Airtac SAIF Series Standard Cylinder with Valve SAIF40X350S-06A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X350S-06A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 350mm stroke and a built-in 4M210-06 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-06A
The AirTAC SAIF40X350S-06A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-06 5/2 solenoid valve. Delivering a Cv of 0.78 and a 14.0 mm2 effective area, this decentralized unit switches itself from one AC220V terminal coil signal, eliminating the need for remote plumbing. The cylinder pushes with 628 N at 0.5 MPa, while the integrated valve manifold uses an O8 x O5 PU tube to bridge the valve and cylinder. Because the valve limits the assembly, the practical operating pressure is 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 specific SKU includes a magnet for position sensing with AirTAC CMSE reed or DMSE electronic sensors. The carbon steel rod and extruded aluminum barrel provide durable service, and the assembly runs at speeds of 30-800 mm/s without requiring lubrication.

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-06A Is Used
Decentralized Automation
Perfect for large factory layouts where running individual valve tubing back to a central panel is costly and complex.
Space-Constrained Machinery
The built-in valve manifold minimizes the pneumatic footprint, fitting easily into tight machine cells.
Material Handling
Provides reliable 628N push force for diverting or gating packages on a conveyor line at up to 5 cycles per second.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X350S-06A the Right Choice?
Choose this 40mm bore when you need 628 N of push force at 0.5 MPa, stepping up from the 32mm bore which offers 402 N. The integrated 4M210-06 valve features a PT1/8 port and operates at a maximum frequency of 5 cycles per second. This self-valved design is ideal for decentralized stations across large machines, drastically reducing tubing and wiring compared to a separate cylinder and remote valve setup. Remember that the 5/2 valve routes air and is not a lock; if your application requires load-holding, consider the SAIL series instead.
With a stroke of 350mm, this cylinder requires adequate side-load support; use a guide rail to prevent rod binding. To replace this unit, match the 40mm bore, 350mm stroke, 4M210-06 valve with PT1/8 ports, AC220V terminal coil, and the -S magnet option.
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-06A FAQ
The 40mm bore cylinder provides 628 N push force and 528 N pull force at 0.5 MPa. The built-in 4M210-06 valve has an effective area of 14.0 mm2 (Cv 0.78) and a maximum frequency of 5 cycles per second.
The factory setting retracts the rod when the AC220V coil is energised. By repositioning the valve on the manifold, you can reconfigure it to extend-when-energised. The 5/2 valve holds its position pneumatically, so no separate remote valve is needed.
