Airtac SAIF Series Standard Cylinder with Valve SAIF40X700S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X700S-08B is a genuine double-acting ISO 15552 cylinder with a Ø40mm 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 SAIF40X700S-08B
The AirTAC SAIF40X700S-08B is a double-acting ISO 15552 profile cylinder engineered with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89. Driven by a DC24V terminal coil drawing 3.0 W, it eliminates the need for remote plumbing. The integrated manifold uses O8xO5 PU tubing to bridge the valve and cylinder. While the bare cylinder rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa, yielding 628N of push force at 0.5 MPa.
From the factory, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This 700mm stroke unit includes a magnet for position sensing with CMSE reed or DMSE electronic switches. Because the 5/2 valve routes air rather than locking it, use a SAIL lock cylinder if you need true load holding.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAIF40X700S-08B Is Used
Decentralized Assembly Lines
Ideal for large machines where each station controls itself from one DC24V signal, cutting panel space and tubing runs.
Material Handling Gates
Provides 628N push force at 0.5 MPa to actuate routing gates directly on the conveyor frame without external valves.
Space-Tight Retrofits
Drops into older machines where adding a remote valve island is impossible, using the built-in 4M210 manifold.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X700S-08B the Right Choice?
Choose this 40mm bore when a 32mm bore (402N push at 0.5 MPa) lacks the force for your actuation, but a 50mm bore (982N at 0.5 MPa) is physically too large. The SAIF40X700S-08B is ideal for decentralized stations where running separate valve tubing is costly. The built-in 4M210 valve with a 1/4" valve port and PT1/4" cylinder port simplifies installation. At 700mm stroke, prevent rod sag and side-load damage by using a guide bearing. To replace this unit, match the 40mm bore, 700mm stroke, 1/4" valve port, DC24V terminal coil, PT thread, and -S 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 SAIF40X700S-08B FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5 MPa. The integrated 4M210-08 5/2 valve has a 16.0 mm2 orifice with a Cv of 0.89.
Yes, the factory setting retracts the rod when the DC24V coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 valve routes air and does not hold the load without live pressure; for load holding, consider a SAIL lock cylinder.
