Airtac SAIF Series Standard Cylinder with Valve SAIF50X1000-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X1000-08B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 1000mm 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 SAIF50X1000-08B
The AirTAC SAIF50X1000-08B is a double-acting ISO 15552 profile cylinder paired with a built-in 4M210-08 5/2 solenoid valve, offering a Cv of 0.89. Driven by a DC24V terminal coil consuming 3.0W with IP65 protection, it switches itself from one electrical signal. The integrated manifold connects via O8xO5 PU tubing, meaning the valve port differs from the cylinder port. Although the cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa.
Providing 982N of push force at 0.5 MPa, this 50mm bore unit eliminates the need for a separate remote valve, saving panel space and plumbing. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. Please note the 1000mm stroke is a non-standard length for this bore.

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 SAIF50X1000-08B Is Used
Decentralized Automation
Eliminates remote valve plumbing on large machines by driving the 1000mm stroke directly from a local DC24V signal.
Space-Constrained Machinery
Saves valuable panel space by integrating the 4M210-08 valve directly onto the cylinder manifold block.
Long-Stroke Assembly
Handles extended 1000mm actuation tasks with 982N push force, guided externally to prevent rod side-loading.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X1000-08B the Right Choice?
Choose this 50mm bore if you need 982N push force at 0.5 MPa; stepping down to a 40mm bore yields 628N, while a 63mm bore provides 1559N. The self-valved SAIF design beats a separate cylinder and remote valve for decentralized stations by cutting tubing runs and wiring. For load-holding, note the 5/2 valve routes air but does not lock; use SAIL for pneumatic locking. Because this unit features a 1000mm stroke, mounting guides is critical to prevent rod side-loading and premature wear. Replacement requires matching the 50mm bore, 1000mm stroke, 1/4" valve port, DC24V terminal coil, PT thread, and no magnet.
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 SAIF50X1000-08B FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982N of push force and 825N of pull force. The maximum push force is 1767N at 0.7 MPa.
It uses a 4M210-08 5/2 solenoid valve. The factory setting retracts the rod when the DC24V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
