Airtac SAIF Series Standard Cylinder with Valve SAIF63X80S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X80S-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 80mm 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 SAIF63X80S-08A
The AirTAC SAIF63X80S-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve. Driven by an AC220V terminal coil drawing 3.5 VA, it delivers a 1559N push force at 0.5 MPa. The integrated valve features a 25.0 mm2 orifice (Cv 1.40) and switches at up to 4 cycles per second. Because the valve manifold mounts directly using O10 x O6.5 PU tubing, you save panel space and eliminate remote plumbing.
While the bare cylinder body rates to 1.0 MPa, the integrated 5/2 valve limits the practical SAIF operating range to 0.15-0.8 MPa. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend on signal instead. This -S variant includes a magnet for position sensing and works with AirTAC CMSE reed or DMSE electronic solid-state 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 (Ø63mm)

| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 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 SAIF63X80S-08A Is Used
Decentralized Automation Cells
Distribute actuation across large machines without running long valve tubing back to a central manifold, saving wiring and plumbing time.
Mid-Force Positioning
Provides 1559N of push force at 0.5 MPa for clamping or lifting workpieces, switching reliably at up to 4 cycles per second.
Space-Constrained Retrofits
Drop-in ISO 15552 dimensions with a built-in valve manifold minimize envelope size where external valve banks will not fit.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X80S-08A the Right Choice?
Choose this self-valved unit when decentralized machine stations require robust actuation without the wiring and tubing overhead of a separate remote valve. If your application needs less force, stepping down to a 50mm bore yields 982N push at 0.5 MPa; if you need more, an 80mm bore provides 2513N. For this AC220V terminal configuration, ensure your control system matches the coil voltage and provides IP65-rated connections. The cylinder port is 1/4, while the valve port is also 1/4. If your machine requires true load holding without live air pressure, note that the 5/2 valve routes air but does not lock the piston; consider an AirTAC SAIL lock cylinder instead.
When ordering a replacement, verify the 63mm bore, 80mm stroke, PT tapered port threads, carbon steel rod, and the -S magnet option. The exact valve assembly is a 4M310-08 with an AC220V terminal entry coil.
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 SAIF63X80S-08A FAQ
At 0.5 MPa, the 63mm bore generates 1559N of push force and 1402N of pull force. The integrated 4M310-08 valve provides an effective flow area of 25.0 mm2 (Cv 1.40).
The factory default setting retracts the rod when the AC220V coil is energised. By repositioning the built-in 5/2 valve, you can reconfigure it to extend when energised instead.
