Airtac SAIF Series Standard Cylinder with Valve SAIF80X1000S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X1000S-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 1000mm 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.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF80X1000S-08B
The AirTAC SAIF80X1000S-08B is a double-acting ISO 15552 profile cylinder engineered with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 orifice. Driven by a DC24V terminal coil consuming 3.0 W, it integrates switching directly on the actuator. While the cylinder body rates to 1.0 MPa, the integrated valve limits the practical operating pressure to 0.15-0.8 MPa. It delivers 2513 N of push force at 0.5 MPa and operates at speeds of 30-800 mm/s.
By integrating the valve and manifold, this unit eliminates remote plumbing and saves panel space, making it ideal for decentralized stations across large machines. The manifold connects to the cylinder using PU tube (O10 x O6.5). Factory-set to retract the piston rod when the coil is energised, the valve can be repositioned to extend-when-energised. This -S variant includes a magnet for position sensing with CMSE reed or DMSE electronic switches.

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.
Theoretical Output Force (Ø80mm)

| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
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).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF80X1000S-08B Is Used
Decentralized Automation Stations
Eliminates the need for long air lines back to a central valve manifold on large factory floors, driving heavy 80mm actuators directly from a local DC24V signal.
Long-Stroke Material Handling
Provides the 2513 N push force needed for diverting or lifting heavy pallets over a 1000mm travel, while keeping the valve footprint minimal along the conveyor line.
Space-Constrained Machinery
Fits into tight machine envelopes where running separate valve tubing is costly, using the integrated 4M310 valve and DMSE sensors for precise end-of-stroke confirmation.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X1000S-08B the Right Choice?
Choose this 80mm bore when you need substantial thrust, such as the 2513 N push force at 0.5 MPa, stepping up from a 63mm bore that offers 1559 N. The 1000mm stroke on this profile cylinder requires careful guidance to manage side loads and prevent rod deflection over the extended travel. The self-valved SAIF design beats a separate cylinder plus remote valve in space-tight machines by cutting tubing runs and wiring to a single coil signal. Remember that the 5/2 valve routes air but does not lock the load; for true position holding under pressure loss, select a SAIL lock cylinder instead. To replace this exact unit, match the 80mm bore, 1000mm stroke, 4M310-08 valve (1/4" valve port), 3/8" cylinder port, DC24V terminal coil, PT threads, and the -S magnet.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF80X1000S-08B FAQ
The 80mm bore generates 2513 N push force and 2268 N pull force at 0.5 MPa. The built-in 4M310-08 5/2 valve provides an effective flow area of 25.0 mm2 (Cv 1.40) and can cycle up to 4 times per second.
The DC24V terminal coil drives the 5/2 valve, which is factory-set to retract the rod when energised but can be reconfigured to extend-when-energised by repositioning the valve. The valve routes air but does not lock the load; it requires live pressure to hold position, so use a SAIL cylinder if true mechanical locking is needed.
