Airtac SAIF Series Standard Cylinder with Valve SAIF40X350S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X350S-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 350mm 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 SAIF40X350S-08A
The AirTAC SAIF40X350S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. Driven by an AC220V terminal coil consuming 3.5 VA, it delivers a 628N push force at 0.5 MPa. The integrated manifold uses an O8xO5 PU tube to bridge the valve and cylinder, eliminating remote plumbing. While the bare cylinder rates to 1.0 MPa, the internal pilot valve operates at 0.15-0.8 MPa, setting the practical working range for the assembly.
Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your cycle logic requires it. This self-switching design requires only one electrical signal to drive the motion, making it highly effective for decentralized stations across large machines. The -S magnet supports CMSE reed and DMSE electronic sensors for precise end-position verification.

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 SAIF40X350S-08A Is Used
Decentralized Assembly Lines
Ideal for large machine layouts where running individual valve tubing back to a central manifold is costly, as this cylinder switches itself via a single AC220V signal.
Compact Clamping Stations
Provides 628N of push force at 0.5 MPa in tight spaces, using the built-in 4M210 valve to minimize panel footprint and external plumbing.
Wire-Optimized Retrofits
Perfect for upgrading existing ISO 15552 fixtures where adding pneumatic lines is difficult, allowing control via a simple 3.5 VA electrical connection.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X350S-08A the Right Choice?
Choose this 40mm bore when you need 628N push force at 0.5 MPa and want to bypass the complexity of a separate cylinder and remote valve. If your application demands higher thrust, stepping up to the 50mm bore yields 982N at the same pressure. Because the stroke is 350mm, ensure adequate guide support to prevent rod side-loading and premature seal wear. The unit includes a carbon steel rod and PT tapered threads.
Remember that the 5/2 valve routes air but does not lock the load mechanically; if unpowered position holding is required, consider the SAIL lock series. For replacements, match the 40mm bore, 350mm stroke, 1/4" valve port, AC220V terminal coil, PT thread, and -S magnet specification exactly.
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 SAIF40X350S-08A 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 and a maximum frequency of 5 cycles per second.
No, the cylinder controls itself from one AC220V coil signal. By default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
