The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X300S-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 300mm stroke and a built-in 4M310-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.
The AirTAC SAIF63X300S-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve. This integrated valve delivers a 25.0 mm2 effective area (Cv 1.40) and mounts directly via a manifold block using O10 x O6.5 PU tubing. Driven by an AC220V terminal entry coil consuming 3.5 VA, it activates in 0.05 s with IP65 protection. The assembly operates safely within 0.15-0.8 MPa, delivering 1559 N of push force at 0.5 MPa.
By switching itself from a single coil signal, this unit eliminates remote plumbing and saves panel space for decentralized machine stations. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. The -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors for position feedback.

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 where running individual valve tubing back to a central manifold is costly. The AC220V terminal coil drives the cylinder locally.
Provides 1559 N push force at 0.5 MPa for clamping or pressing mid-weight parts, utilizing the 4M310-08 valve for responsive 4 cycle/sec operation.
Perfect for upgrading existing ISO 15552 interchangeable setups where physical panel space for external valves is unavailable or restricted.
Choose this 63 mm bore when a 50 mm bore (982 N push at 0.5 MPa) lacks thrust, but an 80 mm bore (2513 N) is excessive. The self-valved SAIF63X300S-08A outperforms a separate cylinder and remote valve by cutting tubing runs, wiring complexity, and panel footprint. It features a carbon steel rod, PT tapered threads, a PT3/8 cylinder port, and a 1/4 valve port.
With a 300 mm stroke, use adequate guide rails to manage side loads and prevent rod bending. Remember that the built-in 5/2 valve routes air but does not lock the load; for true position holding under pressure loss, select the SAIL lock series. Replacement requires matching the 63 mm bore, 300 mm stroke, 08 valve port, AC220V terminal coil, PT thread, and -S magnet.
Quick checklist
At 0.5 MPa, the 63 mm bore generates 1559 N of push force and 1402 N of pull force. The built-in 4M310-08 5/2 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a maximum frequency of 4 cycles per second.
The AC220V terminal coil draws 3.5 VA and activates in 0.05 s. By default, the factory setting retracts the rod when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve on the manifold block.
