit uses an AC220V terminal entry coil (3.5 VA, IP65). By factory default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
