The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X1000S-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 1000mm 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 SAIF50X1000S-08A is a double-acting ISO 15552 profile cylinder featuring a factory-mounted 4M210-08 5/2 solenoid valve. This integrated assembly delivers a Cv of 0.89 and operates on an AC220V terminal coil drawing 3.5 VA. Because the cylinder body rates to 1.0 MPa but the internal pilot valve limits pressure to 0.15-0.8 MPa, the practical working range for the assembled unit is 0.15-0.8 MPa. At 0.5 MPa it generates 982N of push force and 825N of pull force.
By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This self-contained design switches directly from one coil signal, eliminating remote valves and extra tubing for decentralized stations. The manifold connects to the cylinder via an O8xO5 PU tube, and the unit includes an -S magnet for CMSE reed or DMSE solid-state sensors.

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 machines with distributed stations, eliminating long air lines from a central panel by switching locally via the AC220V coil.
Suitable for 1000mm stroke applications like material push-off or long-indexing tasks where integrated valve control simplifies plumbing.
Fits upgrades where adding external valve islands is impossible, providing a complete 5/2 pneumatic control directly on the cylinder body.
Choose this 50mm bore when 40mm (628N push at 0.5 MPa) is too weak or 63mm (1559N) is oversized. The 4M210-08 valve provides 16.0mm2 effective area, offering a balance of flow and speed within the 30-800 mm/s range. A self-valved SAIF excels over a separate cylinder and remote valve when panel space is tight and wiring multiple decentralized stations is costly. The AC220V terminal connection offers straightforward wiring, and the PT thread ports match standard tapered fittings.
Since the stroke is 1000mm, adding an external guide rail is recommended to manage side loads and prevent rod binding over extended travel. Remember that the 5/2 valve routes air but does not lock the load; for position holding under pressure loss, select an AirTAC SAIL lock cylinder instead. To replace this unit, match the 50mm bore, 1000mm stroke, 1/4" valve port, AC220V voltage, terminal entry, PT threads, and -S magnet.
Quick checklist
The 50mm bore generates 982N push and 825N pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve has a 16.0mm2 orifice with a Cv of 0.89.
No, the 4M210-08 valve is mounted directly on the cylinder. Driven by an AC220V terminal coil, it switches the cylinder from one signal. Factory-set to retract when energised, it can be repositioned to extend when energised.
