Airtac SAIF Series Standard Cylinder with Valve SAIF63X150-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X150-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm 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.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF63X150-08A
The AirTAC SAIF63X150-08A is a double-acting profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a push force of 1559 N at 0.5 MPa. The integrated valve offers an effective area of 25.0 mm2 (Cv 1.40) and mounts directly via a manifold block using PU tubing (O10 x O6.5). Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembled unit, even though the cylinder body rates to 1.0 MPa. This configuration features an AC220V terminal coil drawing 3.5 VA, IP65 protection, and a 0.05 s activation time.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This self-switching design eliminates remote plumbing and panel space, making it ideal for decentralized stations across large machines. The base cylinder is dimensionally interchangeable per ISO 15552, utilizing a carbon steel rod and PT tapered ports.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF63X150-08A Is Used
Decentralized Automation
Eliminates the need for a remote valve bank, allowing independent cylinder control directly at the machine station.
Mid-Force Assembly
Provides 1559 N of push force at 0.5 MPa for driving mid-sized clamps and actuators in tight machinery envelopes.
Retrofit Upgrades
Ideal for upgrading existing lines where routing new air lines to a central manifold is impractical or expensive.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X150-08A the Right Choice?
Choose this 63mm bore when 50mm lacks thrust; stepping up to 80mm yields 2513 N push at 0.5 MPa if your application demands higher load. The SAIF63X150-08A with its 4M310-08 valve and AC220V terminal coil suits machines where running separate valve tubing is costly. Remember the 5/2 valve routes air and does not lock the load; for position holding under pressure loss, consider the SAIL lock series. For replacement, verify the 63mm bore, 150mm stroke, 1/4" valve port, PT cylinder port, AC220V voltage, terminal entry, and no magnet (-S).
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 SAIF63X150-08A FAQ
The built-in 4M310-08 valve has a 25.0 mm2 orifice (Cv 1.40). The 63mm bore cylinder generates 1559 N push and 1402 N pull force at 0.5 MPa.
It uses a 5/2 solenoid valve driven by an AC220V terminal coil. The factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised. No separate remote valve is needed.
