Airtac SAIF Series Standard Cylinder with Valve SAIF40X160-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X160-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 160mm 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 SAIF40X160-08A
The AirTAC SAIF40X160-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This built-in valve boasts a 16.0 mm2 effective area (Cv 0.89) and operates at a maximum frequency of 5 cycles per second. Configured with an AC220V coil drawing 3.5 VA, it uses a standard terminal electrical entry with PT tapered threads. Because the valve limits the operating pressure, the practical working range for this assembled unit is 0.15-0.8 MPa, despite the cylinder body itself rating to 1.0 MPa. At 0.5 MPa, it generates 628N of push force and 528N of pull force.
By default, the factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. The manifold block connects to the cylinder using O8 x O5 PU tubing, meaning the 1/4-inch valve port differs from the cylinder's own 1/8-inch port. This self-switching design eliminates the need for a separate remote valve, drastically reducing tubing and panel space for decentralized installations across large machines.

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 SAIF40X160-08A Is Used
Decentralized Assembly Stations
Perfect for large automated lines where running individual valve tubing is costly, letting a single AC220V wire drive localized actuation.
Compact Clamping Fixtures
Provides 628N of push force at 0.5 MPa in tight machine envelopes, using the integrated 4M210 valve to minimize external plumbing.
Light Material Diverters
Offers rapid 5 cycle/sec switching to push or retract small packages on conveyors without needing a remote valve bank.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X160-08A the Right Choice?
Choose this 40mm bore when a 32mm bore (providing 402N push at 0.5 MPa) lacks sufficient thrust, but a 50mm bore (982N push) would be physically oversized for your envelope. The SAIF40X160-08A is ideal for space-tight machines where routing wiring to a single AC220V terminal is far more practical than plumbing long pneumatic lines to a centralized valve island. For this 160mm stroke, standard adjustable air cushions at both ends effectively decelerate the load near stroke end. Note that neither the 5/2 valve nor the air cushion acts as a load-holding brake; if you need true position locking during an air loss event, consider the SAIL series instead. When ordering a replacement, confirm the 40mm bore, 160mm stroke, 1/4-inch valve port, AC220V voltage, terminal entry, PT threads, and the absence of a magnet (-S).
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 SAIF40X160-08A FAQ
The cylinder generates 628N of push force and 528N of pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve has a 16.0 mm2 orifice, providing a Cv of 0.89.
No, the integrated 4M210 valve is internally piloted and switches directly from the AC220V terminal signal. By factory default, it retracts the rod when energised, but you can reposition the valve to extend-when-energised.
