The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X150S-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 150mm 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 SAIF80X150S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and an effective orifice of 25.0 mm2. Driven by a DC24V terminal entry coil consuming 3.0 W, it achieves IP65 protection and a 0.05 s response time. The integrated manifold connects via O10 x O6.5 PU tubing, utilizing a PT1/4 valve port while the cylinder body features a PT3/8 port. A carbon steel rod and included -S magnet enable precise position detection with CMSE reed or DMSE electronic sensors.
While the cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. It delivers 2513 N of push force at 0.5 MPa and reaches a maximum of 513 kgf at 1.0 MPa. Factory set to retract the piston rod when the coil is energised, the valve can be repositioned to extend-when-energised. By switching itself from a single coil signal, it eliminates remote plumbing, saves panel space, and is ideal for decentralized stations across large machines.

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 factory layouts where running separate valve tubing is costly, this self-valved unit operates from a single DC24V signal.
Delivers 2513 N push force at 0.5 MPa for moving heavy workpieces, utilizing the built-in 4M310-08 valve for rapid 4 cycle/sec actuation.
Saves panel space and plumbing on machinery upgrades by integrating the 5/2 valve directly onto the ISO 15552 profile cylinder body.
Select this 80 mm bore when 50 mm (982 N push at 0.5 MPa) is insufficient but 100 mm (3927 N push at 0.5 MPa) is oversized. The self-contained SAIF format outperforms a separate cylinder plus remote valve by cutting tubing runs and wiring, making it optimal for decentralized machine layouts. A 4M310 valve offers a 4 cycle/sec max frequency, suitable for heavy actuation.
For load holding, note that the 5/2 valve routes air but does not lock the cylinder, and the variable air cushions only decelerate near stroke ends. For secure clamping, consider the SAIL or BSAI series. Replacement requires an 80 mm bore, 150 mm stroke, PT1/4 valve port, DC24V voltage, terminal entry, and the -S magnet.
Quick checklist
The 80 mm bore generates 2513 N push and 2268 N pull force at 0.5 MPa. The built-in 4M310-08 5/2 valve provides an effective area of 25.0 mm2 (Cv 1.40).
It uses a DC24V terminal coil (3.0 W, IP65). Factory set to retract the rod when energised, the 5/2 valve can be repositioned to extend-when-energised. It holds position via pilot pressure, eliminating the need for a separate remote valve.
