The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X50S-06A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 50mm 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.
The AirTAC SAIF50X50S-06A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-06 5/2 solenoid valve. Featuring an effective orifice of 14.0 mm2 (Cv 0.78), this integrated assembly operates on an AC220V terminal coil drawing 3.5 VA. While the bare cylinder rates to 1.0 MPa, the practical operating range for this valved unit is 0.15-0.8 MPa. It delivers 982 N of push force at 0.5 MPa, making it highly effective for mid-range actuation tasks.
By default, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. The manifold block connects to the cylinder using O8 x O5 PU tubing, meaning the 1/8" valve port differs from the 1/4" cylinder port. Because it switches itself from a single coil signal, this self-valved unit eliminates remote plumbing and is ideal for decentralized installations across large machines. The -S magnet option supports CMSE reed and DMSE electronic sensors for precise position detection.

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.

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).
Eliminates the need for a central valve manifold, allowing independent cylinder control directly at the point of use across large factory layouts.
The built-in valve manifold saves valuable panel and tubing space, fitting neatly into compact assembly cells where external plumbing is impractical.
Ideal for upgrading older machines where routing new pneumatic lines to a remote valve island is costly and complex; only a single electrical signal is needed.
Choose this 50mm bore when you need higher force than a 40mm bore (which provides 628 N push at 0.5 MPa) but do not require the 1559 N push of the 63mm version. The integrated 4M210-06 valve makes the SAIF50X50S-06A superior to a separate cylinder and remote valve setup when panel space is tight and running valve tubing is costly. Select the AC220V terminal connection for standard factory power, and note that the PT thread type is tapered. For replacement, match the 50mm bore, 50mm stroke, 1/4" cylinder port, 1/8" valve port, AC220V voltage, terminal entry, and -S magnet. Remember that the 5/2 valve routes air but does not hold the load without live pressure; for true locking, consider the SAIL series.
Quick checklist
The 50mm bore generates 982 N of push force at 0.5 MPa and 1767 N at 0.9 MPa. The built-in 4M210-06 valve has a 14.0 mm2 orifice, providing a Cv of 0.78 and a maximum operating frequency of 5 cycles per second.
The built-in 5/2 valve allows the cylinder to control itself from a single AC220V coil signal, removing the need for separate remote valves. Factory set to retract when energised, the valve can be repositioned to extend-when-energised if your logic requires it.
