Airtac SAIF Series Standard Cylinder with Valve SAIF40X150-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X150-08A is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 150mm 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 SAIF40X150-08A
The AirTAC SAIF40X150-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. With a 16.0 mm2 orifice (Cv 0.89) and a 5 cycle/sec max frequency, this integrated assembly switches itself from a single AC220V terminal coil signal, eliminating remote plumbing. The cylinder port is PT1/4, while the valve uses a 1/4 inch port connected via an O8xO5 PU tube manifold block.
While the bare cylinder rates to 1.0 MPa, the practical SAIF operating range is 0.15-0.8 MPa due to the internal pilot valve limits. Delivering 628N push and 528N pull at 0.5 MPa, it suits decentralized stations across large machines. Factory set to retract when energised, the valve can be repositioned to extend on signal. The assembly holds no load without live pressure; point to SAIL for mechanical locking.

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 SAIF40X150-08A Is Used
Decentralized Assembly Lines
Mounts directly at station points to actuate clamps without routing air lines back to a central manifold.
Compact Machine Routing
Fits space-tight machinery by combining the actuator and switching valve into one envelope.
Retrofit Automation
Upgrades existing ISO 15552 mounts where adding separate valve plumbing is costly or impractical.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X150-08A the Right Choice?
Select this 40mm bore when a 32mm bore (402N push at 0.5 MPa) is insufficient, but a 50mm bore (982N push) is oversized. The self-valved SAIF40X150-08A excels over a separate cylinder and remote valve by saving panel space, reducing wiring, and cutting tubing runs in decentralized machine layouts. It operates at 30-800 mm/s.
Choose this AC220V terminal entry coil for standard mains voltage control, drawing 3.5 VA with IP65 protection and a 0.05s response. For stroke lengths of 150mm or more, verify guide tolerances to prevent excessive side-load on the rod. Replacement requires matching the 40mm bore, 150mm stroke, 1/4 inch valve port, AC220V terminal coil, PT thread, and no magnet (-S). Add an -S magnet for CMSE reed or DMSE electronic sensors.
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 SAIF40X150-08A FAQ
The 40mm bore generates 628N push and 528N pull at 0.5 MPa. The integrated 4M210-08 valve provides a 16.0 mm2 effective area (Cv 0.89).
No, it features a built-in 4M210 5/2 valve driven by an AC220V terminal coil. Factory set to retract when energised, it can be repositioned to extend on signal, enabling decentralized control.
