Airtac SAIF Series Standard Cylinder with Valve SAIF40X600S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X600S-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 600mm 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 SAIF40X600S-08A
The AirTAC SAIF40X600S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. Equipped with a magnetic piston (-S) for CMSE reed and DMSE electronic sensors, it delivers 628N of push force at 0.5 MPa. The integrated valve offers a 16.0mm2 orifice (Cv 0.89) and operates at 30-800mm/s. Because the manifold uses an O8xO5 PU tube to bridge the valve and cylinder, the valve port (1/4) is intentionally distinct from the cylinder port (1/4).
This assembly is driven by an AC220V terminal coil consuming 3.5 VA, featuring IP65 protection and a 0.05s activation time. While the cylinder body rates to 1.0 MPa, the internal pilot valve limits the practical working range to 0.15-0.8 MPa. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design eliminates remote valves, saving panel space and tubing across 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 (Ø40mm)

| 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 SAIF40X600S-08A Is Used
Decentralized Assembly Stations
Eliminates the need for a central valve bank by driving the 600mm stroke directly from a local AC220V signal, reducing machine tubing complexity.
Inline Product Sorting
Provides 628N of push force at 0.5MPa to deflect packages, utilizing the built-in 4M210 valve for rapid 5 cycle/sec operation.
Space-Constrained Automation
Integrates the valve and cylinder into one envelope, fitting easily into tight retrofit spaces where running separate valve tubing is costly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X600S-08A the Right Choice?
Choose this 40mm bore when a 32mm cylinder (402N push at 0.5MPa) lacks thrust, but a 50mm bore (982N push) is oversized. The 600mm stroke requires external guide support to prevent rod side-loading and premature seal wear. Since the stroke is under the 1200mm standard maximum, it ships as a standard configuration.
A self-valved SAIF unit excels over a separate cylinder and remote valve by cutting wiring and plumbing complexity. To replace this assembly, match the 40mm bore, 600mm stroke, 1/4 valve port, AC220V terminal coil, PT thread, and -S magnet. Remember that the 5/2 valve routes air but does not lock the load; for position holding, consider an AirTAC SAIL pneumatic lock cylinder.
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 SAIF40X600S-08A FAQ
The 40mm bore generates 628N push and 528N pull force at 0.5MPa. The built-in 4M210-08 5/2 valve has a 16.0mm2 effective area (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
No, the 5/2 valve routes air but does not lock the load pneumatically. By factory default, the rod retracts when the AC220V coil is energised, but you can reposition the valve to extend-when-energised. For true load holding, use an AirTAC SAIL cylinder.
