The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X160S-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm 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.
The AirTAC SAIF50X160S-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-08 5/2 solenoid valve. This integrated assembly delivers a Cv of 0.89 and generates 982N of push force at 0.5MPa. Driven by an AC220V terminal entry coil consuming 3.5VA, it activates in 0.05s. The manifold connects the valve to the cylinder using O8xO5 PU tubing, meaning the 1/4-inch valve port differs from the cylinder's own 1/4-inch port.
Because the cylinder body rates to 1.0MPa but the 4M210 valve operates from 0.15 to 0.8MPa, the practical working range for this self-switching unit is 0.15-0.8MPa. By default, the piston rod retracts when the coil is energised, though you can reconfigure it to extend-when-energised by repositioning the valve. This built-in design eliminates remote plumbing, saving panel space for decentralized machine stations. The -S magnet option supports CMSE reed and DMSE electronic sensors for position tracking.

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).
Ideal for large assembly lines where running individual valve tubing back to a central manifold is costly and complex.
Provides 982N of clamping force at 0.5MPa without requiring external panel space for a separate 5/2 solenoid valve.
Drops directly into existing ISO 15552 footprints, adding self-switching logic via an AC220V terminal signal.
Choose this 50mm bore when you need 982N push force at 0.5MPa; stepping down to a 40mm bore yields 628N, while a 63mm bore provides 1559N. The self-valved SAIF architecture outperforms a separate cylinder and remote valve when floor space is tight and running tubing across a large machine is costly. A single AC220V terminal connection drives the entire actuator.
For replacements, match the 50mm bore, 160mm stroke, 1/4-inch valve port, AC220V voltage, terminal entry, PT thread, and -S magnet. Remember that the 5/2 valve routes air but does not lock the load; for true position holding, consider the SAIL lock variant. The 160mm stroke is under 300mm, so side-load guide considerations are minimal.
Quick checklist
The 50mm bore generates 982N of push force at 0.5MPa. The built-in 4M210-08 valve provides an effective flow area of 16.0mm2 (Cv 0.89).
The integrated 4M210 5/2 valve allows the cylinder to switch itself from a single AC220V signal, eliminating remote plumbing. Factory-set to retract-when-energised, you can reposition the valve to extend-when-energised.
