The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X700-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 700mm 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 SAIF50X700-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific configuration uses an AC220V coil with a terminal electrical entry, consuming 3.5 VA and responding in 0.05 s. The built-in valve has an effective area of 16.0 mm2 (Cv 0.89) and connects to the cylinder bore via O8 x O5 PU tubing, eliminating the need for separate remote pneumatic plumbing. While the bare cylinder rates to 1.0 MPa, the practical working pressure for this valved assembly is 0.15-0.8 MPa, delivering 982 N of push force at 0.5 MPa.
By default, the factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design is highly advantageous for decentralized installations across large machines, as one electrical signal drives the actuator without extensive air tubing runs. The assembly operates at speeds of 30-800 mm/s and includes adjustable air cushions at both ends to decelerate the rod near stroke completion.

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.

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 by driving the actuator directly from a single AC220V signal, drastically reducing tubing runs across large factory layouts.
Provides 982 N of push force at 0.5 MPa over a 700mm travel distance, utilizing adjustable air cushions to safely decelerate the rod at stroke end.
Ideal for upgrading existing machinery where adding external pneumatic plumbing is difficult, as the built-in 4M210 valve handles switching internally.
Choose this 50mm bore if your application requires around 982 N of push force at 0.5 MPa; stepping down to a 40mm bore drops the push force to 628 N, while upgrading to a 63mm bore increases it to 1559 N. The integrated 4M210-08 valve makes this SAIF unit superior to a standard SAI cylinder with a remote valve bank when panel space is tight and running dedicated air lines is costly. Because this 700mm stroke exceeds 300mm, you must account for potential rod side-loading and utilize appropriate guide rails to prevent premature seal wear. Remember that the 5/2 valve routes air but does not lock the load mechanically; for position holding without live pressure, consider the SAIL lock cylinder instead. When ordering a replacement, verify the 50mm bore, 700mm stroke, 1/4" valve port, AC220V voltage, terminal entry, PT thread, and the absence of a magnet (-S).
Quick checklist
At 0.5 MPa, this 50mm bore cylinder provides 982 N of push force and 825 N of pull force. The maximum push force reaches 1767 N at 0.7 MPa.
Yes. The factory setting retracts the rod upon energising the AC220V coil, but you can reposition the built-in 4M210-08 5/2 valve to make it extend-when-energised.
